论文摘要
原子层沉积的过程与自组装的单层相结合，用于研究聚氨酯涂料表面的可能修饰。首先，我们使用ALD工艺在低至40度的温度下生产这些表面的薄且均匀的AL2O3涂层。然后，我们成功地实现了在Al2O3涂层涂料样品中添加16磷核酸六核酸SAM。 AL2O3涂层将PUR表面的接触角从110度降低至10度，并伴随着初始疏水性，但是不稳定。随着时间的推移。在AL2O3上添加SAMS会导致其接触角持续降低至60至70度，样品的老化显示，进一步降低至25至40度。 AL2O3 16 PHA涂层在天气量量表中的测试也揭示了其耐用性，即使在恶劣的户外条件下也是如此。这些实验结果表明，通过将ALD与SAM结合在一起，可以生产具有经过随时间稳定的经过修改的亲水性或疏水性能的耐用涂层。使用具有不同端组的SAM的使用可能允许对涂层润湿特性进行微调
A process of atomic layer deposition combined with self assembled monolayers was used to investigate the possible modification of polyurethane paint surfaces. First, we used an ALD process to produce thin and uniform Al2O3 coatings of these surfaces at temperatures as low as 40 degrees. We then successfully achieved the addition of 16phosphonohexadecanoic acid SAMs to the Al2O3 coated paint samples. Al2O3 coatings reduced the contact angle of the PUR surfaces from 110 to 10 degrees, accompanied by an initial hydrophobicity which however was not stable. over time. Addition of SAMs on the Al2O3 induced a sustained reduction in their contact angles to 60 to 70 degrees, and aging of the samples revealed a further decrease to 25 to40 degrees. Testing of the Al2O3 16 PHA coating in a Weather OMeter revealed its durability even under harsh outdoor conditions. These experimental results show that by combining ALD with SAMs it is possible to produce durable coatings with modified hydrophilic or hydrophobic properties that are stable over time. The use of SAMs with different end groups may allow fine tuning of the coating wetting properties
