Journal ArticleDOI
Enhanced mechanical properties of nanocomposites at low graphene content.
TL;DR: Graphene platelets significantly out-perform carbon nanotube additives in terms of mechanical properties enhancement, and may be related to their high specific surface area, enhanced nanofiller-matrix adhesion/interlocking arising from their wrinkled (rough) surface, as well as the two-dimensional geometry of graphene platelets.
Journal ArticleDOI
Hydrophobic, Flexible, and Lightweight MXene Foams for High-Performance Electromagnetic-Interference Shielding
TL;DR: For the first time, an efficient and facile approach is reported to fabricate freestanding, flexible, and hydrophobic MXene foam with reasonable strength by assembling MXene sheets into films followed by a hydrazine-induced foaming process.
Journal ArticleDOI
Tough Graphene−Polymer Microcellular Foams for Electromagnetic Interference Shielding
TL;DR: This work provides a promising methodology to fabricate tough and lightweight graphene-PMMA nanocomposite micro cellular foams with superior electrical and EMI shielding properties by simultaneously combining the functionality and reinforcement of the graphene sheets and the toughening effect of the microcellular cells.
Journal ArticleDOI
Fracture and fatigue in graphene nanocomposites
Mohammed A. Rafiee,J. Rafiee,Iti Srivastava,Zhou Wang,Huaihe Song,Zhong-Zhen Yu,Nikhil Koratkar +6 more
TL;DR: The fracture toughness, fracture energy, and fatigue properties of an epoxy polymer reinforced with various weight fractions of functionalized graphene sheets, and under fatigue conditions, are reported.
Journal ArticleDOI
Electrically conductive polyethylene terephthalate/graphene nanocomposites prepared by melt compounding
Hao-Bin Zhang,Wenge Zheng,Qing Yan,Yong Yang,Ji-Wen Wang,Zhao-Hui Lu,Guo-Ying Ji,Zhong-Zhen Yu +7 more
TL;DR: Graphene nanosheets were prepared by complete oxidation of pristine graphite followed by thermal exfoliation and reduction in this paper, and the incorporation of graphene greatly improved the electrical conductivity of PET, resulting in a sharp transition from electrical insulator to semiconductor with a low percolation threshold of 0.47 vol.%.
