Özet

Thermally conductive and three-dimensional (3D) printable polyether ether ketone (PEEK) composite filaments can be feedstock for fabricating thermal management systems through additive manufacturing. The study aims to improve the thermal conductivity of PEEK through hybridization for the 3D printing process. Three different fillers, namely (i) micron-sized hexagonal boron nitride (m-BN), (ii) carbon nanotubes (CNTs), and (iii) nano-sized hexagonal boron nitride (n-BN) were selected to fabricate hybrid CNTs/m-BN/PEEK and n-BN/m-BN/PEEK composites at various weight ratios via melt mixing process. The highest thermal conductivities were reported for 1.62 W/mK with 1 wt.% CNTs/ 30 wt.% m-BN, and 1.77 W/mK with 40 wt.% n-BN/m-BN (mass ratio, 3:1). TGA and DSC analyses showed that incorporation of hybrid fillers into the PEEK matrix slightly improved decomposition temperatures; however, hybrid fillers did not lead to a significant change in T_g. All CNTs/h-BN hybridized PEEK composites were manufactured in filament form and successfully 3D printed. The CNTs/h-BN PEEK composites would also be good candidates as lightweight advanced packaging materials for injection molding.
