摘要:
Embodiments of the present disclosure pertain to methods of forming a polymer composite by exposing a solution that includes nanomaterials (e.g., functionalized graphene nanoribbons) and cross-linkable polymer components (e.g., thermoset polymers and monomers) to a microwave source, where the exposing results in the curing of the cross-linkable polymer component in the presence of the nanomaterial to form the polymer composite. The solution may be exposed to a microwave source in a geological formation such that the formed polymer composite becomes embedded with the geological formation and thereby enhances the stability of the geological formation. Additional embodiments of the present disclosure pertain to the aforementioned polymer composites.
摘要:
The invention provides cryogels whose porosity, pore size, pore connectivity, swelling agent concentration, and/or specific volume undergoes a change from a first value to a second value in response to an electrical stimulus. The cryogels have interconnected macropores which greatly enhance their ability to rapidly undergo volumetric collapse when subjected to moderate electric fields. The cryogels of the invention can be easily integrated into arrays capable of rapid configurational and chromatic optical modulations, and when loaded with drugs, are able to coordinate the delivery profile of multiple drugs. The cryogel can be prepared by polymerizing an aqueous solution of charged monomers and cross-linker monomers at a temperature below the freezing temperature of the solvent.

摘要:
A method for making a thermoplastic material includes: (a) partially crosslinking an elastomer composition at a first crosslinking temperature to form a thermoplastic, partially crosslinked elastomer composition; (b) mixing a thermoplastic polymer composition with the thermoplastic, partially crosslinked elastomer composition and heating the mixture to a second crosslinking temperature higher than the first crosslinking temperature, wherein the thermoplastic polymer composition is liquid at the second crosslinking temperature; and (c) continuously mixing the mixture while further crosslinking the elastomer composition to form a thermoplastic material having a dispersed phase of crosslinked elastomer composition in the thermoplastic polymer composition. The elastomer composition may include an elastomer compounded with a curing agent and optionally additional components. A thermoplastic material resulting from this process may be molded or shaped by any method used for forming thermoplastic materials into articles, such as molding, extrusion, or thermoforming.
