摘要: As one of the strongest and oldest natural fibers, ramie fiber has been widely used for fabric production at least six thousand years. And degumming is a critical procedure that developed to hold fiber’s shape, reduce wrinkling, introduce silky luster appearance. Herein, we fundamentally new working principle into field by using triboelectric effect. Resort water-driven nanogenerator (WD-TENG), fibers efficiency was greatly enhanced with improved quality, including both surface morphology mechanical properties. Furthermore, it saves chemicals usage in traditional method, which makes green practical approach fully remove noncellulosic compositions from fibers. In addition, as systematical study, WD-TENG further employed sustainable power source electrochemically degrade wastewater recycling kinetic energy flowing self-powered manner. Under fixed current output 3.5 mA voltage 10 V, cleaning system capable up 90% pollutants 120 min. Given compelling features being self-powered, environmentally friendly, extremely cost-effective, good stability, high degradation efficiency, presented work renders an innovative extraction, could be adopted technology textile industry.
