Abstract: Copoly(imide oxetane) materials are disclosed that can exhibit a low surface energy while possessing the mechanical, thermal, chemical and optical properties associated with polyimides. The copoly(imide oxetane)s are prepared using a minor amount of fluorinated oxetane-derived oligomer with sufficient fluorine-containing segments of the copoly(imide oxetane)s migrate to the exterior surface of the polymeric material to yield low surface energies. Thus the coatings and articles of manufacture made with the copoly(imide oxetane)s of this invention are characterized as having an anisotropic fluorine composition. The low surface energies can be achieved with very low content of fluorinated oxetane-derived oligomer. The copolymers of this invention can enhance the viability of polyimides for many applications and may be acceptable where homopolyimide materials have been unacceptable.

Abstract: Systems, methods, and devices of the various embodiments provide for the creation of holey graphene meshes (HGMs) and composite articles including HGMs. Various embodiments provide solvent-free methods for creating arrays of holes on holey graphene-based articles formed from dry compression (such as films, discs, pellets), thereby resulting in a HGM. In further embodiments, a HGM can used as part of a composite, such as by: 1) embedding a HGM into another matrix material such as carbon, polymer, metals, metal oxides, etc; and/or (2) the HGM serving as a matrix by filling the holes of the HGM or functionalizing the HGM body with another one or more materials. In various embodiments, HGM can also be made as a composite itself by creating holes on dry-compressed articles pre-embedded with one or more other materials.

Abstract: Described herein are composites produced with a barrier ply. The barrier-ply prevents excessive mixing between conventional composite precursors and stoichiometrically-offset precursors during a cure process by gelling early in the cure cycle before extensive mixing can occur. Excess mixing requires the use of thicker offset resin layers with a large stoichiometric offset, which may limit the performance of unitized structures. The use of the barrier plies described herein address this issue and improves the mechanical properties of the final composite product as well as the efficiency for making the composites.

Abstract: Copoly(imide oxetane) materials are disclosed that can exhibit a low surface energy while possessing the mechanical, thermal, chemical and optical properties associated with polyimides. The copoly(imide oxetane)s are prepared using a minor amount of fluorinated oxetane-derived oligomer with sufficient fluorine-containing segments of the copoly(imide oxetane)s migrate to the exterior surface of the polymeric material to yield low surface energies. Thus the coatings and articles of manufacture made with the copoly(imide oxetane)s of this invention are characterized as having an anisotropic fluorine composition. The low surface energies can be achieved with very low content of fluorinated oxetane-derived oligomer. The copolymers of this invention can enhance the viability of polyimides for many applications and may be acceptable where homopolyimide materials have been unacceptable.
