Abstract:	摘要： Highly stretchable conductive materials provide unique advantages for flexible electronics and many other advanced fields. In this study, we create an elastic porous polydimethylsiloxane (p-PDMS) highly stretchable conductive substrate. The p-PDMS surface is fabricated by a simple soft lithography process that replicates the 3D corrugated porous microstructures from a low-cost commercially available abrasive paper. Conductive polypyrrole (PPy) is polymerized on the p-PDMS surface by UV/Ozone (UVO) surface treatment to create the highly stretchable conductive PPy/p-PDMS film. The PPy/p-PDMS film shows a high stretchability maximum up to 80% strain. PPy/p-PDMS electrical properties based on the effects of critical PPy/p-PDMS process parameters such as UVO treatment time, deposition time, and abrasive paper grit size are evaluated in this paper. Results indicate that the highest electrical conductivity of 34.9 S m −1 is produced from the optimized PPy/p-PDMS process conditions. Reliability testing expressed through cyclical bending and stretching of PPy/p-PDMS films, up to 1000 cycles, is also reported as good PPy/p-PDMS repeatability with maximum 5% (bending) and 36% (20% strain stretching) resistance increases after 1000 repeating cycles. We create an elastic porous polydimethylsiloxane highly stretchable conductive substrate. The surface is fabricated by a simple soft lithography process that replicates the 3D corrugated porous microstructures from a low-cost commercially available abrasive paper. 出版日期： 2016-01-01 出處： RSC advances, 2016-01, Vol.6 (114), p.113344-113351 資源來源： Royal Society of Chemistry 識別號： ISSN: 2046-2069 識別號： EISSN: 2046-2069 識別號： DOI: 10.1039/c6ra24521h
