Oil-separating textileTaiwan Textile Research Institute (TTRI)_
The initial design purpose of Dual Membranes was to address ocean oil spills. In the event of large-scale marine oil pollution, Dual Membranes become hydrophilic and oleophobic. They quickly collect slick oil into the inner layer of a double-layer bag, after which the seawater is returned to the ocean. The membrane's properties can also be used in the design of cleaning supplies, self-cleaning applications, and other related household products.
