| Abstract | DCPDCE/BADCy hybrid resin and BN fillers were performed to fabricate the thermally conductive BN/DCPDCE/BADCy composites. When the molar ratio of DCPDCE/BADCy was 0.4/0.6, the dielectric constant (epsilon) and dielectric loss tangent (tgδ) value of the DCPDCE/BADCy hybrid resin was decreased to 2.92 and 5.08 x 10-3, respectively. Impact and flexural strength was increased to 10.7 kJ/m2 and 100.7 MPa, respectively. And the heat-resistance index (THRI) was 201.6 ℃. Furthermore, the thermally conductive coefficient (λ) of the BN/DCPDCE/BADCy composite with 30 wt% BN fillers was improved to 0.64 W/mK, about 3 times in comparison to that of pristine DCPDCE/BADCy hybrid resin. Compared to that of Maxwell and Russell models, our proposed thermally conductive model could predict the experimental lambda values more precisely. T-HRI value was enhanced from 201.6 ℃ (Pristine DCPDCE/BADCy hybrid resin) to 206.6 ℃. Moreover, the BN/DCPDCE/BADCy composite with 10 wt% BN presented the optimal impact strength (11.7 kJ/m2) and flexural strength (108.4 MPa). |
