Abstract

Ag/fluorine-containing polyacrylate latex was successfully synthesized via Pickering emulsion polymerization using Ag/poly(2-dimethylaminoethyl methacrylate-co-hexafluorobutyl acrylate) (Ag/P(DMAEMA-co-HFBA)) hybrid micelles as particle emulsifiers. The influences of introducing the Ag nanoparticles (NPs) component and the concentration of Ag/P(DMAEMA-co-HFBA) hybrid micelles on emulsion polymerization and finished cotton fabric properties were studied. The results showed that the Ag/fluorine-containing polyacrylate latex had a higher conversion, smaller particle size than the fluorine-containing polyacrylate latex using P(DMAEMA-co-HFBA) micelles as emulsifiers, indicating the positive effect of Ag NPs on emulsion polymerization. And thermogravimetric analysis (TGA) proved that Ag NPs improved the thermal stability of the latex film. Moreover, the surface of the cotton fabric finished by Ag/fluorine-containing polyacrylate latex showed more rough morphology, better hydrophobicity and excellent antibacterial activity owing to the synergistic effect of the cationic fluorine-containing polyacrylate compounds and Ag nanoparticles. Meanwhile, the presence of Ag NPs also improved the tensile strength of the finished cotton fabric, but reduced slightly the whiteness. When the concentration of Ag/P(DMAEMA-co-HFBA) hybrid micelle emulsifier was 8 mg/mL, the Ag/fluorine-containing polyacrylate latex particles presented regular raspberry-shaped with an average diameter of 120 nm, and the water/oil contact angles of finished cotton fabric attained 145° and 90°, respectively. In addition, the finished cotton fabric exhibited excellent antibacterial properties against both S. aureus and E. coli as the concentration of Ag/P(DMAEMA-co-HFBA) hybrid micelles was 12 mg/mL. The mechanism for the formation of Ag/fluorine-containing polyacrylate latex was proposed.

Ag纳米粒子杂化两亲无规胶束稳定的Ag /含氟聚丙烯酸酯胶乳的皮克林乳液聚合合成及其在织物整理中的应用

摘要

聚丙烯酸酯胶乳的Ag /含氟经由皮克林乳液聚合用的Ag /聚(2-二甲氨基乙基甲基丙烯酸酯,成功地合成-hexafluorobutyl丙烯酸酯)银(Ag / P(DMAEMA--HFBA))混合胶束粒子乳化剂。研究了引入银纳米颗粒(NPs)组分和Ag / P(DMAEMA- co -HFBA)混合胶束的浓度对乳液聚合和棉织物最终性能的影响。结果表明,与使用P(DMAEMA- co的含氟聚丙烯酸酯乳胶相比,含银/氟聚丙烯酸酯乳胶具有更高的转化率,更小的粒径。-HFBA)作为乳化剂的胶束,表明Ag NPs对乳液聚合的积极作用。热重分析(TGA)证明银纳米颗粒提高了乳胶膜的热稳定性。而且,由于阳离子含氟聚丙烯酸酯化合物和Ag纳米颗粒的协同作用,用含银/含氟聚丙烯酸酯胶乳整理的棉织物表面表现出更粗糙的形态,更好的疏水性和优异的抗菌活性。同时,Ag NP的存在也改善了成品棉织物的抗张强度,但稍微降低了白度。当Ag / P(DMAEMA- co-HFBA)混合胶束乳化剂为8 mg / mL,含银/氟的聚丙烯酸酯乳胶颗粒呈规则的莓形,平均直径为120 nm,棉织物的水/油接触角分别为145°和90° °,分别。另外,由于Ag / P(DMAEMA- co - HFBA)杂化胶束的浓度为12mg / mL ,因此完成的棉织物对金黄色葡萄球菌和大肠杆菌均表现出优异的抗菌性能。提出了形成含银/氟聚丙烯酸酯胶乳的机理。
