Abstract
AbstractDodecylbenzene sulfonic acid‐doped polyaniline (DBSA‐PANI) was prepared with 3‐glycidoxypropyltrimethoxysilane (GPTMS) through a sol–gel route without water and ethanol. Acetic acid was used to play both the roles of reagent and catalyst during the hydrolysis‐condensation reaction of GPTMS, which affected the structure of precursors. On the other hand, m‐cresol can adjust the acidity of solution and it was also a secondary dopant in DBSA‐PANI to enhance conductivity of hybrid films. The conductivity and visible light transmittance vary with the molar ratio of acetic acid to GPTMS and m‐cresol to GPTMS. Sheet resistance of the new hybrid films made by a dipping process reaches 5.1 kΩ/□ and visible light transmittance is higher than 75%. POLYM. ENG. SCI., 2010. © 2009 Society of Plastics Engineers
