Over a short period of time, electronic assemblies have been dramatically developed with smaller size and lighter weight and 3D printing plays a crucial role in their future production. However, it is difficult to develop epoxy resins and other thermoset resins for this process because of the polymer's liquid state during processing. This work uses a UV curing technique for making flexible epoxy/multi-walled carbon nanotubes (MWCNTs) composites that are suitable for future 3D printing applications. The synthesized carbazole-coated TiO₂ nanoparticles, used as a photosensitizer, were characterized by their photoabsorbance, morphology, and surface property before use. The results indicated that the TiO₂ nanoparticles coated with 75 wt% carbazole were appropriate for UV-cured flexible epoxy/MWCNT composites because of its fast cure kinetics after irradiation by a UV light source. The epoxy/MWCNT composites displayed low tensile properties because of the agglomeration of MWCNTs inside the epoxy matrix. In addition, the epoxy/MWCNT composites showed slightly lower thermal expansion with high electrical properties with a large amount of MWCNTs in the epoxy composites.

在很短的时间内，电子组件得到了显着发展，尺寸更小、重量更轻，3D 打印在其未来的生产中起着至关重要的作用。然而，由于聚合物在加工过程中呈液态，因此很难为该工艺开发环氧树脂和其他热固性树脂。这项工作使用紫外线固化技术来制造适用于未来 3D 打印应用的柔性环氧树脂/多壁碳纳米管 (MWCNT) 复合材料。合成的咔唑包覆的TiO ₂纳米颗粒用作光敏剂，在使用前通过其光吸收、形貌和表面性质进行表征。结果表明, TiO ₂涂有 75 wt% 咔唑的纳米粒子适用于紫外线固化的柔性环氧树脂 / MWCNT 复合材料，因为它在被紫外线光源照射后具有快速固化动力学。环氧树脂/多壁碳纳米管复合材料由于多壁碳纳米管在环氧树脂基体内的团聚而表现出低拉伸性能。此外，环氧/多壁碳纳米管复合材料表现出略低的热膨胀和高电性能，环氧复合材料中含有大量的多壁碳纳米管。
