“…This report also builds on previous works within our group of an electrochemical in situ polymerization technique that used acrylic acid to generated fiber color and reversible malleability, alongside increased adhesion in epoxy. − For these surface modification procedures, all studies have included only one monomer at a time, leading to one type of surface chemistry installed. Therefore, another focus of this work was to examine the possibility of copolymerization, as this would generate a myriad of potential properties to be used in tailoring the fiber–matrix interface (Figure ).…”

Carbon fibers were surface modified using mixed grafting solutions of methyl methacrylate and glycidyl (epoxy) methacrylate in ratios of 0:100; 25:75; 50:50; 75:25; and 100:0, respectively. When evaluated in an epoxy resin, all modified fibers showed significant improvement in fiber-to-matrix adhesion. Notably, the surface-grafted polymer with blends of methyl methacrylate:glycidyl methacrylate of 0:100 and 25:75, respectively, showed a >200% improvement in adhesion relative to control fibers. When evaluated in PMMA, again significant adhesion improvements were observed, though fibers grafted with ≥25% methyl methacrylate were statistically indistinguishable. This shows that by correctly tuning the surface chemistry an optimal covalent sizing can be developed for thermoplastic and thermoset resins. As an additional benefit, a significant improvement in the treated fiber’s tensile strength and modulus was also observed.

“…Although many studies are concerned with plasma for polymer surface modifications, many of them involve radio-frequency (RF) plasma [66,67], with only a few using direct current (DC) plasma [68]. A DC plasma is more stable in comparison with RF/MW/inductively coupled plasmas, with it being easy to control and to diagnose a DC plasma by comparing it with RF/MW/inductively coupled plasma.…”

Changes of a material biointerface allow for specialized cell signaling and diverse biological responses. Biomaterials incorporating immobilized bioactive ligands have been widely introduced and used for tissue engineering and regenerative medicine applications in order to develop biomaterials with improved functionality. Furthermore, a variety of physical and chemical techniques have been utilized to improve biomaterial functionality, particularly at the material interface. At the interface level, the interactions between materials and cells are described. The importance of surface features in cell function is then examined, with new strategies for surface modification being highlighted in detail.

Modified graphene oxide (GO)/carbon fiber (CF)/epoxy (EP) composites are prepared by combining grafting and sizing methods. The effects of different molecular chain lengths of poly(oxypropylene)amines on the surface grafting of GO, as well as the interfacial structure and properties of CF and EP resin after sizing, were investigated. The "palm-tree"-like structure interfacial enhancement theory was innovatively proposed. The characterization results showed that the short-chain poly(oxypropylene)amines modified GO (D400-GO) had a good effect on the interfacial properties of CF and EP resin. When the content of D400-GO was 0.20 wt%, the interfacial shear strength was as high as 70.56 MPa, which was 37% higher than the virgin CF. In this article, a new theoretical model is proposed for multiscale interfacial enhancement.
