Ultrasound Mediated Synthesis of Catalytic and Polymeric Materials

Polymer to diamond-like carbon. Synthesis of a carbon-based network polymer with an sp3 hybridized backbone which upon pyrolysis should yield a diamond-like carbon film. The rational design of an appropriate organic monomer and its polymerization to a network polymer whose weakest bond is between the sp3 hybridized backbone and the capping unit. Molecular weight was determined by GPC and laser light scattering experiments in addition to characterization of the polymer structure was carried out by solution and solid state NMR and is consistent with a quaternary backbone carbon bonded to a benzyl group. The decomposition profile for this polymer was established by TGA-MS. Pyrolysis shows the benzyl unit is the major bond to break in the polymer. Stabilization of the carbon backbone is under hot filament chemical vapor deposition conditions where atomic hydrogen stabilizes the growing diamond film.
