Nanomechanics of graphene oxide-bacteriophage based self-assembled porous composites

Self-assembled electrical biodetector based on reduced graphene oxide.

Large-scale fabrication of graphene-based devices is an aspect of great importance for various applications including chemical and biological sensing. Toward this goal, we present here a novel chemical route for the site-specific realization of devices based on reduced graphene oxide (RGO). Electrodes patterned by photolithography are modified with amino functional groups through electrodeposit...

High Performance Graphene Oxide Based Rubber Composites

In this paper, graphene oxide/styrene-butadiene rubber (GO/SBR) composites with complete exfoliation of GO sheets were prepared by aqueous-phase mixing of GO colloid with SBR latex and a small loading of butadiene-styrene-vinyl-pyridine rubber (VPR) latex, followed by their co-coagulation. During co-coagulation, VPR not only plays a key role in the prevention of aggregation of GO sheets but als...

Controlling the photoconductivity: Graphene oxide and polyaniline self assembled intercalation

Self-assembled reduced graphene oxide/polyacrylamide conductive composite films.

Substrate supported conductive thin films are prepared by the self-assembly of graphene oxide (GO) on a cationic polyacrylamide (CPAM) layer followed by a subsequent chemical reduction. During self-assembly, the dispersed GO nanosheets with a negative zeta potential from solution are spontaneously assembled onto the positively charged CPAM adsorption layer. In addition, CPAM adsorption on the s...

Carbon Nanotube-Based Composites Synthesized Using Porous Aluminum Oxide

Devices on the basis of carbon nanotube (CNT) were not used extensively up to date [6]. That is connected with a problem of receiving the reliable, corresponding to the sizes and properties of CNT, electrode systems [7]. As a rule, usually represented CNT-devices contain other elements of the scheme, including electrodes, of the micron size. In devices on the base of CNT-array, electrodes can h...
