PLA基光热纳米纤维织物的制备及其光热性能
The preparation and properties of PLA-based photothermal nanofiber yarns and fabrics
摘要
Abstract
To address microplastic pollution and develop new seawater desalination materials,research was conducted on the preparation of photothermal micro-nano fiber yarns using PLA as the matrix material through conjugate electros-pinning technology.On this basis,PLA micro-nano fiber yarns with carbon black mass fractions of 0.8%,1.0%and 1.2%respectively were prepared and woven into 2 cm×4 cm PLA photothermal micro-nano fabrics with a warp and weft density of 7×12.The microstructure and properties of the prepared yarns and fabrics were comprehensively analyzed through characterization methods such as scanning electron microscopy,Fourier transform infrared spectrometer,and wa-ter contact Angle test.The results show that the concentration of carbon black within the range of 0.8%～1.0%has a sig-nificant effect on performance improvement,and the marginal benefit decreases when it exceeds 1.0%.The 1.2%carbon black fabric prepared can achieve a temperature rise of 66.4℃,an evaporation rate of 1.925 kg·m-2·h-1 and a photother-mal conversion efficiency of 95.24%under simulated sunlight,confirming its high-efficiency photothermal conversion characteristics.This research provides a new technical solution for the development of environmentally friendly seawa-ter desalination materials and simultaneously expands the application potential of degradable materials in the field of functional textiles.关键词
