受荷叶自清洁效应启发的手术服表面改性与防污染性能
Inspired by Self-cleaning Effect of Lotus Leaf:Surface Modification and Antifouling Performance with Surgical Clothing
摘要
Abstract
To improve medical protective performance of current commercial surgical clothing under special medical operating conditions and decrease the cross-infection risk of medical personnel and patient due to contacting blood and body fluids carrying pathogens. Inspired by self-cleaning effect of lotus leaf, superhydrophobic/superoleophobic technology is used to modify the commercial surgical clothing surface with fluorine-containing amphiphobic solution for improving its anti-fouling (waterproof, oil-proof, and anti-blood) performance. Scanning electron microscopy and element analysis characterizations verify that the fluorinecontaining polymer is fixed on the surgical clothing surface. The waterproof, oil-proof, and anti-blood pollution performances of the modified surgical clothing are conducted, and the results show that the water contact angle of modified surgical clothing surface reaches to (138 ± 2) °, meanwhile the roll angle decreases to 4. 0°, indicating the obvious improvement of waterproof performance. Additionally, modified surgical clothing is hard to be wetted by oil droplet for at least 60 seconds. And it allows blood droplet quickly rolling off modified surgical clothing surface by tilting the surface to 20. 6° showing low adhesion characteristic to blood droplet.Meanwhile, it keeps excellent water vapor permeability (7. 90 g/ (min·m2)) .关键词
