Tuning the surface wettability of photoresist film is a critical consideration in its application of microfluidics. In this work, the surface wettability tuning of acrylic resin photoresist by oxygen plasma or ultra-violet\/ozone, and its aging performance in different atmospheres, were systematically studied. The chemical and physical characterizations of the surfaces before and after modification show a dramatic decrease in the C\u2013C group and increase in surface roughness for oxygen plasma treatment, while a decrease of the C\u2013C group was found for the UV\/ozone treatment. The above difference in the surface tuning mechanism may explain the stronger hydrophilic modification effect of oxygen plasma. In addition, we found an obvious fading of the wettability tuning effect with an environment-related aging speed, which can also be featured by the decrease of the C\u2013C group. This study demonstrates the dominated chemical and physical changes during surface wettability tuning and its aging process, and provides basis for surface tuning and the applications in microfluidics.<\/jats:p>","DOI":"10.3390\/s21144866","type":"journal-article","created":{"date-parts":[[2021,7,19]],"date-time":"2021-07-19T10:07:37Z","timestamp":1626689257000},"page":"4866","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Surface Wettability Tuning of Acrylic Resin Photoresist and Its Aging Performance"],"prefix":"10.3390","volume":"21","author":[{"given":"Yingying","family":"Dou","sequence":"first","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Optical Information Materials and Technology & Institute of Electronic Paper Displays, South China Academy of Advanced Optoelectronics, South China Normal University, Guangzhou 510006, China"},{"name":"Key Laboratory for Polymer Composite & Functional Materials of Ministry of Education, School of Materials Science and Engineering, Sun Yat-sen University, Guangzhou 510006, China"},{"name":"National Center for International Research on Green Optoelectronics, South China Normal University, Guangzhou 510006, China"}]},{"given":"Fahong","family":"Li","sequence":"additional","affiliation":[{"name":"National Center for International Research on Green Optoelectronics, South China Normal University, Guangzhou 510006, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5838-7485","authenticated-orcid":false,"given":"Biao","family":"Tang","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Optical Information Materials and Technology & Institute of Electronic Paper Displays, South China Academy of Advanced Optoelectronics, South China Normal University, Guangzhou 510006, China"},{"name":"National Center for International Research on Green Optoelectronics, South China Normal University, Guangzhou 510006, China"}]},{"given":"Guofu","family":"Zhou","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Optical Information Materials and Technology & Institute of Electronic Paper Displays, South China Academy of Advanced Optoelectronics, South China Normal University, Guangzhou 510006, China"},{"name":"National Center for International Research on Green Optoelectronics, South China Normal University, Guangzhou 510006, China"},{"name":"Shenzhen Guohua Optoelectronics Tech.
