摘要

Abstract

This work proposes a facile fabrication strategy for thermally conductive graphite nanosheets/poly(lactic acid) sheets with ordered GNPs (o-GNPs/PLA)

via

fused deposition modeling (FDM) 3D printing technology. Further combinations of o-GNPs/PLA with Ti

films prepared by vacuum-assisted filtration were carried out by “layer-by-layer stacking-hot pressing” to be the thermally conductive Ti

/(o-GNPs/PLA) composit

es with superior electromagnetic interference shielding effectiveness (EMI SE). When the content of GNPs was 18.60 wt% and 4 layers of Ti

(6.98 wt%) films were embedded

the in-plane thermal conductivity coefficient (

) and EMI SE (EMI SE

) values of the thermally conductive Ti

/(o-GNPs/PLA) composites significantly increased to 3.44 W·m

–1

·K

–1

and 65 dB (3.00 mm)

increased by 1223.1% and 2066.7%

respectively

compared with

(0.26 W·m

–1

·K

–1

) and EMI SE

(3 dB) of neat PLA matrix. This work offers a novel and easily route for designing and manufacturing highly thermally conductive polymer composites with superior EMI SE for broader application.
