Application Of Dynamic Rheology Model In The Multicomponent Composites Based On Polyarylene Ether Nitrile

For the materials to be used in the microelectronics industry, they should have good thermal conductivity, electric insulating, easy processability and corrosion resistance due to the high density and integrity of electronic devices. The traditional inorganic materials are disadvantageous, while the polymer based composites, especially for the special polymers, have witnessed increasing research interests in the electronic industry. Moreover, the simple or single component material hardly meet the requirements of various real applications, thus the composite materials which combine the multifunction of various material component are widely employed, such as polymer blending/copolymerization or introducing inorganic functional nanomaterials into polymer matrix. Generally, the interfacial compatibility between different polymer resin or polymer matrix and fillers plays a very important role in determining the overall performance of final composites. Therefore, it is essential to characterize the interfacial compatibility of polymer based composites in order to optimize the performance.In this thesis, the interfacial compatibility of polyarylene ether nitrile based composites is systematically analyzed. On the basis of various dynamic rheology models, this thesis focuses on the interfacial compatibility analysis of polyarylene ether nitrile blending and polyarylene ether nitrile/multiwall carbon nanotubes composites. The main contents are as follows:1. The history of dynamic polymer rheology is briefly introduced, especially for the basic model of dynamic rheology model and their applications in the evaluation of polymer composites interfacial compatibility.2. The polyarylene ether nitrile blending films are fabricated; their chemical compositions, structures, morphology and thermal, mechanical, electric properties are systematically characterized.3. The aromatic nitrile functionalized multiwall carbon nanotubes are obtained by grafting amino phthalonitrile onto the surface of multiwall carbon nanotubes, the polyarylene ether nitrile/multiwall carbon nanotubes composites films with good interfacial compatibility are fabricated. The FTIR, thermal analysis techniques, scanning electron microscopy, universal testing machine and dielectric testing have been employed to characterize the composites, structures and properties of polymer composite films. Finally, the dynamic rheology testing is conducted for composites films with different loading content of carbon nanotubes, and good match between the experimental results and theoretic simulations.
