Abstract: Boron nitride nanotube (BNNT) - polyimide (PI) and poly-xylene (PX) nano-composites, in the form of thin films, powder, and mats may be useful as layers in electronic circuits, windows, membranes, and coatings. The processes described chemical vapor deposition (CVD) processes for coating the BNNTs with polymeric material, specifically PI and PX. The processes rely on surface adsorption of polymeric material onto BNNTs as to modify their surface properties or create a uniform dispersion of polymer around nanotubes. The resulting functionalized BNNTs have numerous valuable applications.

Abstract: 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.

Abstract: As disclosed herein, the viscoelastic performance of boron nitride nanotube (BNNT) materials may be enhanced and made into useful formats by utilizing purified BNNTs, aligned BNNTs, isotopically enhanced BNNTs, and density controlled BNNT material. Minimizing the amounts of boron particles, a-BN particles, and h-BN nanocages, and optimizing the h-BN nanosheets has the effect of maximizing the amount of BNNT surface area present that may interact with BNNTs themselves and thereby create the nanotube-to-nanotube friction that generates the viscoelastic behavior over temperatures from near absolute zero to near 1900 K. Aligning the BNNT molecular strands with each other within the BNNT material also generates enhanced friction surfaces. The transport of phonons along the BNNT molecules may be further enhanced by utilizing isotopically enhanced BNNTs.
