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

摘要:

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量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。并考察了BPEAS、MAn-BPEAS及其超分子乳液在棉织物上的应用性能。

Abstract:

Carboxyl-modified block amino silicone polyether (MAn-BPEAS) was prepared using block amino silicone polyether (BPEAS) and Maleic anhydride (MAn). Chemical structure of MAn-BPEAS was characterized by IR. Then, MAn-BPEAS and BPEAS was emulsified with nonionic surfactant isomeric alcohol ethoxylates (XL) in order to achieve a translucent MAn-BPEAS and BPEAS microemulsion. The supramolecular emulsion (BPEAS/MAn-BPEAS) was got by mixing equal 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-assembled was measured by Nano-particle surface potential analyzer. Then, the obtained supramolecular emulsion was applied on cotton fabric, and the fabric surface film morphologies observed by scanning electron microscopy(SEM). The applied performance of BPEAS、MAn-BPEAS and BPEAS/MAn-BPEAS emulsion was investigated.
