Lsr thermal conductivity
Web1 jun. 2014 · Thermal diffusivity is commonly measured by laser flash analysis (LFA) techniques. In the early 1960s, Parker et al. developed a method to determine thermal diffusivity, α, from the time it takes for the rear face of a sample to reach 50% of the maximum temperature increase, t50%, from an energy pulse on the front face using Eq. … Web22 jun. 2015 · To improve the thermal and mechanical properties of liquid silicone rubber (LSR) for application, the graphene oxide (GO) was proposed to reinforce the LSR. The GO was functionalized with triethoxyvinylsilane (TEVS) by dehydration reaction to improve the dispersion and compatibility in the matrix.
