Highly transparent and multifunctional polymer nanohybrid film with superhigh ZnO content synthesized by a bulk polymerization method / Hai-Tao Liu in Industrial & engineering chemistry research, Vol. 51 N° 19 (Mai 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 19 (Mai 2012) . - pp. 6753-6759 Titre : Highly transparent and multifunctional polymer nanohybrid film with superhigh ZnO content synthesized by a bulk polymerization method Type de document : texte imprimé Auteurs : Hai-Tao Liu, Auteur ; Xiao-Fei Zeng, Auteur ; Hong Zhao, Auteur Année de publication : 2012 Article en page(s) : pp. 6753-6759 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Polymerization Résumé : Highly transparent and multifunctional ZnO/poly(n-butyl methacrylate) (ZnO/PBMA) nanohybrid films with superhigh contents of ZnO nanoparticles (NPs) were synthesized by a bulk polymerization method. The structure; morphology; and optical, mechanical, and thermal properties of the obtained nanohybrid films were studied. ZnO NPs were dispersed uniformly and retained their original size (4―6 nm) in the PBMA matrix without any aggregation. The ZnO/PBMA nanohybrid films allowed more than 90% of visible light at 550 nm to pass and maintained almost the same high transparency as pure PBMA film even when the ZnO NP content was as high as 60 wt %. The nanohybrid films embedded with ZnO NPs exhibited significantly enhanced multifunctional performance, including excellent UV-shielding properties, good thermal stability, high surface hardness, and desired flexibility. In particular, the coefficient of thermal expansion (CTE) of the nanohybrid films dearly decreased to 193 from 325 ppm/K for pure PBMA below the glass transition temperature (Tg) and strikingly decreased from 5378 to 1373 ppm/K after the glass transition. The ZnO/polymer nanohybrids synthesized in this work are promising for the fabrication of optical devices with high transparency, such as flexible displays, optical filters, and flexible solar cells.
