PREPARATION AND PROPERTIES OF GEL POLYMER ELECTROLYTE BASED ON PVDF/ACRYLATE INTERPENETRATING POLYMER NETWORK FOR DYE-SENSITIZED SOLAR CELL

The gel polymer electrolytes（GPEs）based on poly（vinylidence fluoride）（PVDF）/acrylate interpenetrating polymer network（IPN）are prepared.The micro-phase separation type GPEs are characterized by Fourier transform infrared（FTIR）spectroscopy,scanning electron microscope（SEM）,respectively.Moreover,the conductivity and the voltage-current curves of the electrolytes are measured by electrochemical workstation.The higher porosity and electrolyte uptake are observed in the membranes prepared at lower crosslinker concentration.The suitable cross-linking acrylate monomer improves the porosity and the electrochemical behavior of GPE.A dye-sensitized solar cell（DSSC）employing PGE based on PVDF/poly（ethylene glycol dimethacrylate）（PEGDMA）IPN yields an open-circuit voltage of 0.674 V,short-circuit current of 8.476 mA·cm-2and the conversion efficiency of 2.710% under 100 mW·cm-2illumination.

浅析悬浮PTFE相对分子质量的影响因素--基于Ploymer plus

通过Ploymer plus对PTFE悬浮聚合过程进行模拟分析,结果表明:升高反应温度,聚合物的相对分子质量降低;在一定的压力范围内,反应压力的变化对聚合物的相对分子质量没有明显影响;增加引发剂的加入量,聚合物的相对分子质量减小;引发剂分步加入,聚合物的相对分子质量增加;反应介质的pH、搅拌速率等因素对聚合物的相对分子质量也有一定程度的影响。
