Roughening for Strengthening and Toughening in Monolayer Carbon Based Composites
نویسندگان
چکیده
Three-dimensional (3D) aggregation of graphene is dramatically weak and brittle due primarily to the prevailing interlayer van der Waals interaction. In this report, motivated by recent success in synthesis monolayer amorphous carbon (MAC) sheets, we demonstrate that outstanding strength large plastic-like strain can be achieved layered 3D MAC composites. Both surface roughening ultracompliant nature MACs count for high gradual failure MAC. Such properties are not seen when intact or multiple stacked used as building blocks This work demonstrates a counterintuitive mechanism initial defects low rigidity may help realize superb mechanical carbon.

Simultaneously Toughening and Strengthening Soy Protein Isolate-Based Composites via Carboxymethylated Chitosan and Halloysite Nanotube Hybridization
Chemical cross-linking modification can significantly enhance the tensile strength (TS) of soy protein isolate (SPI)-based composites, but usually at the cost of a reduction in the elongation at break (EB). In this study, eco-friendly and high-potential hybrid SPI-based nanocomposites with improved TS were fabricated without compromising the reduction of EB. The hybrid of carboxymethylated chit...
