In-situ photopolymerization synthesis and characterization of nanocomposite films obtained by using crosslinked acrylic based polymers and gold nanoparticles

Photopolymerization constitutes a significant portion polymer chemistry in terms of academic as well as industrial. In particular, with rapid room temperature curing, environmentally friendly and low cost characteristics their enhancement in such area involving coatings, adhesives, printing inks, microelectronic, fillings (teeth), bone biomaterial, tissue engineering and photo-optic control of polymeric material. In the past year, another subject that has gained importance is noble metal nanoparticles/polymer composites. They take part in optic, catalytic, sensor design, photoimmage and patterning and antimicrobial coatings especially du to the mechanical, optical and electronical properties. Selection of the polymers is of great importance for particle properties and final nanocomposite product. Conventional method using to prepare nanoparticle/polymer composites is physical dispersion of ready-prepared nanoparticles in the polymer matrix however, it doesn't always end up homogenous dispersion. Another approach is forming of polymer by dispersing inorganic nanoparticles in monomer system. The most sensitive and significant route is to obtain in situ noble metal nanoparticles simultanously with polymerization process and these plays a critical role on control and distrubition of particle size. By Sangermano and Yağcı, nanocomposite materials has been produced via free radical polymerization of acrylic formulations with noble metals such as gold and silver. The control of gold and silver nanoparticles size and shape haven't lost importance yet in the science environment, because certain controlled shape and size has significance in the processes involving optical, electronical and catalytic. Particularly due to the optical properties is connected to the particle shape, the presence of gold nanoparticles in composites enables final product to use in the field of bio/nano-medicine, sensor, catalytic and nanotechnology. Consequently, the aim of this project is to synthesize gold nanoparticles in reproducable size and shape by the means of photopolymerization techniques in situ and to determine the polymerization rate of the acquired crosslinked polymers with the means of RT-FTIR and Photo-DSC, furthermore research mopholPhotopolymerization constitutes a significant portion polymer chemistry in terms of academic as well as industrial.
