Difunctional boron-containing reactive flame retardant for UV-curable epoxy acrylate oligomer was synthesized from phenyl boronic acid and glycidyl methacrylate. The synthesized reactive diluent was utilized to formulate ultraviolet (UV)-curable wood coatings. The weight fractions of reactive diluent in coatings formulation was varied from 5 to 25 wt % with constant photoinitiator concentration...

Research areas : Organic Electronics and Nano-fabrication-Our recent research theme is stretchable & patchable electronics based on polymeric substrates. Differ from other groups, we mainly deals with organic electronics by using UV-curable polymers as flexible substrates-We develop a novel fabrication technique for integrated organic devices on substrates with complex structure. Free-standing ...

Abstract We experimentally examined the time-evolutions of local compositions in photocurable, monomer-solvent-initiator ternary liquid film coatings using attenuated total-reflectance-Fourier transform infrared spectroscopy. The exhibited phase separation upon UV exposure owing to inherent partial miscibility between solvent and polymer. concentration at bottom coating increased when exposed l...

The evaluation of poly(limonene carbonate)s (PLCs), derived from orange oils and carbon dioxide, as UV-curable (powder) coating binders is described. PLCs with moderate molecular weight were prepared by copolymerization limonene oxide CO2 a subsequent reduction step transcarbonation 1,10-decanediol (1,10-DCD). These cured trifunctional thiol monomer in the presence photoinitiator via thiol-ene ...
