为提高超疏水锦纶织物的耐久性,以硬脂酸对蒙脱土(MMT)进行表面改性,再与聚二甲基硅氧烷(PDMS)混合制成分散液。采用浸涂法将分散液涂在锦纶织物表面,从而制得具有耐磨性的超疏水锦纶织物。使用红外光谱(FTIR)和扫描电镜(SEM)对织物化学成分以及表面形貌进行表征,并研究MMT与PDMS的质量比对锦纶织物疏水性能和耐磨性能的影响。试验结果显示,当MMT与PDMS的质量比为0.75∶1时,织物表面接触角最高,可达153.6°。该织物经砂纸摩擦55 cm后仍能保持超疏水性,显示出较好的耐摩擦性能。此外,该超疏水锦纶织物不仅具有良好的耐酸、耐弱碱及抗紫外线性能,还具有良好的自清洁性能。
Abstract:To enhance the durability of superhydrophobic nylon fabrics, montmorillonite(MMT) was modified with stearic acid and subsequently blended with polydimethylsiloxane(PDMS) to formulate a functional dispersion. The dispersion was applied to nylon fabric surfaces via dip-coating, producing abrasion-resistant superhydrophobic textiles. Fourier-transform infrared spectroscopy(FTIR) and scanning electron microscopy(SEM) were employed to analyze chemical compositions and surface morphologies. The influence of MMT/PDMS mass ratios on hydrophobicity and abrasion resistance was systematically investigated. Optimal performance was observed at a 0.75∶1 MMT/PDMS ratio, achieving a maximum contact angle of 153.6°. The modified fabric retained superhydrophobicity after 55 cm of sandpaper abrasion, demonstrating exceptional wear resistance. Additionally, the treated fabric exhibited acid resistance, weak alkali tolerance, UV stability, and effective self-cleaning properties.
