Synergistic effects of oriented AlN skeletons and 1D SiC nanowires for enhancing the thermal conductivity of epoxy composites

Enhancing the Thermal Conductivity of Epoxy Composites via Constructing Oriented ZnO Nanowire-Decorated Carbon Fibers Networks

“…The subsequent freeze-drying process took place under a vacuum (~10 Pa, 60 • C), where the ice crystals sublimated directly into water vapor and escaped, leaving oriented voids, while the billet retained its skeleton with an oriented structure without collapsing. As a result, the three-dimensional oriented CF skeletons with pore channels arranged from bottom to top were retained [37,38]. Figure 4d-f further show the SEM images and EDS mapping of Zn element for CF@ZnO-0.10 skeletons prepared from slurries with 40 wt% solid content.…”

Boosting the in-plane thermal conductivity of nanofibrillated cellulose films: alignment engineering of cross-linked AlN whiskers

“…AlN has been considered as a promising thermally conductive filler due to its excellent properties, such as ultrahigh theoretical thermal conductivity of 320 W m −1 K −1 , high electrical resistivity, low dielectric constant, low thermal expansion coefficient, and non-toxicity. 21 For example, Zhao et al 22 reported an epoxy-based composite with stearic acid-modified AlN particles as the primary filler and silicon carbide nanowires (SiCNWs) as the secondary filler, which showed a maximum thermal conductivity value of 2.56 W m −1 K −1 in the vertical direction at a filler ratio of 55 vol%. Wu et al 23 obtained three-dimensional AlN skeletons (3D-AlNNS) by the ice template method, and subsequently prepared the AlN/epoxy composites by vacuum infiltration.…”
