双亲性水凝胶微球模板法合成PAM/CaCO_3有机-无机复合微球

Synthesis of PAM/CaCO_3 inorganic-organic composite microspheres by template methods of amphiphilic hydrogel microspheres

本文采用以不同链长的溴代烷对反相悬浮聚合法制备的,经表面烷基化修饰的PAM微球作为模板,通过外源沉积法制备具有核壳结构的PAM/CaCO_3有机-无机复合微球。利用SEM、FT-IR等对复合微球的形貌和组成进行表征。探讨了取代烷基链长、Ca^(2+)浓度、气体通入时间等条件对复合微球的形貌和组成产生的影响。

PAM microspheres were prepared by reverse suspension polymerization method as the template, modified by different bromoalkane, PAM/CaCO3 organic-inorganic composite microspheres with core-shell structure were prepared by external deposition method. The factors of the length of alkyl chain, concentration of Ca^2＋, time of the gas gone on the composite microspheres were studied. The morphology and composition of composite microspheres were characterized using SEM and FT-IR.
