| Four series (including 29 species) of macroporous polydivinylbenzene (PDVB) microspheres were prepared by suspension polymerization in the presence of 7 types of organic compounds as porogens or 3 series of polymer and organic compound composites as co-porogens. The microspheres were analyzed by N2 sorption, Hg intrusion and SEM. It was found that the better compatibility between porogen and PDVB network resulted late phase separation and consequently, higher specific surface area and porosity. PDVB microspheres with different pore structure could be controllably prepared by changing porogen type when organic compounds were used as porogens. The specific surface area, the pore area, and the total pore volume of PDVB microspheres could be controlled in the range of 482～818 m2/g, 53～169 m2/g, and 0.41～2.02 m3/g, respectively. Likewise, when composites of polymer and organic compound were used as co-porogens, pore structure of PDVB microspheres could be tuned by varying polymer level in co-porogens. The specific surface area, the pore area, and the total pore volume could be tuned in the range of 224～813 m2/g, 42～177 m2/g, and 0.18～0.89 m3/g, respectively. Suitable polymer concentration co-porogen could induce double phase separation, which formed good pore connectivity in PDVB microspheres. This kind of PDVB microspheres had potential application in storage materials for inertial confinement fusion and adsorbents.Hyper-cross-linked polystyrene (HCLPS) microspheres (including 7 species) with definite pore structure and bimodal pore size distribution were synthesized by suspension polymerization and post cross-linking. The products were characterized by N2 sorption, Hg intrusion, and SEM. It was found that HCLPS microspheres with controllable pore structure could be prepared by changing polypropylene (PP) concentration in toluene. The specific surface area, the pore area, and the total pore volume of HCLPS microspheres could be controlled in the range of 389～793 m2/g, 49～112 m2/g, and 0.27～0.59 m3/g, respectively. HCLPS microspheres with bimodal pore size distribution were successfully prepared by two cross-linking route. Furthermore, bimodal characteristic became more obvious with increasing PP level in toluene. HCLPS microspheres with bimodal pore size distribution have good application prospect in the field of catalyst supports.HCLPS microspheres with ultra-high specific surface area were generated by dispersion polymerization and post cross-linking. The microspheres were analyzed by N2 sorption, and TEM. The results illuminated that pore structure of HCLPS microspheres could be tuned by changing vinylbenzyl chloride concentration in monomer mixtures. The specific surface area, and the total pore volume of HCLPS microspheres could be controlled in the range of 17～1161 m2/g, and 0.01～0.72 m3/g, respectively. In addition, HCLPS microspheres with ultra-high specific surface area were explored for hydrogen storage media. It was found that HCLPS microspheres exhibited high hydrogen storage capacity (2.27 wt%) at 1.5MPa/163K. A series of magnetic porous microspheres (MPMs) were fabricated with sulfonated macroporous PDVB as a template. The products were analyzed by FT-IR, TEM, TGA, XRD and magnetometer, respectively. The results demonstrated that the weight fraction of magnetic nanoparticles in MPMs could be tuned from 4～20 wt%, and MPMs exhibited superparamagnetic property at room temperature. The applicability of MPMs for removal of cationic dyes from wastewater was also explored. The results demonstrated that cationic dyes could be quickly adsorbed into MPMs, and the maximum adsorption efficiency reached 99.2%. MPMs could be instantly separated from wastewater under an external magnetic field. Moreover, MPMs had a simple regeneration process and could be re-used for at least 30 times. Therefore, a novel recyclable adsorbent was explored for fast treatment of cationic dyes from wastewater.
