Kim, Young-Kwan Jang, Hongje Kang, Kyungtae 2024-01-20T00:34:40Z 2024-01-20T00:34:40Z 2021-09-05 2017-08-31 0040-6090 https://pubs.kist.re.kr/handle/201004/122385 A facile fabrication strategy of multi-functional hybrid thin films of reduced graphene oxide (RGO) and TiO2 was developed by using layer-by-layer (LBL) assembly of titanium(IV) bis(ammonium lactato) dihydroxide (TALH) and polyallylamine grafted reduced graphene oxide (PAA-RGO) as negatively and positively charged components. The fabrication process of hybrid films was thoroughly characterized by using UV-vis spectroscopic, ellipsometric and atomic force microscopic analysis. This fabrication strategy provided precisely-controlled thickness, surface roughness through 1-10 LBL assembly cycles. By thermal treatment, the PAA-RGO and TALH in the hybrid films were respectively converted into RGO and TiO2 with the restoration of their electrical conductivity, UV-resistance and photo-catalytic self-cleaning properties.
