self cleaning properties mechanical stability and Adhesion strength of transparent photocatalytic tio2 zno coatings on polycarbonate
ACS Applied Materials & Interfaces, 2014Co-Authors: Razan Fateh, Ralf Dillert, Detlef W BahnemannAbstract:Transparent layers containing TiO2 have been intensively studied because of their interesting application potential including photocatalytically active and self-cleaning surfaces. In the present work, transparent TiO2–ZnO thin films on a SiO2 interlayer were successfully deposited on the surface of polycarbonate to provide polymeric sheets with a self-cleaning, superhydrophilic, and photocatalytically active surface layer. To ensure a Good Adhesion of the SiO2 interlayer, the polycarbonate sheets were first modified by irradiation with UV(C) light. The prepared films were characterized by UV/vis spectrophotometry, SEM, XRD, Raman spectroscopy, ellipsometry, and water contact-angle measurements. All prepared films are transparent, have thicknesses in the range between 120 and 250 nm, and possess superhydrophilic properties. Moreover, they exhibit Good Adhesion qualities as defined quantitatively by cross-cut tests. However, their mechanical strengths, checked by felt-abrasion tests, differ by changing the ...

preparation of polyaniline tio2 nanocomposite film with Good Adhesion behavior for dye sensitized solar cell application
Polymer Composites, 2013Co-Authors: Keisuke Kawata, Kavirajaa Pandian Sambasevam, Sook Wai Phang, Noriyuki KuramotoAbstract:In this study, novel Polyaniline (PAni)/TiO2 nanocomposites were applied on fluoride-doped tin oxide (FTO) glass to act as an efficient counter electrode in dyesensitized solar cell (DSSC) application. PAni/TiO2 nanocomposites were synthesized via chemical oxidation process using di-2-ethylhexylsulfosuccinate sodium salt (NaDEHS) as dopant. The nanocomposites were characterized using fourier transform infrared and ultraviolet-visible spectrometers. In the application of PAni as the counter electrode in the solar cell, the film showed poor Adhesion on the FTO glass. Palm oilbased alkyd was introduced into the nanocomposite mixture to improve the Adhesion of the film. The findings in the work show that strong Adhesion of PAni on FTO glasses has led to higher incident photon to current conversion efficiency (IPCE) in solar cell. The short circuit current (Jsc), Voc (open circuit voltage), and IPCE of the resulted PAni/TiO2 counter electrode with Good Adhesion in DSSC are 15.8 mA/cm 2 , 670 mV, and 3.0%, respectively. POLYM.
