摘要
文章以皮芯结构的聚丙烯/聚乙烯(PP/PE)双组份纤维为原料,通过亲水整理、梳理成网和针刺加固工艺制备了具有一定强力的非织造材料,经超声分散、喷涂、高温热处理将多壁碳纳米管(MWCNTs)负载于非织造材料表面形成非织造光热转化材料,对所得材料进行结构和太阳能水蒸发应用性能测试与分析。结果表明:高温处理后MWCNTs在非织造材料上的附着牢度大幅度提升,制得的非织造光热转化材料在1个模拟太阳下分别可以实现1.31 kg·m^(-2)·h^(-1)的蒸发速率和87.5%的光热转化效率,具有较强的光热性能。
In this paper,polypropylene/polyethylene(PP/PE)bicomponent fiber was firstly selected as a raw material to prepare the hydrophilic nonwovens with competitive strength through hydrophilic finishing,carding and needle punching process.Secondly,the multi-wall carbon nanotubes(MWCNTs)were dispersed in ethanol and sprayed on the surface of nonwoven,following with high temperature thermal treatment.Finally,the structural features and solar water evaporation performances of the photothermal nonwoven were tested and analyzed.The results showed that the adhesion fastness of MWCNTs to nonwovens was greatly improved after high temperature treatment,and the hydrophilic nonwovens exhibited strong photothermal conversion ability,with the evaporation rate of 1.31 kg·m-2·h-1 and the photothermal conversion efficiency of 87.5%in the solar vapor generation under 1 simulated sun.
