Currently, Si as an active material for LIBs has been attracting much attention due to its high theoretical specific capacity (3572 mAh g-1). However, a disadvantage when using a Si negative electrode for LIBs is the abrupt drop of its capabilities during the cycling process. Therefore, there have been a few studies of polymers such as poly(vinylidene fluoride) (PVdF), carboxymethyl cellulose (...

Styrene Butadiene Rubbers (SBRs) are among the most useful synthetic rubbers which can be produced by two different methods of polymerization: emulsion and solution. These two polymerization methods lead to different final properties. In general, SBRs produced by the solution method (S-SBRs) have narrower Molecular Weight Distribution (MWD), higher content of cis-1,4 structure and lower glass t...

AIM This study evaluated the mortality experience of workers from the styrene-butadiene industry. METHODS The authors added seven years of follow up to a previous investigation of mortality among 17 924 men employed in the North American synthetic rubber industry. Analyses used the standardised mortality ratios (SMRs) to compare styrene-butadiene rubber workers' cause specific mortality (1943...

OBJECTIVE To review the epidemiologic literature on styrene and cancer. METHODS We reviewed studies of workers exposed to styrene in manufacturing and polymerization, in the reinforced plastics industry, and in styrene-butadiene rubber production. We also reviewed studies of workers monitored for styrene exposure, studies of environmental exposure, community-based case-control studies of lymp...

Abstract The environmental impact of rubber waste can be reduced by extending the lifetime products. It achieved developing graphene/rubber nanocomposites with good abrasion resistance. In this paper, we investigated how mixing technologies influence mechanical properties rubber. We added various amounts (0, 1, 5 and 10 phr) graphite graphene to mixtures using a two-roll mill, an internal mixer...

In order to determine the chemical composition distribution (CCD) of styrene-butadiene copolymers, gradient polymer elution chromatography has been performed. The separation is mainly based on differences in solubility among the copolymer molecules with different chemical composition. The solubility of a copolymer is dependent on the following parameters: temperature, type of solvent/non-solven...

In this study, a chemical dissolution treatment was used to recover rubber and carbon black (CB) from truck tire scrap, with gas oil acting as the solvent 4-Hydroxy-TEMPO catalyst for reactions. Montmorillonite clay separate solution CB other non-dissolved additives. The recovered were characterized together original scrap sample by XRD, SEM, BET thermal analysis, well FTIR 1H NMR spectral anal...
