聚硅氧烷超分子BPEAS/MAn-BPEAS的构筑及应用性能

Construction and Application Performance of Supramolecular BPEAS / MAn-BPEAS

以嵌段聚醚氨基硅(BPEAS)、马来酸酐为原料合成了羧基改性的嵌段聚醚氨基硅(MAn-BPEAS),用红外光谱(IR)对产物结构进行表征。用非离子表面活性剂异构醇聚氧乙烯醚(XL)将BPEAS与MAn-BPEAS乳化,制得外观半透明乳液。在自组装理论的指导下,将制得的乳液等质量混合进行静电自组装,得到超分子乳液。利用纳米粒度表面电位分析仪测定了自组装前后的乳液中胶束的粒径。将制得的超分子乳液应用于织物整理,并通过扫描电镜观察织物表面的膜形貌。考察了BPEAS、MAn-BPEAS及其超分子乳液在棉织物上的应用性能。

Carboxyl-modified block amino silicone polyether（MAn-BPEAS） was prepared using block amino silicone polyether （BPEAS） and Maleic anhydride （MAn） as raw materials. The chemical structure of MAn-BPEAS was characterized by means of IR. Then MAn-BPEAS and BPEAS were emulsified with nonionic surfactant isomeric alcohol ethoxylates （XL） in order to obtain a translucent MAn-BPEAS and BPEAS microemulsion. The supramolecular emulsion （BPEAS/MAn-BPEAS） was prepared by mixing equal mass of MAn-BPEAS and BPEAS microemulsion for electrostatic self- assembly under the guidance of the theory of self-assembly. The particle size of the emulsion micelles before and after the self-assembling was measured by Nano-particle surface potential analyzer. Then the obtained supramolecular emulsion was applied on cotton fabric, and the fabric surface film morphologies were observed by scanning electron microscopy （SEM）. The application performance of BPEAS, MAn- BPEAS and BPEAS/MAn-BPEAS emulsion was investigated.
