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: A method of manufacturing a cured polymer resin using functionalized graphene oxide, includes mixing functionalized graphene oxide with a resin precursor and an optional solvent to produce a functionalized graphene solution wherein the particles contain functional groups nearly identical to, or identical to, a polymer precursor material, adding a curing initiator to the resin solution and mixing to produce a resin solution, 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. A method of producing functionalized graphene oxide includes dispersing graphene oxide into a solvent to produce dispersed graphene oxide, mixing the dispersed graphene oxide with a reactive molecule containing at least one epoxy functional group and a secondary functional group that is selected from vinyl, acrylate, methacrylate and epoxy to form a solution, adding an activation agent, heating and stirring the solution, cooling the solution, separating the particles from solution, and drying the particles to produce functionalized graphene oxide. A composition of matter includes exfoliated, functionalized graphene oxide particles, a curing initiator, a polymer precursor material, wherein the particles contain functional groups nearly identical to, or identical to, a polymer precursor material.

Abstract: A method of forming lightweight structures from particle networks includes functionalizing edges of particles of an anisotropic material, exfoliating of the particles to form sheets of the material, aligning the sheets of material to form a network of multi-layered and aligned particles, and forming a structure out of the network of particles. One example uses graphite powder mixed into 4-aminobenzoic acid for edge functionalization, and exfoliation occurs with sonication in a solvent. The resulting particles undergo alignment with an aligning nozzle that also dispenses the aligned particles to form a structure.
