High-specific-capacitance carbonized degummed silk and preparation method thereof

The invention provides high-specific-capacitance carbonized degummed silk. The high-specific-capacitance carbonized degummed silk is obtained by degumming and carbonizing modified silk. The modified silk is formed by solidifying silk liquid secreted when matured silkworms cocoon after silkworm feeding ammonium molybdate or sodium molybdate. The specific capacitance of the carbonized degummed silk is greatly improved, so that the carbonized degummed silk has the potential of being applied to electrodes of flexible energy storage devices (such as capacitors, electrode plates, batteries and the like). The preparation method of the high-specific-capacitance carbonized degummed silk is easy to operate and suitable for large-scale industrial production. 本发明提供了一种高比电容碳化脱胶蚕丝，将改性蚕丝脱胶后碳化处理获得。所述改性蚕丝是蚕食用钼酸铵或钼酸钠后形成熟蚕结茧时所分泌丝液凝固而成的蚕丝。本发明极大地提高了碳化脱胶蚕丝的比电容，使得其具有应用于柔性储能器件（如电容器、电极片、电池等）电极的潜能。本发明涉及的高比电容碳化脱胶蚕丝制备方法操作简单、适合大规模工业化生产。
