Dodecylbenzene 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 k Omega/square and visible light transmittance is higher than 75%. POLYM. ENG. SCI., 50:986-990, 2010.
