Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The transient technique is the commercial method used to test the thermal conductivity, thermal diffusivity, and specific heat of solids. With the instrument, a double spiral nickel sensor is sandwiched between two homogenous samples, and as the sensor pulses electrical currents through the sample, it simultaneously measures how long it takes for the temperature of the sample to increase. This method is typically used on glasses, insulating materials, and polymer ...
Polyoxymethylene (POM) is a resistant polymer with wide applications in aerospace, automotives, and biomedicine. However, it falls short when used in the manufacturing of sliding parts. In this study, copper particles and polytetrafluoroethylene (PTFE) powder were incorporated into POM to improve the thermal conductivity of the polymer composite while reducing the friction coefficient. A thermal analyzer was used to measure the thermal conductivity of POM composites using the transient plane ...
In this paper, natural rubber (NR)/graphene (GE) composites were prepared using an ultrasonically-assisted latex mixing and in situ reduction (ULMR) process. A thermal constants analyzer measured the thermal conductivity of the NR/GE composites using the transient plane source (TPS) method. Results showed that GE had a good thermal conductivity, and can be used as a thermal conductivity enhancer in polymers....
The authors have developed a method for the functionalization of single-walled carbon nanotubes (SWCNTs). The functionalization of the SWCNTs is useful in helping to produce a better dispersion of nanotubes throughout a polymer matrix. Better dispersion of nanotubes was thought to result in an improvement in the mechanical, electrical, and thermal properties of nanocomposite polymers. It was determined that the method produced effective surface modification of the nanotubes. The elastic ...
The authors prepared silica aerogel/polyurethane composites by two different methods for the comparison of the two methods. The objective was to study the thermal insulation and hydrophobic properties of the composites to evaluate their potential for use as fabric membranes. It was found that the composites are better thermal insulators than polyurethane alone, and that they also have improved hydrophobic properties. It was also determined that the thermal conductivities ...
