Aerogels have a wide range of properties that make them effective thermal insulators. However, these properties are lost when the materials absorb too much water. The goal of this experiment was to determine how temperature and humidity affect the insulative properties of silica nano-porous aerogels. A thermal constants analyzer measured the thermal conductivity of moist silica nano-porous materials using the transient plane source (TPS) method. Results showed that the thermal ...
Conductive polymer composites (CPCs) contain high concentrations of carbon nanotubes (CNTs) to maximize electrical conductivity. However, high nanoparticle concentrations degrade other important properties of CPCs. This study produced CPCs using ultrahigh molecular weight polyethylene (UHMWPE) fillers in place of CNTs in an attempt to maintain important physical and mechanical properties. A thermal analyzer measured the thermal conductivity of the CPC samples using the transient plane source (TPS) method. Results showed ...
This study aimed to enhance the thermal and mechanical properties of polyethylene (PE)/boron nitride (BN) composites by manipulating the BN concentrations in the matrix and by applying shear fields in laminating-multiplying elements (LMEs). A thermal constants analyzer measured the thermal conductivity of the PE/BN composites using the transient plane source (TPS) method. Results showed that the thermal conductivity of the composites increased with BN concentration. As well, the ...
In this study, aluminum nitride was treated with silane in an attempt to improve the performance of polyetherimide (PEI) composites. Various properties of the modified AlN/PEI composites were examined including the thermal conductivity by way of a thermal analyzer based on the transient plane source (TPS) method. Results showed that the AlN filler improved dispersion and interface of the matrix which enhanced the thermal conductivity of the PEI composites....
Polylactide (PLA) is a biodegradable polyester with a wide range of applications in transportation and construction industries. In this study, the physical and mechanical properties of low void fraction PLA foams and high void fraction PLA composite foams were examined after their fabrication using the high-pressure foam injection molding (HPFIM) process. A thermal constants analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results ...
