Thus, it renders PTFE and Si surface conductive.4-VAn is coupled with hydrogen terminated Si surfaces for electroless metal and synthetic metal deposition.Palladium(II) schiff base complexes derived from Allylamine and vinylaniline has been reported. It also acts as a second surfactant for coating nanomagnetic particles. It is used in functionalization of single-walled carbon nanotube through solvent free functionalization. General description 4-Vinylaniline is a vinyl-substituted aromatic amine that is widely used as a crosslinking agent in the production of resins, adhesives, and coatings, enhancing their mechanical properties and chemical resistance. It can be polymerized by methods like radical polymerization, cationic polymerization, or oxidative polymerization to form poly(4-vinylaniline) or P4VA. 4- Vinylaniline can be selectively polymerized or chemically modified to respond to specific analytes or stimuli, allowing the development of conductive polymers for biosensors. Application 4-Vinylaniline can be used as: A monomer to prepare electrically conductive polyvinylaniline/polyaniline (PVAN/PANI) bilayer for surface modification of bacterial cellulose (BC) nanofibril network. This material can be utilized as an electrochemical biosensor for nerve regenerative medicine. To functionalize carbon nanodots for in vivo fluorometric biosensors, for the detection of mercury and cysteine. As a precursor to prepare conductive and biocompatible hydrogels forwound healing applications.
