PLA@ZnO辐射制冷纤维膜制备与性能研究
Preparation and property research of PLA@ZnO radiation cooling fiber membrane
摘要
Abstract
In order to develop polylactic acid(PLA)based radiation cooling materials,PLA fiber membranes were prepared by electrospinning,then PLA@ZnO fiber membranes were obtained by chemical reaction method and direct deposition method.The fiber membrane morphology,chemical structure,mechanical property,hydrophilicity and radiation cooling property were studied.The results showed that compared to direct deposition,ZnO particles distribution on the surface of PLA@ZnO fiber prepared by chemical reaction was more even.As the increase of ZnO particles on the fiber surface,fiber surface was changed from hydrophobic to hydrophilic,and the stress of fiber membrane was reduced from 12.94 MPa to 7.85 MPa.After testing the outdoor radiation cooling effect of the fiber membrane,it was found that the solar average emissivity rate of the PLA@ZnO fiber membrane was 94.09%when the ZnCl2 content was 0.04 g,and the average reflectance rate was 81.91%.During the day when solar radiation was the strongest,temperature of the PLA@ZnO fiber membrane was lower 5℃than the temperature of the PLA fiber membrane,showing better radiation cooling effect.关键词
