Dynamic mechanical, mechanical and thermal analysis of CPI/NBR blends: effect of blend composition and crosslink density

Composites made from a combination of cis-polyisoprene (CPI) and nitrile butadiene rubber (NBR) were investigated to determine the effect of varying proportions of each additive on the mechanical and thermal properties of the final product. The use of a scanning electron microscope to quantify the structure of the material revealed that all samples were homogenous. Young's modulus and tensile strength were two of the mechanical properties studied. The blend composition ...

Effective thermal conductivity and diffusivity of GeSeSb glasses measured simultaneously as a function of temperature and fit to empirical equations

The effective thermal conductivity and thermal diffusivity was measured for chalcogenide glass samples of the formulation Ge30-xSe70Sbx (x = 10, 15, 20, 25). It was found that both the effective thermal conductivity and thermal diffusivity were independent of temperature up to 160º C. After this point, both properties were found to increase with increasing temperature until they reached a maximum value at a point near the glass transition temperature of the glass. After reaching ...

Measurement of Thermal Transport Properties in Metal Doped Polypyrrole

Metal doping of a polypyrrole matrix was carried out. Nickel and Cobalt were the two metals that were used in this study, and three samples were prepared, one containing 100% Co, one containing 50% Co and 50% Ni, and finally, one containing 100% Ni. The effective thermal conductivity and thermal diffusivity were evaluated, and it was determined that metal doping of the polymer matrix resulted in increases in both the thermal conductivity, and the ...

Evaluation of Morphological Effect on Thermal and  Mechanical Performance of PS/PMMA/CdS  Nanocomposite Systems

The thermal and mechanical properties of PS/PMMA immiscible polymer blends were investigated. The effects of the dispersion of CdS nanoparticles on these properties were also investigated. The dispersion of the nanoparticles was found to result in an increase in glass transition temperature, as well as the thermal conductivity. The PS matrix was found to become more brittle and the PMMA matrix was found to become more compact upon the ...

Mechanical and thermal characterization of cis-polyisoprene and trans-polyisoprene blends

The mechanical and thermal properties of blends of cis-polyisoprene (CPI) and trans-polyisoprene (TPI) are investigated and compared to those of the pure elastomers. It was found that the elastic modulus and tensile strength increased with increasing TPI content and that the thermal conductivity, thermal diffusivity, and specific heat of the blends also increased with increasing TPI content. In contrast to this trend, the measured thermal properties of pure TPI were ...
