Graphene has received extensive research interest from both scientific and technological communities due to its excellent physical properties. However, owing two-dimensional structure, graphene experiences brittle fracture under external loading, which limits application as reinforcing fillers in composites. In this study, we apply an origami technique improve the flexibility of nanoindentation. Based on intensive molecular dynamics simulation, found that (GOri) can withstand loads...
Graphene and its derivatives have been widely used as reinforcing nanofillers for high-performance polymer nanocomposites. The effectiveness of the reinforcement largely depends on properties nanofiller-matrix interface, which can be represented by interfacial shear strength (IFSS). This work systematically investigates IFSS enhancements polyethylene (PE) nanocomposites reinforced graphene origami (GOri) through molecular dynamics pull-out simulations. When two-dimensional (2D) is...
Brittleness remains the key bottleneck for graphene to be used as impact protection materials and this obstacle can overcome by origami-modified graphene. Herein we employed molecular dynamics simulation investigate perforation behaviours of origami (Gori) under ballistic from a diamond projectile. We found that threshold penetration velocity GOri improved 46.27% compared with its pristine counterpart. Under small loading at low speed, experiences unique unfolding process hence has...
