摘要

低成本的紫外臭氧箱在改善 PET 基底的附着力方面显示出良好的效果。对曝光时间和温度的应用表明，曝光 2 小时后，透射率保持不变，接触角减少了 30°。这一过程使 PET 基底从疏水变为亲水，有利于水基材料的沉积。傅立叶变换红外光谱分析也证明，紫外臭氧照射会促进 PET 基底上的酯基和对苯二甲酸酯基发生永久性变化。原子力显微镜分析表明，薄膜的粗糙度对基底的亲水性有很大影响。薄膜的亲水特性在 24 小时内保持稳定，但在关闭紫外线照明后的第一个小时内，薄膜的亲水特性会降低 15°。

UV-Ozone Chamber Assembled for Treatment and Contact Angle Reduction on PET Surfaces

A low-cost UV-Ozone chamber showed promising results for improving adhesion on PET substrates. Exposure times and temperatures were applied, revealing that with 2 hours of exposure, the transmittance remained intact, and the contact angle was reduced by 30°. This process makes the PET substrate change from hydrophobic to hydrophilic, favoring the deposition of water-based materials. It was also proven, by FTIR analysis, that UV-Ozone exposure promotes permanent changes at ester and terephthalate groups on PET substrates. The AFM analysis demonstrated that the films' roughness significantly affects the substrates' hydrophilicity. The film's hydrophilic characteristics remain stable for more than 24 hours; however, a reduction of 15° is observed in the first hour after UV lighting is switched off.

期刊介绍： IEEE Instrumentation & Measurement Magazine is a bimonthly publication. It publishes in February, April, June, August, October, and December of each year. The magazine covers a wide variety of topics in instrumentation, measurement, and systems that measure or instrument equipment or other systems. The magazine has the goal of providing readable introductions and overviews of technology in instrumentation and measurement to a wide engineering audience. It does this through articles, tutorials, columns, and departments. Its goal is to cross disciplines to encourage further research and development in instrumentation and measurement.
