Abstract: Technologies are generally described to increase interlayer adhesion of a 3D printed article. A printhead of a 3D printing system may include an extrusion nozzle configured to deposit one or more polymer layers onto a substrate to form the 3D printed article. A microplasma source may be coupled to the extrusion nozzle and may be configured to treat a surface of the substrate or a surface of the deposited polymer layers with plasma from the microplasma. The plasma may include at least one reactive species that may oxidize the surface of the substrate or the surface of the deposited polymer layer upon treatment in order to increase the interlayer adhesion of the 3D printed article.

Abstract: Technologies are generally described for a membrane that may incorporate a graphene layer perforated by a plurality of nanoscale pores. The membrane may also include a gas sorbent that may be configured to contact a surface of the graphene layer. The gas sorbent may be configured to direct at least one gas adsorbed at the gas sorbent into the nanoscale pores. The nanoscale pores may have a diameter that selectively facilitates passage of a first gas compared to a second gas to separate the first gas from a fluid mixture of the two gases. The gas sorbent may increase the surface concentration of the first gas at the graphene layer. Such membranes may exhibit improved properties compared to conventional graphene and polymeric membranes for gas separations, e.g., greater selectivity, greater gas permeation rates, or the like.
