Changes in Porosity, Electrical and Surface Properties after Laundering of Heat-treated AgNW/PDMS/PU Nanofiber-web

In this study, to investigate the effects of heat treatment and polydimethylsiloxane (PDMS) coating on durability laundering, changes in porosity, electrical resistance, surface property heat-treated silver nanowire (AgNW)/PDMS/polyurethane (PU) nanofiber-web before after laundering were examined. To prepare conductive specimens, PU nanofiber-web, 1 wt% AgNW dispersion ethanol, two types PDMS precursors used. A total four specimens prepared: Specimen (The AgNW/PU nanofiber-web), AH AP PDMS-coated AHP AgNW/PDMS/PU nanofiber-web). The specimen was rinsed dehydrated under conditions according ISO 6330. porosity a single washing cycle, mean pore diameter size distribution measured. Linear resistance microscopic view evaluated. As result, many micro-pores distributed because treatment. After still had micro-pores, thus, improved laundering. Also, only changed slightly even which strengthened bonding between nanofibers nanowires, thus nanowires sufficiently remained And, showed that formed network evenly covered with onto surface. This result affected aforementioned performance, fact, lowest regardless However, it impossible measure due coating. Therefore, as well conductivity increase, but blocked enabled higher initial resistance.
