Photocurable electrolytes were prepared by mixing proton conductive polymer sulfonated poly(ether ether ketone) (SPEEK), cross-linking monomer divinyl sulfone (DVS), photoinitiator phenylbis(2,4,6-trimethylbenzoyl)phosphineoxide (PI), dimethylacetamide (DMA), and ethanol. To investigate the proton transport property, a series of photocurable electrolytes with various PI content ratios were prepared to form photocured membranes. Water uptake, ion exchange capacity (IEC), proton conductivity, and water-resistance of the photocured membranes were investigated. Water-resistant photocured membrane is easy to prepare, which gives relatively high proton conductivity (28 mS cm^<-1> under 70 ℃ and relative humidity of 90 %). Patterning of micro-structure on the photocured membrane was also demonstrated by using the property of the photocurable electrolytes., identifier:https://dspace.jaist.ac.jp/dspace/handle/10119/10628

A study on via drilling and channel scribing on PEN and PET substrates for flexible electronic application is discussed in this paper. For the experiments, both KIF excimer laser (248 nm) and frequency tripled Nd:YAG (355 nm) laser are used. Different measurement techniques like optical microscopy, Dektak profilometer, Confocal microscopy and scanning electron microscopy (SEM) were employed to characterize the quality of the channels and vias. The patterned structures were filled by three different methods using a conductive paste or ink that is cured in an oven at an elevated temperature. The cross-sectional measurements of channels and vias were carried out using SEM to study the uniformity of filling.
