Effects of fluorine atoms on structure and surface properties of PANI and fluorinated PANI/GPTMS hybrid films
Source abstract
Abstract
Fluorinated PANI/GPTMS hybrid films were successfully prepared from different polyfluoroaniline emulsions and γ-glycidoxypropyltrimethoxysilane (GPTMS) via a sol–gel method. Fluorinated PANI emulsion was generated via a chemical method in an acidic medium using 3-fluoroaniline (F1ANI) and 3,5-bis(trifluoromethyl)aniline (F6ANI) as monomer, respectively. The experimental results demonstrated that due to the presence of electron-withdrawing group, the introduction of fluorine atoms in polyaniline backbone can reduce the size of PANI particles and the interaction between inorganic sol and fluorinated PANI. A comparison indicated that the water repellency and thermal stability of the PF1ANI/GPTMS hybrid films were lower than those of the PF6ANI/GPTMS hybrid films, but its corrosion-protective ability was higher than those of the latter. Structures of PANI (a), PF1ANI (b), PF6ANI (c), and PANI/GPTMS hybrids (d).
