Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
Inorganic polymers (geopolymers) with varying chemical compositions were subjected to a number of tests in an effort to demonstrate that varying their chemical composition, as well as curing conditions can allow researchers to create geopolymers that fit specific applications based on their microstructure, thermal conductivity, mechanical strength and reliability, and thermal shrinkage behavior....
Poly(methyl methacrylate)-silica nanocomposite (PSN) foams were formulated for the comparison of the effect of vinyl-modified silica (VMS) and raw silica (RS) particles on cell structure, insulation properties, and insulation properties. It was found that those thermoplastic foams containing VMS particles had improved dispersion capability than those containing RS particles. The incorporation of VMS particles was found to reduce the cell size and increase the cell density of the ...
Four electrically conductive polymers were tested for their thermal transport properties to better understand their degradation mechanism with temperature. The samples that were tested were polyaniline polymers doped with varying amounts of nickel and aluminum. It was found that the thermal conductivities increased as the aluminum:nickel ratio increased, and that the thermal conductivity and thermal diffusivity of the samples increased with temperature until they reached a maximum value, and ...
Three model polymer-bonded explosive compositions were prepared to determine the effects of damage on their mechanical and thermal properties. The composites were damaged in a controllable manner such that three different levels of damage could be produced, and the strain on the samples could be determined. The samples differed in the size of the particles that they contained, and the sample that showed the largest decrease in mechanical properties occurring ...
Multi-walled carbon nanotube (MWCNT)/poly (methyl methacrylate) composites were prepared and their mechanical and physical properties were examined. An amphiphilic copolymer was used to aid in dispersing the MWCNTs throughout the composite. It was found that the use of this copolymer resulted in a good dispersal of the MWCNTs without drastically affecting the molecular weights of the composites, so it was concluded that the observed improvements in mechanical properties of ...
