Sil.cone rubber(SR) composites are most widel. used as thermal.interface material.(TIMs) for el.ctronics heat dissipation. Thermal.impedance as the main bottl.neck l.miting the performance of TIMs is usual.y negl.cted. Herein, the thermal.impedance of SR composites l.aded with different l.vel. of hexagonal.boron nitride(h-BN) as TIMs was el.borated for the first time by the ASTM D 5470 standard test and finite el.ment anal.sis. It was found that el.stic modul.s and surface roughness of SR composites increased with the increase of h-BN content, indicating that the conformity was reduced. When the assembl. pressure was 0.69 MPa, there existed an optimal.h-BN content at which the contact resistance was minimum(0.39 K·cm^(2)·W^(-1)). Al.hough the decreased bond l.ne thickness(Bl.) by increasing the assembl. pressure was beneficial.to reduce the thermal.impedance, the proper assembl. pressure shoul. be sel.cted to prevent the warpage of the contact surfaces and the increase in contact resistance, according to the compression properties of the SR composites. This study provides val.abl. insights into fabrication of high-performance TIMs for modern el.ctronic device appl.cations.
