Wet Mixing with Organic Solvent for Synthesized cis-1,4-Polyisoprene-Based Rubber Composites

Antithrombin activity of a polyelectrolyte synthesized from cis-1,4-polyisoprene.

Properties of Vulcanized Polyisoprene Rubber Composites Filled with Opalized White Tuff and Precipitated Silica

Opalized white tuff (OWT) with 40 μm average particle size and 39.3 m(2)/g specific surface area has been introduced into polyisoprene rubber (NR). Their reinforcing effects were evaluated by comparisons with those from precipitated silica (PSi). The cure characteristic, apparent activation energy of cross-link (E(ac)) and reversion (E(ar)), and mechanical properties of a variety of composites ...

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...

Improved curing conditions and mechanical/chemical properties of Nitrile Butadiene Rubber Composites Reinforced with Carbon Based Nanofillers

Multiwall carbon nanotubes (MWCNTs) and carbon nanofibers (CNFs) with contents ranging from 1 to 10 phr (part per hundred parts of rubber) were selected and then characterized to reinforce acrylonitrile butadiene rubber (NBR) based composites. Fabrication of nanocomposites were done by a novel procedure and structural analysis along with variety of mechanical and chemical tests, according to th...

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...
