摘要:
Thermoresponsive composite switch (TRCS) membranes for ion batteries include a porous scaffolding providing ion channels and a thermoresponsive polymer coating. Boron nitride nanotube (BNNT)/polymer composite TRCS membrane embodiments are preferable due to unique BNNT properties. A BNNT scaffold coated with one or more polymers may form a composite separator with tunable porosity (porosity level and pore size distribution), composition, wettability, and superior electronic isolation, oxidative/reduction resistance, and mechanical strength. The BNNT/polymer composite TRCS membrane optimizes the performance of ion batteries with tunable separator thicknesses that may be under 5μιη. Nano- scale porosity with thin separator thicknesses improves the charge density of the battery. Nano- scale architecture allows for reversible localized switching on the nano scale, in proximity to thermally stressed ion substrates. Polymer thermal expansion will decrease porosity at temperatures approaching the thermal runaway point. The BNNT polymers composite therefore functions as a TRCS.

This invention provides an optical member having a high antireflection effect also on a base material with a low refractive index. This invention relate to an optical member in which a laminated body is formed on a base material surface, in which the laminated body has a porous layer or a layer having an uneven structure on the surface and having a polymer layer has a thickness of 10 nm or more and 150 nm or less and containing a maleimide copolymer between the porous layer or the layer having an uneven structure and the base material.
