摘要：

为提高超滑织物的物理化学稳定性,首先采用乳液聚合法以乙烯基改性纳米二氧化硅(V-SiO2)为原料制备自黏性核壳型聚合物微球,将其经浸涂-焙烘工艺组装到棉织物表面得到粗糙基底;然后利用氨基-环氧基接枝反应、氨基-羟基氢键作用将氨基硅油接枝在粗糙基底表面得到超滑织物。探究了超滑织物的疏液、防污及物理化学稳定性能。结果表明:超滑织物中超滑表面的粗糙结构由粒径为321.3 nm的微球构成,表面水滴接触角为138°;水、二甲基亚砜在超滑织物表面的滑动角分别为7°、15°;接触番茄酱、咖啡污物后,超滑表面黏附量显著减少;经200 mL以内水冲击后,超滑织物表面水、二甲基亚砜的滑动角分别小于12°、26°;在pH值为3~9条件下其表面液滴的接触角稳定在42°~49°之间。

Abstract:

In order to improve the physical and chemical stability of super-slip(SLIPS) fabrics, the self-adhesive core-shell polymer microspheres were prepared by emulsion polymerization using vinyl-modified silica nanoparticles (V-SiO2) as the raw material. After the dipping and baking process, it was bonded to the surface of cotton fabric to obtain a rough substrate. The amino silicone oil was then grafted onto rough substrate surface by amino-epoxy graft reaction and amino-hydroxyl hydrogen bond to obtain a SLIPS-cotton fabric(SLIPS-Cotton). The properties of liquid repellent, antifouling, physical and chemical stability of SLIPS-Cotton were studied. The results shown that the rough structure of the SLIPS in SLIPS-Cotton is composed of microspheres with a particle size of 321.3 nm, and the contact angle of water droplets on the surface is 138°. The sliding angles of water and dimethyl sulfoxide on the surface of the SLIPS-Cotton are 7° and 15° respectively. After contacting with tomato sauce and coffee contaminants, the amount of adhesion on the surface of SLIPS-Cotton is significantly reduced. After water splash washing within 200 mL, the sliding angles of water and dimethyl sulfoxide on SLIPS-Cotton surface are less than 12° and 26°, respectively. The contact angles of droplets on the surface of the SLIPS-Cotton are stable between 42° and 49° at pH 3-9.

Key words: super-slip cotton fabric, emulsion polymerization, polymer microsphere, core-shell structure, liquid repellent and antifouling, antifouling performance
