Effective Manner

The transportation phenomenon of ethanol in pre-deformed poly(methyl methacrylate) (PMMA) is systematically investigated. Two different phenomena simultaneously occur during this process. One is shape recovery, which is resulted from the ethanol induced softening and plasticization of PMMA. The other is swelling, which is produced by the ethanol induced molecular relaxation. Based on this study, a novel surface patterning method is proposed to fabricate PMMA microlens arrays in a simple and cost-effective manner.
