Effect of surfactant and electron treatment on the electrical and thermal conductivity as well as thermal and mechanical properties of ethylene vinyl acetate/expanded graphite composites

14-May-2015 | Jeremia Shale Sefadi, Adriaan Stephanus Luyt, Jürgen Pionteck, Francesco Piana, Uwe Gohs, Journal of Applied Polymer Science, 2015

ABSTRACT This study presents an investigation of the electrical and thermal conductivities of composites based on an ethylene vinyl acetate (EVA) copolymer matrix and nanostructured expanded graphite (EG). To improve the EG dispersion in EVA, EG sheets were modified by treating them with the ...

LDPE/EVA/graphene nanocomposites with enhanced mechanical and gas permeability properties

04-May-2015 | Meysam Tayebi, Ahmad Ramazani S.A, M. T. Hamed Mosavian, Ahmad Tayyebi, Polymers for Advanced Technologies, 2015

In the present work, graphene oxide (GO) and reduced graphene oxide (RGO) were incorporated at low‐density polyethylene (LDPE)/ethylene vinyl acetate (EVA) copolymer blend using solution casting method. Monolayer GO with 1‐nm thickness and good transparency was synthesized using the well‐known ...

Polystyrene‐montmorillonite core–shell particles via Pickering emulsion polymerization and their use as reinforcing additives for polypropylene and ethylene vinyl acetate

02-May-2015 | A.B. Moustafa, M.E. Abd El‐Aziz, A.M. Rabea, H.A. Essawy, Polymer Engineering and Science, 2015

Solid particles can be used as stabilizers for oil/water (o/w) emulsions instead of the conventional surfactants. Emulsion polymerization of styrene, as an example of polymerizable oil, was started in the current study after ultrasonication of the monomer into aqueous phase with aid of ...

Green composites and blends from leather industry waste

25-Apr-2015 | Luciana Sartore, Fabio Bignotti, Stefano Pandini, Alberto D'Amore, Luca Di Landro, Polymer Composites, 2015

Blends based on protein hydrolysate (PH), derived from waste products of the leather industry, and poly(ethylene‐co‐vinyl acetate) (EVA), were obtained by reactive blending and their physico‐chemical properties as well as their mechanical and rheological behavior were evaluated. The effect of ...

Formulation and characterization of oleogels based on high‐oleic sunflower oil and ethylene vinyl acetate copolymer/polypropylene blends

18-Apr-2015 | J.E. Martín‐Alfonso, J. M. Franco, Polymer Engineering and Science, 2015

New oleogel formulations based on high‐oleic sunflower oil (HOSO) and ethylene vinyl acetate copolymer (EVA)/polypropylene (PP) blends were prepared using the mixing rheometry technique and further characterized. The effects of PP tacticity and EVA vinyl acetate (VAc) content on the rheological, ...

The effect of expanded graphite on the physical properties of conductive EVA/wax phase change blends for thermal energy storage

18-Apr-2015 | Mokgaotsa J. Mochane, Adriaan S. Luyt, Polymer Composites, 2015

A study of the morphology, dynamic mechanical, impact, and tensile properties of ethylene vinyl acetate copolymer (EVA)/expanded graphite (EG) and EVA/wax/EG composites is presented. The composites were prepared by melt blending. The EVA/EG composites showed ductile behavior, while brittle ...

ChemInform Abstract: Selective Oxygenation of Alkynes: A Direct Approach to Diketones and Vinyl Acetate.

09-Apr-2015 | Xiao‐Feng Xia, Zhen Gu, Wentao Liu, Ningning Wang, Haijun Wang, Yongmei Xia, Haiyan Gao, Xiang Liu, ChemInform, 2015

Abstract Arylalkynes can be selectively converted into α‐diketones under copper catalysis, and also into vinyl acetates under metal‐free conditions, using PhI(O‐Ac)2 as oxidant.

Evaluation of the efficiency of copolymers of methyl methacrylate and vinyl acetate synthesized by emulsion polymerization for control of aqueous filtrate loss

28-Mar-2015 | Rita de Cassia P. Nunes, Renata V. Pires, Elizabete F. Lucas, Journal of Applied Polymer Science, 2015

ABSTRACT One of the main problems faced while drilling oil wells is loss of fluid to the rock formation. This loss can be reduced with the use of chemical additives called filtrate controllers, which must be tailored to the specific characteristics of the rock formation and drilling ...

Ethylene vinyl acetate blends with cellulosic fillers and reinforcements

28-Mar-2015 | Luciana Sartore, Alberto D'Amore, Luca Di Landro, Polymer Composites, 2015

Polymeric blends based on ethylene vinyl acetate (EVA) rubbers filled with high molecular weight carboxymethyl cellulose were investigated in view of possible employment as biodegradable materials. The effect of vinyl acetate (VA) content and of addition of transesterification agent to increase ...
