A hybrid material with a conductive organic network in an inorganic matrix has been prepared by in‐situ hydrolysis/polycondensation of TEOS in an aqueous solution of a solubilized polyaniline. Due to intense hydrogen bonding (indicated by 29 Si NMR and FTIR) the conductive polymer is very well dispersed in the silica matrix. The Figure shows SEM images of a 46/54 wt.‐% hybrid at two temperatures (left 20 °C, right 100 °C).
