| Abstract:Facing the development of very large-scale integration circuits and the harsh application environment, starting from market
demand, as two-dimensional hybrid materials, MOFs (UIO-66) was coated on polyhydroxy carbon nanotubes surface through in-situ
growth methods. Then mix UMT nanomaterials into epoxy matrix (EP) to obtain UMTE composite materials. The results show that
0.5% UMTE composites have a dielectric constant reduced by 8.7% compared with pure EP. The dielectric loss of composites is always
lower than 0.035 (100~107 Hz). When the content of nano-filler reaches 2%, the thermal conductivity of UMTE composites is increased
by 233%. In conclusion, it has good electrical insulation and heat dissipation. UMTE composites provide new research ideas for the
design of epoxy resin materials suitable for the microelectronics industry, which have low dielectric constant, low dielectric loss and
high thermal conductivity. |
