| As a kind of high performance polymer, poly(aryl ketone) has been developed for several decades. Therefore the synthetic method, structure variety and capability of polyarylketone have been promoted greatly. However, the wide application of the polyarylketone have been restricted by its quality of high preparative cost, insoluble and refractory. Accordingly, there are many research works about the modification of the structure and performance of poly(aryl ketone). Following this research background, the poly(aryl imine ketone) has been proposed, which can be considered as being a hybrid structure of poly(aryl ether ketone)s, polyaramides and polyaniline. Consequently, it has excellent combination property, such as:good dissolving capacity, easy modification of structure and good heat-resistant quality. Additionally, the preparative cost of this polymer is cheap. For these reasons, the poly(aryl imine ketone) has the potential application prospect in the fabrication of the target materials for the laser inertial confinement fusion experiments(ICF).In this paper, six kinds different poly(aryl imine ketone) structures are designed, which are the poly(aryl imine ketone), poly(aryl imine imine ketone), poly(aryl imine ketone ketone), poly(aryl imine imine ketone ketone), Fluorene-poly(aryl imine imine ketone), Naphthyl-poly(aryl imine imine ketone). By the Materials Studio software of Accelrys company, the characteristics of single chain and aggregation structure of these polymers are simulated, such as glass transition, mechanical property, and so on. Simulated results indicate that there are different structural parameters in polymer chains and macroparameters in aggregation structures when it has different ratio of carbonyl and imine in polymer structures. As the ratio of carbonyl and imine raises from 1/2 to 2/1, the bond length, dihedral angel and atomic charge distribution of polymer chains reduce, but bond order series is rising. These changes result in higher bulk density, higher solubility parameter, superior thermal property and mechanical property in the polymer structures with high ratio of carbonyl and imine.Contrasting the simulated results of poly(aryl imine ketone) and poly(aryl imine imine ketone ketone), in which structures there has the same ratio of carbonyl and imine, it is found that there has few effects on macroparameters of polymers, such as solubility parameter, thermal property and mechanical property, when array order of carbonyl and imine is changed. However, the shorter bond length, uniform distribution charge density and lower dipole moment in the structure of poly(aryl imine ketone) promote higher bulk density and total molecular energy.Simulated results of poly(aryl imine imine ketone), Fluorene-poly(aryl imine imine ketone) and Naphthyl-poly(aryl imine imine ketone) indicate that the introduction of big conformation affects the structural parameters and macroparameters obviously. Because of delocalized molecular structure of naphthyl and as the part of main chain, Naphthyl-poly(aryl imine imine ketone) has the uniform distribution charge density, lower dipole moment and lower glass temperature comparing with poly(aryl imine imine ketone). However, there has few improvements in dissolubility and mechanical property introducing the naphthyl to poly(aryl imine imine ketone) structure. In spite of rigid planar structure of fluorene, it is suspended out of the main chain of Fluorene-poly(aryl imine imine ketone) structure, therfore it is as a functional side chain. Presenting of the functional side chain, the interaction among the polymer chains is reduced, which lower the solubility parameter of polymer. At the same time, the functional side chain limit the movement of molecular chain, and improve the glass temperature and mechanical property. Because of the photism of fluorene, the Fluorene-poly(aryl imine imine ketone) has the uniform distribution charge density and lower dipole moment.With the Buchwald-Hartwig cross coupling polycondensation, poly(aryl imine ketone), poly(aryl imine imine ketone), poly(aryl imine imine ketone ketone), Fluorene-poly(aryl imine imine ketone) and meta-position structure polymers are synthesized. By the Friedel-Crafts reaction and sulfur reduction method, polymerization monomers are synthesized, such as bis(4-bromophenyl)methanone, 1,4-phenylenebis((4-bromophenyl) methanone), 1,3-phenylenebis((4-bromophenyl) methanone), 1,3,5-phenylenetri((4-bromo-phenyl) methanone), (4-aminophenyl)(4-bromophenyl) methanone, which structures are characterized by FT-IR,1H-NMR and MS. Based on the discussion of catalytic and reaction conditions, the optimal polymerization reaction conditions are obtained, which are that catalytic system is Pd2(dba)3/BINAP, palladium catalyst concentration is 0.005mol/L, the reaction temperature is about 180℃, the step heat up is favor of improvement of molecular weight, the reaction solvent is DMAc, and the monomer concentration is about 0.5mol/L. Using these conditions, the different polymers are prepared, which structures are characterized by FT-IR,1H-NMR,elementary analysis and XRD, and which thermal performances are characterized by thermal analyzer. The characterization results shows that these polymers have the amorphousness structure, which glass temperature is more than 150℃, and thermal decomposition temperature is more than 420℃The dissolubility analysis indicates that these polymers can be easily dissolved in polarity aprotic solvent, such as DMF, DMAc, NMP, and so on.Using monomers with ether bond, sulphone bond and tribromo arylketone, the modification polymers are obtained, which are the poly(aryl ether imine ketone), poly(aryl sulphone imine ketone) and poly (aryl imine ketone) with super molecular structure. The characterization results indicate that it can improve the solubility of polymers and reduce the glass temperature of polymers by introducing the ether bond and sulphone bond. And the poly (aryl imine ketone) with super molecular structure has the three-dimensional cubicd structure, which contains porous sizes of 32nm.The poly(aryl imine imine ketone) has the excellent combination property proved by computer simulation and experiment data, and moreover, it has the cheap prepared cost and higher productive rate. Therefore it has been used to fabricate the target materials for the ICF experiments in this paper. Firstly, the low density poly(aryl imine imine ketone) foams are fabricated by thermal induce phase separation and freeze-drying technology. By the material studio software, phase separation process is ananlysized theoretically, the phase separation diagram of poly(aryl imine imine ketone) and dioxane is obtained, and relationship of molecular weight versus critical intersolubility concentration and critical intersolubility temperature of polymer solution is ananlysized theoretically. Based on the theory support and experiment control condition, the low density foams are fabricated, which have the density of 80mg/cm3-300mg/cm3, average porous sizes is less than 5μm, and thermal arrest temperature of sizes is about 250℃. Furthermore, the foams have the enough strength to meet the request of following treatment.Secondly, the highly spherical millimeter-sized poly(aryl imine imine ketone) is fabricated by microfluid technology and double emulsion technology. The control conditions of wall thickness and diameter of capsules and effect factors on quality of capsules are discussed. And then, the capsules are fabricated, which have the diameter of 0.6-2mm, wall thickness of 5-20μm, and thermal arrest temperature of sizes is from-190℃to 250℃. The morphology characterization indicates that there have different structure between out side and inside of capsule, which results from different phase separation process when the solvent departs from polymer solution. In the same fabrication batch, diameter monodispersity of capsules is more than 88% in the range of±5% capsules diameter, and degree of sphericity of capsules is more than 94%.
