CHT-15: Investigation of Phonon Transport and Thermal Boundary Conductance at Interface of SWCNT and Poly (Ether-Ketone)
RESUMO
The thermal and electrical applications of many polymers commonly used in commercial and defense applications are scarce due to their low conductivities. The addition of carbon nano-structures such as carbon nanotubes (CNTs) in the polymer matrix can lead to significant improvement in the thermal and electrical properties of the resulting nano-composite. An exceptional improvement in the electrical and thermal conductivity of fibers made by poly (ether) ketone (PEK) grafted few walled carbon nanotube has been observed in the experiments. However, the thermal interaction of CNT and PEK molecules has not been understood yet. In this study, the interface thermal boundary conductance between SWCNT and PEK were estimated using two different molecular dynamics method. The modifications in CNT dispersion curves due to the interaction with PEK were studied using spectral energy density and the energy transport across the interface were investigated through the decay of spectral temperature in different frequency bands of CNT.
