During the outbreak of COVID-19, the fogging of goggles was a fatal problem for doctors. At present, there are many ways to prevent fogging by adjusting surface wettability. However, the mechanical properties of most super-hydrophilic antifogging coatings are poor, easy to lose their antifogging properties when encountering fingers or cloth friction. To address this issue, the Konjac Glucomannan was cross-linked with water-soluble silicone fluid to form a binder, then being combined with the modified Ecokimera to prepare an eco-friendly super-hydrophilic coating that possessed excellent super-hydrophilicity, and the water contact angle (WCA) was 2.51 ± 1°. In addition, the WCA is still about 5° after 180 times of antifogging tests. The friction resistance of the coating was as high as 24 m. Moreover, the light transmittance was only reduced by 3%. Besides, they also had the excellent self-cleaning property. After being stored in the laboratory environment for 90 days, it can still maintain the hydrophilic property (WCA is about 5°). In general, the method proposed in this study is low-cost and eco-friendly, and can be widely used in the preparation of antifogging coatings.

在 COVID-19 爆发期间，护目镜起雾对医生来说是一个致命的问题。目前，通过调节表面润湿性来防止起雾的方法有很多。然而，大多数超亲水防雾涂料的机械性能较差，遇到手指或布料摩擦时容易失去防雾性能。针对这一问题，将魔芋葡甘露聚糖与水溶性硅油交联形成粘合剂，再与改性后的Ecokimera结合制备出具有优异超亲水性的环保型超亲水涂料，水接触角 (WCA) 为 2.51 ± 1°。此外，经过180次防雾测试后，WCA仍在5°左右。涂层的摩擦阻力高达24 m。此外，透光率仅降低了3%。此外，它们还具有出色的自清洁性能。在实验室环境中存放90天后，仍能保持亲水性（WCA约为5°）。总的来说，本研究提出的方法成本低、环境友好，可广泛用于防雾涂料的制备。
