荧光太阳能聚光聚酰胺熔纺纤维的制备及其性能
Preparation and properties of melt-spun polyamide fiber for luminescent solar concentrators
摘要
Abstract
In order to obtain a new type of fiber-based luminescent solar concentrators(FLSCs)which can meet the requirements of textile processing by melt spinning method.FLSCs were pre-pared by melt spinning using biology base polyamide and high temperature fluorescent dyes.The effects of the type,concentration and drafting ratio of fluorescent dyes on their structure and properties were investigated.The results show that the FLSCs show a smooth surface and a uni-form evenness.The absorbance of the FLSCs increases with the increase of fluorescent dye con-centration.The excitation fluorescence intensity of FLSCs increases initially and then decreases.When the dye concentration is 0.2 wt％,the short-circuit current generated by the FLSCs cou-pling with polycrystalline solar panels reaches saturation,The current of introducing yellow fluo-rescent dye FLSCs can reach 10.2 μA.The absorbance and short-circuit current of 3 × drawn FLSCs are lower than those of as-spun FLSCs,while no significant change on the excitation fluo-rescence intensity of FLSCs.The tenacity values are all greater than 1.1 cN/dtex,which means the prepared FLSCs can meet the mechanical properties requirements of textile processing.关键词
