Metallopolymer Capacitor in “One Pot” by Self-Directed UV-Assisted Process

Abstract

Silver metalized methacrylate films are prepared by single-step UV curing process with good conductivity on both sides. The major component of the composite is Bisphenol A ethoxylate dimethacrylate, which can be photopolymerized by a photoreactive initiator under UV light. Under the same conditions of UV irradiation, silver ions are deposited as metal nanoparticles while the pyrrole is oxidized to polypyrrole. The migration of silver ions and pyrrole toward both surfaces during polymerization leads to the formation of a metallo-polymer capacitor. The composite films are characterized by SEM-EDX and electrical measurements for possible applications as capacitors in flexible and/or nonplanar electronics.

Preparation and application of conducting polymer/Ag/clay composite nanoparticles formed by in situ UV-induced dispersion polymerization

“…The electrical conductivity of the nanocomposite with varied concentration of ATP clay is summarized in Table 1 . The maximum electrical conductivity was 0.442 S/cm for S-3, which was comparable with other reported values for similar PPy/Ag/insulated substrate composites 5 7 13 19 . The electrical conductivity of the nanocomposite that was attributed to the presence of doped PPy and metallic Ag particles, increased firstly and then decreased with the increment of ATP concentration.…”

“…PPy/Ag/ATP composite nanoparticles were successfully prepared by UV-induced dispersion polymerization with the help of AgNO 3 . Our work is compared with other reports that used AgNO 3 as an oxidant to perform polymerization of pyrrole with or without UV light 13 15 17 18 19 . Significantly, in this work UV-induced polymerization of pyrrole using AgNO 3 as photoinitiator in ATP colloid can be finished in 10 min with high yield (~80%), demonstrating this strategy is facile and efficient.…”

“…reported a method to prepare PPy/Ag/methacrylate polymer film by UV-induced polymerization using AgNO 3 as metal precursor and oxidant for pyrrole and Darocur 1173 as photoinitiator for bisphenol A ethoxylate dimethacrylate. During polymerization, Ag + and pyrrole migrated toward both surfaces to form a metallo-polymer capacitor 19 .…”

Hybrid and Hierarchical Composite Materials

“…Common systems employed in such processes include, among others, acrylates (Sangermano et al 2009;Chibac et al 2012), methacrylates (Sangermano et al 2011) epoxy- (Kahraman et al 2009) and vinyl ether-based systems (Sangermano et al 2007) combined with metal oxide nanoparticles including silica, titania and alumina (Sangermano et al 2011), clays (Ceccia et al 2008, and MNPs (Ijeri et al 2010).…”
