摘要
选用紫外光引发剂,利用点击反应将聚乙二醇(Mn;2000)双丙烯酸酯(polyethylene glycol 2000 diacrylate,PEGDA-2000)以及N-乙烯基吡咯烷酮(N-Vinyl-2-pyrrolidone,NVP)接枝到POSS-SH,方便快速的制备了无色透明的高弹态的交联体聚合物薄膜。此聚合物薄膜对某些溶剂具有一定的吸液性能,并计算了其吸液率和吸液速率;其热稳定性T_(d5%)达到300℃;此聚合物是一个疏水亲油型薄膜,在中性和酸性环境下具有更好的稳定性和耐久性;制备的疏水亲油型复合滤布的油品通量的临界点出现在17 s,此时油水混合物的临界点前的平均油品通量为15651 L/m^(2)h,分离效率达到了96%。
A colorless and transparent crosslinked polymer film with high elastic state is quickly prepared by polyethylene glycol 2000 diacrylate(PEGDA-2000)and N-vinyl-2-pyrrolidone(NVP)onto POSS-SH via click reaction using UV initiator.The polymer film has certain absorbability for some solvents,and its absorbability rate are calculated.Its thermal stability T_(d5%) reaches 300℃.The polymer is a hydrophobic and oil-philic film with better stability and durability in neutral and acidic environments.The critical point of oil flux of the hydrophobic and oil-philic composite press cloth appears at 17 s,at which the average oil flux before the critical point of oil-water mixture is 15651 L/(m^(2)·h),and the separation efficiency reaches 96%.
