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.

Key words: Micro/nano structure, Thermal cross-linking, Printing, Polymer, Phenolic resin
