PMMA-based Stimuli-responsive Flexible Thin-films

Abstract

Low-cost flexible thin-films exhibiting stimuli-responsive properties were fabricated on poly(methyl methacrylate) (PMMA) as the base supporting material. Labeling of this transparent thermoplastic with Congo red diazo dye revealed its simultaneous pH-responsive and temperature-responsive abilities. UV, FT-IR, and film stability studies identified the role of the dye and the polymer in the flexible thin-film stimuli-responsive behavior. This film is promising for future applications.

Ultra-stable dye-filled polytetrafluoroethylene thin films

“…Various sensors made from the organic thin films are described in literature, for example, in the reviews [1,2]. Novel research in this field are concerned not only dye-in-polymer film [3], but three component nanocomposite film as well [4]. In many cases this is a good method to prevent dye molecule aggregation and keep film with necessary optical properties for a long time.…”
