ABSTRACTFaster and more effective surface modification processes of polymer materials by UV/ozone treatment were investigated. The employment of ex-situ generated ozone and/or temperature control contributed to the faster and more effective modification. The UV/ozone treatment showed long-term stable hydrophilic surfaces for 6 months, in contrast to oxygen plasma treatment, which showed hydrophobic recovery. XPS analysis revealed that UV/ozone treatment with ex-situ generated ozone and temperature control added ester (-COOR) on COP sample compared to UV/ozone treatment without the additional ozone and temperature control.

In this study, a portable and disposable paper-based microbial fuel cell (MFC) was fabricated. The MFC was powered by Rhodopseudomonas palustris bacteria (R. palustris). An activated carbon sheet-based anode pre-loaded organic matter (starch) and R. palustris was used. By using starch in the anode, R. palustris-loaded on the anode could be preserved for a long time in dry conditions. The MFC could generate electricity on-demand activated by adding water to the anode. The activated carbon sheet anode was treated by UV-ozone treatment to remove impurities and to improve its hydrophilicity before being loaded with R. palustris. The developed MFC could generate the maximum power density of 0.9 μW/cm2 and could be preserved for long-term usage with little performance degradation (10% after four weeks).
