新方法利用食用真菌生成防渗膜

Core Insights - Researchers from the University of Maine and the University of Cincinnati have developed a new method for creating a waterproof barrier using edible fungi, which shows potential as an alternative to plastic coatings [1] Group 1: Research and Development - The new waterproof membrane is formed by combining fungi with wood fibers, creating a protective layer that effectively blocks water, oil, and grease [1] - The materials used for the membrane include fluffy wood fibers primarily composed of cellulose nanofibers, which naturally possess hydrophobic properties [1] - The process involves growing the edible turkey tail mushroom with fibers to create a protective coating on various surfaces, including denim, polyester felt, birch veneer, and paper [1] Group 2: Performance and Characteristics - The research indicates that the fungi must grow for at least three days to form an effective waterproof barrier, with the new membrane not significantly increasing the thickness of the materials but altering their color to yellow, orange, or brown mottled patterns [1] - Treated fabrics and papers exhibit water droplets that bead and roll off, while untreated materials absorb water quickly [2] - The fungal coating is also effective in blocking the penetration of various liquids, including n-heptane, toluene, and castor oil [2]
