采用氧化剂和溶菌酶对聚吡咯（PPy）进行修饰，制备了聚吡咯@溶菌酶（PPy@LZM）生物质杂化膜和自支撑膜。初步探索了制备导电性能最佳的聚吡咯薄膜的最佳工艺参数。Ca的最高电导率。6.13以30 mmol/L（9 mL）的过硫酸铵为氧化剂，65 μL吡咯为引发剂，聚合12 h，可得到S/m。在此基础上，制备了一系列电导率稳定的聚吡咯@LZM。并对复合材料的体相结构、形貌、热性能和粘接性能进行了研究。结果表明，LZM的加入可以提高PPy薄膜的热性能和附着力，而对PPy薄膜的化学结构和电导率影响不大。此外，PPy@LZM杂化材料具有最佳的导电性能，如电导率约为100%. 2.23 S/m，ca的热阻。当溶菌酶含量为0.45 mL，聚合时间为18 h时，聚合物对塑料的粘附性最好。
An assembly approach to modify polypyrrole (PPy) with oxidant and lysozyme to prepare polypyrrole@lysozyme (PPy@LZM) biomass hybrid and free-standing film is reported. The optimal parameters for preparing PPy film with best conductivity were investigated primarily. The highest conductivity of ca. 6.13 S/m can be obtained with the 30 mmol/L (9 mL) of ammonium persulfate as oxidant, and polymerization with 65 μL pyrrole for 12 h. And then, a series of PPy@LZM were prepared with stable conductivity. The bulk structure, morphology, thermal properties and adhesion were investigated further. It is found that the LZM may increase the thermal properties and adhesion of the PPy film with little influence on the chemical structure and conductivity. Moreover, the PPy@LZM hybrid present the optimum performance, such as the conductivity of ca. 2.23 S/m, thermal resistance of ca. 180 °C, and significant adhesion to plastic with the lysozyme content of 0.45 mL and polymerization time of 18 h.
