Methods, compositions, reagents, and systems that allow for the preparation and utilization of sulfonamide salt polymer electrolytes are disclosed herein. Methods and reagents to prepare sulfonamide salt monomers are also disclosed herein. The sulfonamide salt polymer electrolytes can be used as components in energy storage devices, conductive materials, electrochemical cells, gels, adhesives, and drug delivery vehicles.

Disclosed herein are redox-active 6-oxoverdazyl polymers having structures (S1) and (S2) synthesized via ring-opening metathesis polymerization (ROMP) and their solution, bulk, and thin-film properties investigated. Detailed studies of the ROMP method employed confirmed that stable radical polymers with controlled molecular weights and narrow molecular weight distributions (<1.2) were produced. Thermal gravimetric analysis of a representative example of the title polymers demonstrated stability up to 190 C., while differential scanning calorimetry studies revealed a glass transition temperature of 152 C. An ultrathin memristor device was produced using these polymers, namely a 10 nm homogeneous thin film of poly-[1,5-diisopropyl-3-(cis-5-norbornene-exo-2,3-dicarboxiimide)-6-oxoverdazyl] (P6OV), a poly-radical with three tunable charge states per each radical monomer: positive, neutral and negative.

There is provided a method of producing a bioactive polymer filament, the method comprising: providing a base polymer powder and a bioactive copolymer; mixing the base polymer powder with the bioactive copolymer to obtain a mixture; and extruding a bioactive polymer filament from the mixture at an extrusion temperature profile that is based on a predetermined melt/softening temperature and a predetermined onset degradation temperature of the bioactive polymer; and performing a post-extrusion thermal analysis on the extended bioactive polymer filament to assess onset degradation of the bioactive copolymer in the filament. There is also provided a bioactive polymer filament obtained from said method and a fused filament fabrication (FFF) or fused deposition modelling (FDM) based three-dimensional printing method.

A manufactured wood based siding or cladding product made from an engineered wood composite including, but not limited to, oriented strand board (OSB), hardboard, plywood, and combinations thereof, with fire-resistant properties (e.g., resistance to flame spread, ignition and combustion) imparted during the manufacturing process. An engineered wood-based composite siding product (in various forms, including lap, panel or trim) possessing such material properties is better suited for meeting the requirements of certain communities or areas where building codes require such protection due to the risk of fires (such as those posed within the boundaries of the wildland-urban interface, WUI). Engineered or manufactured wood-based composite products are typically manufactured by assembling multiple layers, then consolidating these layers using heat and pressure. A fines layer comprising wood or lignocellulosic wood particles is currently applied to the face of engineered wood-based composite siding products (e.g., lap siding, panel siding, trim) to provide an appropriate outer appearance, or other features, to the product. In various exemplary embodiments, the present invention treats the particles that make up the fines layer before incorporation of the particles into the manufacturing process (i.e., in-process). The treatment comprises adding ingredients or additives (using appropriate methods) that impart desired protection when exposed to a fire event. Ingredients, for example, include various borate-based chemistries, minerals, or combinations thereof that impart the desired protection.

The present disclosure relates to cross-linked polyelectrolytes comprising polyelectrolyte, and composite materials comprising said cross-linked polyelectrolytes. The present disclosure further relates to membrane electrode assemblies comprising the cross-linked polyelectrolytes and composites of the disclosure, and electrochemical devices comprising the disclosed membrane electrode assemblies.
