Detailed atomistic (united atoms) molecular dynamics simulations of several graphene based polymer (polyethylene, PE) nanocomposite systems have been performed. Systems with graphene sheets of different sizes have been simulated at the same graphene concentration (~3%). In addition, a periodic graphene layer (" infinite sheet ") has been studied.

In the present study, silane-functionalized graphene (f-graphene)-reinforced chitosan nanocomposite films exhibiting enhanced mechanical properties have been prepared by the solution casting method. These nanocomposite films were characterized by X-ray diffraction, Raman spectroscopy and thermogravimetric analysis. In order to investigate the effect of(More)
A green approach for the preparation of water-dispersible functionalized graphene via one-step electrochemical exfoliation of graphite using 7,7,8,8-tetracyanoquinodimethane (TCNQ) anions as surface modifiers and electrolytes was described. TCNQ is an organic charge-transfer complex with electron accepting and noteworthy electrical properties. The(More)
Technology of displaying static images in portable displays, advertising panels and price tags pursues significant reduction in power consumption and in product cost. Driving at a low-frequency electric field in fringe-field switching (FFS) mode can be one of the efficient ways to save powers of the recent portable devices, but a serious drop of(More)
