Fabrication of Novel Transparent Inorganic Polymer Derived Microchannels and Application for Photopolymerization

Abstract

The present work describes fabrication of novel inorganic microfluidic channels derived from commercially available inorganic polymer allylhydridopolycarbosi lane (AHPCS) by UV imprinting lithography process. The UV transparency and solvent resistance of the microfluidic channels was measured when the polymer was cured at various conditions. The microchannel cured at 160 degrees C for 3 h showed excellent transparency, especially in visible region. The photopolymerization of trimethylolpropanetriacrylate (TMPTA) in the microchannel resulted in greater yield and 20 times faster reaction than that in batch process. These preliminary results demonstrated that novel AHPCS derived microchannel can be useful as an alternative platform for optical and photochemical microfluidic devices.
