Abstract

八氨丙基齐聚倍半硅氧烷（POSS-NH2）是以立方结构Si-O-Si为核、顶角的8个氨丙基为壳的有机无机杂化纳米粒子,其粒径大小与大分子链的尺度相当.羧甲基纤维素（CMC）凭借其可再生性、可生物降解性、生物相容性和水溶性成为水凝胶制备的首选材料.本研究利用POSS-NH2中的NH2基团和CMC中的COOH基团之间的氢键作用形成POSS-CMC嵌段共聚物,继而由于POSS纳米粒子的聚集而交联形成新型的POSS/CMC水凝胶.并在此基础上,设计制备了双网络POSS/CMC/PNIPAm杂化水凝胶.通过红外光谱、原子力显微镜（AFM）、扫描电子显微镜（SEM）、流变仪等测试手段分别对所制的POSS纳米粒子、POSS/CMC和POSS/CMC/PNIPAm水凝胶的结构和性能进行了表征.结果表明,所制备的八氨基POSS纳米粒子的粒径为4 nm,并成功制备了双网络POSS/CMC/PNIPAm杂化水凝胶,并且其具有优异机械性能、较好的溶胀性能和快速的温度响应性.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
