通过原位乳液聚合制备了PANI-HCl/P(MMA-BA)导电复合材料,对其导电率进行测试,并用FTIR、STA、XPS对导电复合材料的结构、热学性能、掺杂率进行了表征。结果表明:当APS/ANI摩尔比为1:1.5、反应单体中ANI为33%时,导电复合材料中PANI表面掺杂率为37.56%,复合材料电导率达到1.472×103S/cm。FTIR谱图表明导电复合材料分子结构中存在C=O、N=Q=N、N-B-N等基团,说明共聚物P(MMA-BA)已经存在于复合材料中。STA测试结果表明:导电复合材料的玻璃化温度(Tg)为127℃,在270℃以下稳定性较好,通过原位乳液复合所得PANI-HCl/P(MMA-BA)导电复合材料的加工性及热稳定性能得到了改善。
PANI-HCl / P (MMA-BA) conductive composites were prepared by in-situ emulsion polymerization, and their conductivity was tested. The structure, thermal properties and doping rate of the conductive composites were characterized by FTIR, STA and XPS . The results show that the surface doping rate of PANI in the conductive composite is 37.56% when the molar ratio of APS / ANI is 1: 1.5 and the content of ANI is 33%. The conductivity of the composite reaches 1.472 × 103S / cm. The FTIR spectra show that there are C = O, N = Q = N, N-B-N and other groups in the molecular structure of the conductive composites, indicating that the copolymer P (MMA-BA) is already present in the composite. The results of STA test show that the glass transition temperature (Tg) of conductive composites is 127 ℃, and the stability is good under 270 ℃. The workability of PANI-HCl / P (MMA-BA) conductive composites And thermal stability has been improved.
