摘要:
在去离子水溶液中以甲基三甲氧基硅烷作为反应单体,通过水解-缩聚两步法合成了亚微米级聚倍半硅氧烷微球。考察了去离子水的电导率和单体pH值对水解反应时间、聚合成球时间和微球粒径的影响,以及单体氯离子含量对微球表面洁净度的影响。通过扫描电子显微镜、粒度分布测试、傅里叶变换红外光谱及热重分析对所制备微球的形貌、粒径分布、有机功能基及热性能进行了分析表征。结果表明,在去离子水电导率小于15 μS/cm、单体pH值为4~5以及单体氯离子含量小于0.023 mg/L的条件下,有利于制得亚微米级的高洁净度聚倍半硅氧烷微球。
Abstract:
The submicron sized polysilsesquio-xane microspheres were synthesized by hydrolysis and polycondensation two-step method using methyltri-methoxysilane as reaction monomer in deionized water solution. The effects of conductivity of deionized water and pH value of monomer on hydrolysis time, polymerization time, and particle size of microsphere were investigated, as well as the effect of chloride ion content in monomer on surface cleanliness of microspheres. The morphology, particle size distribution, organic functional groups and thermal properties of the microspheres were analyzed and characterized by scanning electron microscopy, particle size distribution testing, Fourier transform infrared spectroscopy and thermogravimetric analysis. The results showed that under the conditions of deionized water conductivity less than 15 μS/cm, pH value of monomer 4-5 and chloride ion content in monomer less than 0.023 mg/L, it was favorable for preparation of submicron polysilsesquioxane microspheres with high level cleanliness .
