| 摘 要： | 用苯酚和甲醛在碱性条件下合成了可溶性酚醛树脂,加入一定质量比的单质硫,在氮气气氛下进行热裂解,制备了硫化聚并苯导电材料(SPAS);用FTIR、XRD、TG、SEM、BET等方法对所制备材料进行了结构表征,用标准四探针方法对裂解产物的室温电导率进行了测定.研究结果表明:掺杂硫的酚醛树脂经裂解后,产物呈现无定形结构且材料的层间距增大,裂解产物的比表面积比未硫化的裂解产物的比表面积增大,当硫的掺杂量为10%时,裂解产物的比表面积达140m2/g,电导率可达2～4S/cm;电化学性能测试结果表明,硫化后的裂解产物的首次放电容量和首次充放电效率都明显提高,当硫的掺杂量为10%时,首次放电容量达1410mAh/g,首次充放电效率达85.5%,比未硫化的聚并苯电池的首次充放电效率提高10%.
