摘要
以棉纤维为原料,以柠檬酸、纯水、多聚磷酸铵、磷酸、硫酸为活化剂,采用碳化法制备了具有吸光发热功能的碳微粒,通过扫描电镜、红外光谱、吸光发热性能表征了活化剂类型对碳微粒结构及吸光发热性能的影响。结果表明:活化剂类型对碳微粒的微观形貌、红外吸收光谱曲线及吸光发热性能具有重要影响;碳微粒水溶液光照升温值随其红外光谱特征吸收峰相对强度的减小而升高;综合碳化收率和光照升温性能,多聚磷酸铵活化碳微粒性能较优,其涂层织物表现出良好的光照升温性能。
Carbon particles with light absorbing and heating properties are prepared by carbonization using cotton fiber as raw material and citric acid,pure water,ammonium polyphosphate,phosphoric acid,sulfuric acid as activators.Influences of activator type on the structure and the light absorbing and heating properties of carbon particles are studied by means of SEM,FTIR and light absorbing and heating properties.The results show that the activator type has an important effect on the micro-morphology,infrared absorption spectrum curve and light absorption and heating performance of carbon particles;The heating value of carbon particle aqueous solution under illumination increases with the decrease of the relative intensity of its infrared spectral characteristic absorption peak;Based on the comprehensive carbonization yield and light heating performance,ammonium polyphosphate activated carbon particles have better performance,and the coated fabrics exhibit good light heating performance.
