Abstract: A method of forming a porous structure involves mixing a solvent with a curable material which disperses in the solvent such that the mixture has greater than 50% solvent content. The mixture is deposited on a substrate and viscosity of the mixture is increased. The curable material in the mixture is cured while a shape of the curable material is maintained by the solvent. After curing, the solvent is removed from the structure.

Abstract: A method of producing functionalized graphene oxide includes mixing graphene oxide with a reactive monomer containing at least one epoxy functional group and a secondary functional group that is selected from vinyl, acrylate, methacrylate, and epoxy to form a mixture, adding an activation agent, heating and stirring the mixture, cooling the mixture, separating the particles from the mixture, and drying the particles to produce functionalized graphene oxide. A method of manufacturing a cured polymer resin using functionalized graphene oxide includes mixing functionalized graphene oxide with a resin precursor to produce a functionalized graphene mixture, wherein the particles contain functional groups nearly identical to, or identical to, a polymer precursor material, adding a curing initiator to the functionalized graphene mixture and mixing to produce a formulation, depositing the formulation into a desired shape, and curing the formulation to form a polymer having functionalized graphene oxide groups in a base polymer material.

Abstract: A porous polymer aerogel, wherein the aerogel has greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone. A method of fabrication of a porous polymer aerogel amine material, includes preparing a solution comprising at least a solvent, amine monomers having protected amino groups, one or more crosslinkers, one or more radical initiators, and a nitroxide mediator, removing oxygen from the solution, heating the solution to promote polymerization and to produce a polymerized material, performing solvent exchange with the polymerized material, causing a deprotection reaction in the polymerized material to remove groups protecting the amino groups, soaking and rinsing the material to remove excess reagents and any byproducts of the deprotection reaction, and drying the material to produce the amine sorbent. A system to separate CO2 from other gases, comprising a polymer porous aerogel sorbent having greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone.

Abstract: Disclosed herein are methods of producing metal nanoparticle-decorated carbon nanotubes. The methods include forming a reaction mixture by combining a first solution with a second solution, wherein the first solution comprises polymer-coated metal nanoparticles comprising metallic nanoparticles coated with a polymer, and wherein the second solution comprises carbon nanotubes. The methods also include heating the reaction mixture to a temperature greater than a glass transition temperature of the polymer for a time sufficient to cause the polymer-coated metal nanoparticles to bind to the carbon nanotubes forming the metal nanoparticle-decorated carbon nanotubes.
