Abstract: Disclosed is an adhesive composition comprising an acrylic resin and an oligomeric resin having a reactive group and methods for making and using the adhesive composition in roofing membranes. The adhesive composition is thermally cured to form an adhesive layer. The adhesive composition may be applied to a membrane, such as a single-ply membrane, and then thermally cured. The single-ply membrane may then be adhered, via the adhesive layer, to a substrate, such as a roofing substrate.

Abstract: A roofing membrane includes a thermoplastic polyolefin (TPO) layer and a polyvinyl chloride (PVC) layer. The TPO layer forms a bottom layer of the roofing membrane, and the PVC layer is positioned atop the TPO layer so that the PVC layer forms a top layer of the roofing membrane. The TPO layer and the PVC layer are configured to be chemically compatible so that the TPO layer and the PVC layer are chemically bonded and function as a single roofing membrane. Compatibilizing includes at least one of (i) adding a compatibilizing agent to at least one of the TPO material and the PVC material prior to extrusion and (ii) positioning at least one compatibilizing film, prior to bonding, between the TPO material and the PVC material.

Abstract: Described are rigid and semi-rigid polyvinyl chloride (PVC) films, layers, or sheets, and methods of forming the same. The PVC products includes polyvinyl chloride resin and at least one 2D filler incorporated at the micro- or nano-scale. The film can have a low water permeance, for example, lower than that of a traditional PVC film. The water permeance of the PVC film described in this invention is significantly lower than that of a PVC film specifically developed for pipe jacketing applications. Standard pipe jacketing applications use either PVC or metal jacketing in their systems. The invention described herein produces a finished PVC product with a low water permeance similar to that of the metal jacketing products specifically developed for pipe jacketing applications.

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 5 ???. 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.

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.
