| 1 | Achieving higher performances without an external curing agent in natural magnolol-based epoxy resin显示文摘Bio-based epoxy thermoset prepared from renewable biomass raw materials can alleviate fossil energy crisis and reduce environmental pollution,which satisfies the needs of sustainable social development.In this study,a bio-based epoxy thermoset precursor(MGOL-EP) was synthesized from a naturally occurring magnolol through a facile and efficient one-step process.And the fully bio-based epoxy thermoset(MGOL-EP-SC) was obtained by self-curing without adding any other hardener.MGOL-EP-SC revealed an extremely high glass-transition temperature(T_(g)) of 265℃ and char yield of 53.2%(in N;),which were at the highest level among the fully bio-based epoxy thermosets reported so far.In addition,when the MGOL-EP was cured with 4,4’-methylenedianiline(DDM),T_(g)of the MGOL-EP/DDM was decreased by 61℃ and the other comprehensive performance had also been decreased,which was due to a reduction in biphenyl structure content and cross-linking density by adding the external curing agents.Moreover,the MGOL-EP-SC presented certain killing rate(48.4%) to Staphylococcus aureus.These findings provide a new design strategy for engineering high-performance and functional epoxy thermoset with high biomass content. | Qi Cao Zhihuan Weng Yu Qi Jiahui Li Wentao Liu Chengde Liu Shouhai Zhang Zhiyong Wei Yousi Chen Xigao Jian | 2022 | Chinese Chemical Letters2022，33，4： | 2 |

| 5 | The Gas Sensitivity of Polypyrrole Film Fabricated by in Situ Polymerization显示文摘1 Results Polypyrrole (PPy) is a typical conducting polymer with high conductivity and good stability,and has been widely used for detection of gases including ammonia and nitroxide[1].However the reversiblity and selectivity of the response to these gases are always not satisfying.In the paper,conductive PPy film was deposited on the interdigital electrode modified by one bilayer of poly(diallyldimethylammonium chloride) and poly(sodium styrenesulfonate),by in-situ polymerization with FeCl3 as oxidizin... | Chen Yousi, Li Yang, Yang Mujie(Department of polymer science and engineering, Zhejiang University, Hangzhou 310027, China) | 2007 | 复旦学报(自然科学版)2007，46，5： | 0 |
