摘要

采用三甲基铝(III)和水原子层沉积(ALD)工艺，在80℃下用氧化铝(Al2O3)包裹3d打印的丙烯腈-丁二烯-苯乙烯(ABS)聚合物结构，得到了203nm的薄膜，每循环生长1.35 Å。在抗溶剂性实验中，该薄膜是一种粘附良好的保护覆层，用于防止ABS与丙酮蒸气发生反应。划痕试验不能去除聚合物表面的覆盖层，在初始变形和结构完全崩溃之前，它们的丙酮蒸气阻力分别增加了50%和32%。更激进的胶带测试导致了保护涂层的分层。这个概念验证实验展示了3D打印与ALD涂层相结合如何改变复杂聚合物结构的化学特性。

Modified 3D-printed architectures: Effects of coating by alumina on acrylonitrile butadiene styrene

3D-printed acrylonitrile butadiene styrene (ABS) polymer structures were coated with alumina (Al2O3) using the trimethylaluminum(III) and water atomic layer deposition (ALD) process at 80 °C, which resulted in a 203 nm thin film with a 1.35 Å growth per cycle. This thin film was a well-adhered protective overcoating on ABS to prevent reaction with acetone vapors in a solvent resistance experiment. Scratch tests were not able to remove the overcoating from the polymer surface, which provided a 50% and 32% increase in acetone vapor resistance before initial deformation and complete structure collapse, respectively. A more aggressive tape test caused delamination of the protective coating. This proof-of-concept experiment demonstrates how 3D printing combined with ALD overcoating can alter the chemical characteristics of complex polymer architectures.
