Biến tính một số loại vải dùng trong quân đội bằng các polyme methacrylat siêu kỵ nước

Abstract

Herein, the dyed and undyed cotton fabrics were modified with methacrylate to achieve superhydrophobicity. In this regard, two methacrylate copolymers, poly(GMA-co-LMA) and poly(GMA-co-3F) was first synthesized via radical copolymerization and then were used to coat onto these cotton fabric surfaces by immersion technique in the combination with heating at 140℃. The molecular weight of these resultant copolymers was 7.5 x 104 and 4.5 x 104 daltons respectively and the polymer dispersion index (PDI) was around 2. Under the Data physic’s OCA - 20ES device, the water contact angle of modified fabrics with poly(GMA-co-LMA) or with poly(GMA-co-3F) was in range 162°-165°, revealing the superhydrophobic of the resultant fabric. Compared to the as-prepared cotton fabrics, there were effectively no changes in color and breathability after modification, promoting the potential application in the apparel industry.
