Structure and mechanical properties of graphene oxide-reinforced polycarbonate

Molecularly Engineered Unparalleled Strength and Supertoughness of Poly(urea‐urethane) with Shape Memory and Clusterization‐Triggered Emission

“…The mechanical properties of DPUU‐2000 exceeded most of the values previously reported for PUUs (Figure 2C), [ 25–34 ] moreover, the above tensile strength was even comparable to engineering plastics (Figure 2D). [ 35–40 ] In contrast, LPUU‐X samples showed lower tensile strength (36.6 ± 0.5, 29.3 ± 1.9, and 17.3 ± 0.5 MPa for LPUU‐1000, LPUU‐2000, and LPUU‐3000, respectively) than the corresponding DPUU‐X and TPUU‐X samples, which featured rigid structures and restricted molecular chain motion attributable to the ππ interactions between benzene rings and adjacent conjugated CN bonds. Surprisingly, they also had high elongations at the break, with a particularly high value observed for TPUU‐3000 (1043.6 ± 64.9%).…”

PECVD application to obtain polymer coated graphene nanoplatelets and development of new epoxy nanocomposites

“…The superior properties of GNPs have enabled their use in recent years as high-efficiency fillers to produce polymer composites and coatings with improved properties [1]. Nanocomposites containing small amounts of GNPs exhibit superior properties such as mechanical, thermal, gas barrier, electrical conductivity, and anticorrosion, to that of pure polymers [6][7][8]. The enhancement of the composite properties strongly depends on the level of dispersion of the GNPs in the polymer matrix.…”

Polymer/Graphene Nanocomposite Membranes: Status and Emerging Prospects

“…In this regard, polymeric nanocomposite nanofibers have been tested [69]. Graphene-reinforced polymeric nanofibers have been used to design nanocomposite membranes [70][71][72][73].…”
