“…3D printing technology can facilitate the uniform dispersion of thermally conductive fillers within the polymer matrix, reducing the defects caused by filler agglomeration, thereby diminishing phonon scattering and enhancing the thermal conductivity of the composites. Lin et al 169 utilized VP 3D printing technology to uniformly disperse hBN thermally conductive fillers into epoxy acrylate (EA) resin. The results showed that when the mass fraction of hBN was 30 wt%, the λ of the hBN/EA composites reached 1.60 W m –1 K –1 , which was 6.8 times higher than that of pure EA (0.21 W m –1 K –1 ).…”

The potential of three‐dimensional (3D) printing technology in the fabrication of advanced polymer composites is becoming increasingly evident. This review discusses the latest research developments and applications of 3D printing in polymer composites. First, it focuses on the optimization of 3D printing technology, that is, by upgrading the equipment or components or adjusting the printing parameters, to make them more adaptable to the processing characteristics of polymer composites and to improve the comprehensive performance of the products. Second, it focuses on the 3D printable novel consumables for polymer composites, which mainly include the new printing filaments, printing inks, photosensitive resins, and printing powders, introducing the unique properties of the new consumables and different ways to apply them to 3D printing. Finally, the applications of 3D printing technology in the preparation of functional polymer composites (such as thermal conductivity, electromagnetic interference shielding, biomedicine, self‐healing, and environmental responsiveness) are explored, with a focus on the distribution of the functional fillers and the influence of the topological shapes on the properties and functional characteristics of the 3D printed products. The aim of this review is to deepen the understanding of the convergence between 3D printing technology and polymer composites and to anticipate future trends and applications.image

Owing to the rapid advancement in electronic devices, thermal interface materials have been introduced to solve the thermal dissipation and electrical insulation problems in electronic parts and packaging materials. In this study, flexible thermally conductive acrylate‐based composites were fabricated via 3D vat photopolymerization. The effects of amine functional groups on the thermal and mechanical properties of acrylate polymers were explored. Surface‐treatment agents, namely, (3‐aminopropyl)triethoxysilane (APTES) and octadecylamine (ODA), were selected to enhance the poor dispersibility of fillers in the resin matrix caused by aggregation. The APTES‐treated carbon nanotube (CNT)–boron nitride (BN) hybrid composite exhibited the highest thermal conductivity of 0.990 W m−1 K−1, which was remarkably 482.35% higher than that of the matrix owing to the addition of 30 wt% BN, 0.5 wt% CNTs, and APTES treatment. The ODA‐treated CNT composite, which contained only 0.5 wt% CNTs, exhibited a thermal conductivity of 0.540 W m−1 K−1, which was 217.65% higher than that of the matrix. The electrical insulation properties of the composites were characterized, and the composites exhibited low electrical conductivity as electrical insulation materials. The advantages of the 3D‐printed flexible thermally conductive acrylate polymers usher in a new era of using polymer composites to address heat dissipation problems in complex structures.

“…When the Al 2 O 3 filling amount was 26.67 wt% and BN filling amount is 13.33 wt%, the thermal conductivity of the composite material was improved to 1.192 W/(m·K), which was 654.9% of that of pure epoxy resin 45 . Lin et al used 3D printing technology to fill 15 wt% h‐BN and 30 wt% AlN blend into liquid photosensitive resin, resulting in an increase in the thermal conductivity of the composite material to 1.31 W/(m·K) 46 . Feng et al filled Al 2 O 3 and BN blended into silicone rubber by hot pressing method.…”

As an emerging field of current technological development, the heat dissipation performance of electronic packaging materials has become the key to determining product reliability. Therefore, the applied thermal interface materials (TIMs) need to simultaneously meet the performance indicators of thermal conductivity, mechanics, and insulation. Although BN had excellent in‐plane thermal conductivity and insulation performance, it is currently difficult to achieve vertical orientation of powder which leads the layered powder cannot complete a continuous and effective heat transfer path along the Z‐axis direction inside the composite material. In order to solve the above two problems, out‐of‐plane thermal conductive composite was prepared by introducing magnetic oriented method. In order to comprehensively evaluate the thermal conductivity, mechanical and electrical properties, BN@Fe3O4/EP magnetic oriented composites were compared with BN@PDA‐Al2O3/EP composite prepared by mechanical blending method. The vertical thermal conductivity of the magnetic oriented composite material was 2.24 W/(m·K) at 30 vol%, which was 3.39 times that of the blended composite material and 12.4 times that of pure EP. This proves that the magnetic oriented composite materials prepared by the research institute can meet the vertical heat transfer needs in the field of electronic packaging and have high research value in this area.Highlights BN@Fe3O4 core–shell particles were prepared with both thermal conductivity and magnetic controllability. The thermosetting composites were prepared by heated through preliminary gel point and then cured at high temperature. The orientation of powder inside the matrix was constructed, resulted in excellent out‐of‐plane heat transfer performance. Comparisons were made between various properties of magnetic oriented materials and conventional blend materials. The magnetic orientation method is feasible in the field of electronic packaging.
