Photopolymerization in dispersed systems

Dependence of the electro-optical properties of polymer dispersed liquid crystals on the photopolymerization process

We have studied the dependence of the electro-optical properties of polymer dispersed liquid crystals ~PDLC! on the ultraviolet ~UV! cure of the solution of monomer and liquid crystal. The kinetics of UV polymerization and its effect on the morphology of the phase separated droplets of liquid crystal determine the switching voltage, response time, and luminance of the PDLC. Using a series of st...

New Horizons in Cationic Photopolymerization

In this review, we report some recent advances and new horizons in UV-induced cationic photopolymerization. In particular, after a brief introduction on the discovery and affirmation of the cationic photopolymerization process, new efforts in the synthesis of cationic photoinitiators are reported. Subsequently, an interesting and absolutely new application is reported, related to the combinatio...

Ultra rapid prototyping of microfluidic systems using liquid phase photopolymerization.

We present a method for the ultra rapid prototyping of microfluidic systems using liquid phase photopolymerization, requiring less than 5 min from design to prototype. Microfluidic device fabrication is demonstrated in a universal plastic or glass cartridge. The method consists of the following steps: introduction of liquid prepolymer into the cartridge, UV exposure through a mask to define the...
