【摘要】 以甲基三乙氧基硅烷（MTES）为前驱体,γ-氨丙基三乙氧基硅烷（KH550）和马来酸酐（MA）制得羧基硅烷（CTES）为改性剂,氢氧化钠（NaOH）为催化剂,脂肪醇聚氧乙烯醚（AEO₃/AEO₉）为复合乳化剂,通过水解-缩合反应在水溶液中制得了一系列聚羧基/甲基倍半硅氧烷（PCMSQ）纳米杂化乳液.研究了乳化剂用量、催化剂浓度和油水比对PCMSQ纳米球平均粒径和微观形态的影响.用FTIR、XPS、DLS、SEM和TGA等对PCMSQ纳米球的结构、粒径、微观形态和耐热稳定性进行测定.结果表明,PCMSQ纳米球具有预期的结构和良好的耐热稳定性,且当w_{（AEO3/AEO9）}为0.36%⁰.54%,NaOH浓度为25⁵0mmol·L^-1和油水比为1∶10¹∶12时,制得的PCMSQ平均粒径介于100²00nm、大小均一,呈单分散性且球形度规整.更多还原

【Abstract】 A sort of Polycarboxyl/methylsilsesquioxane（PCMSQ）nano-hybrid emulsions were prepared via hydrolytic condensation method of methyltriethoxysilane（MTES）and carboxy silane（CTES）which was first fabricated byγ-aminopropyltriethoxysilane（KH550）with maleic anhydride（MA）,and sodium hydroxyl as the catalyst,primary alcobol ethoxylate（AEO₃/AEO₉）as mixed emulsifiers.Effects of the emulsifier doses,the catalyst concentration and the oil/water ratio were discussed.Structure,particle size,micromorphology and thermal stability of PCMSQ nanospheres were investigated by FTIR,XPS,DLS,SEM and TGA.Results indicated that structure of the PCMSQ was consistent with the expectant outcome and thermal stability of the PCMSQ nanospheres was excellent.When w_{（AEO3/AEO9）}is 0.36%⁰.54%,NaOH concentration is 25⁵0 mmol·L^-1 and oil/water ratio is 1∶10¹∶12,average particle sizes of the PCMSQ nanospheres were ranged of 100²00 nm.Meanwhile these PCMSQ nanospheres with the uniform average diameter and monodisperse,which were regularly spheres.更多还原
