摘要
采用熔融共混挤出技术将高效率光热转化粉末材料铯钨青铜纳米颗粒(CsxWO3 NPs)均匀分散到聚酯切片中,制备光热转换聚酯母粒.将光热转换聚酯母粒与常规聚酯切片按一定比例进行共混,然后进行熔融和纺丝,制备得到0.5%CsxWO3易染色的高效光热转换聚酯纤维,分析该纤维的微观形貌、热稳定性、力学性能和发热性能.结果表明:CsxWO3 NPs的添加对纤维的热稳定性未产生明显影响,对纤维的力学性能有一定的提升;在1 kW/m2太阳光照强度照射下,光热转换聚酯纤维最高温度可达104.6℃,相比常规聚酯纤维提升约58.0℃.
Abstract
Using melt blending extrusion technology,efficient photothermal conversion powder cesium tungsten bronze nanoparticles(CsxWO3 NPs)were uniformly dispersed into polyester chips to prepare photothermal conversion polyester masterbatch.Blend photothermic conversion polyester masterbatch with conventional polyester chips in a specific ratio,followed by melting and spinning processes.0.5％CsxWO3 high-efficiency photothermal conversion polyester fibers with good dye-ability were prepared.The microstructure,thermal stability,mechanical properties and heating performance of the fiber were analyzed.The results showed that the addition of CsxWO3 NPs did not have a significant effect on the thermal stability of the fibers,but had a certain improvement in the mechanical properties of the fibers.Under the irradiation of 1 kW/m2 solar light intensity,the maximum temperature of the photothermal conversion polyester fiber reached 104.6℃,which was about 58.0℃higher than that of conventional polyester fibers.
