摘要：

以酚醛树脂(PF)为热交联物质, 添加交联剂2,4,6-三[双(甲氧基甲基)氨基]-1,3,5-三嗪和产酸剂二苯基碘鎓六氟磷酸盐, 表面带有精细微纳米图案的聚二甲基硅氧烷(PDMS)作为印章, 采用热微接触印刷(hot μCP)技术制备热交联聚合物的微纳米图案. 通过扫描电子显微镜(SEM)和接触角测量仪对精细结构图案进行表征. 结果表明, 这种简单、快速、低成本的hot μCP法能够成功地实现热交联聚合物的图案化, 且最小尺度可接近100 nm.

Abstract:

We added 2,4,6-tris[bis(methoxymethyl)-amino]-1,3,5-triazine as a crosslinking agent and diphenyliodonium hexafluorophosphate as an acid generator to phenolic resin, which is a thermosensitive polymer. A topographically patterned polydimethylsiloxane (PDMS) stamp was used to obtain micro/nano structures by hot microcontact printing (hot μCP). The fine pattern was characterized using scanning electron microscopy (SEM) and a contact angle measurement. We found that hot μCP is a fast, simple, and inexpensive technique that can produce thermal cross-linking patterns and the obtained minimumsize is close to 100 nm.
