Synthesis and characterization of monodisperse PSMMA@ZrO2 core-shell particles and ZrO2 hollow particles

采用乙腈与乙醇混合溶剂法制备出单分散的PSMMA@ZrO2核壳胶体颗粒,并通过TEM、SEM等表征手段对乙腈相对含量以及催化剂选择等参数的影响进行研究,结果表明室温下乙腈相对体积含量为20%时,采用去离子水为催化剂可制得高质量的单分散核壳胶体颗粒.通过高温煅烧得到ZrO2中空球,XRD结果表明二氧化锆转化为单斜相.漫反射光谱结果表明ZrO2核壳颗粒与中空颗粒在测量光谱区间内均具有较高的反射率.
