The thermal, mechanical and electrical properties of nanocomposites with carbon nanoplate(CNP) and carbon nanotube(CNT) were measured. Fillers were added to diglycidyl ether of 4,4′-biphenol(DGEBP) and 4,4′-diglycidyloxy-3,3′,5,5′-tetramethyl biphenyl(YX 4000H) epoxies. To improve their properties, the hybridized nanofillers with a mixture of CNP and CNT were added to the epoxy matrix. The TC of the DGEBP epoxy shows the higher than YX 4000H. Because the steric hinderance of YX 4000H have a higher than that of DGEBP, it makes more than a pi-pi stacking with mesogen groups. The hybridized nanofillers at lower filler contents of CNT were added to epoxy matrix, because electrical properties of nanocomposites with CNT have a lower electrical percolation threshold compared with that of CNP. Results showed that the addition of minimal amounts of a high aspect ratio of CNT with CNP enhance the electrical properties and preserved the their properties of intrinsic nanocomposites. |
