Fluorescence study of effect of particle size in PS latex/Al2O3 nanocomposite films
Authors:
Publisher and Date:(MANEY PUBLISHING, 2015)Steady state fluorescence and BioUV-Visible techniques were used to study film formation of polystyrene (PS) latex and Al2O3 composites depending on PS particles size and Al2O3 content. Two film series (SmPS/Al2O3 and LgPS/Al2O3) were prepared covering PS sphere (SmPS: 203 nm

Fluorescence Study of Film Formation from PS Latex-TiO2 Composites: Effects of TiO2 Content Film Thickness and Particle Size
Authors:
Publisher and Date:(Amer Scientific Publishers, 2015)Steady-state fluorescence (SSF) technique in conjunction with UV-visible (UVV) technique atomic force microscope (AFM) and scanning electron microscope (SEM) is used for studying film formation from TiO2 covered polystyrene (PS) latex particles. The effects of TiO2 content film thickness and PS particle size on film formation and structure properties of PS/TiO2 composites are studied. For this purpose in the first part two different sets of PS films with thicknesses of 5 and 20 mu m were prepared ...

Fluorescence study of film formation from PS/Al2O3 nanocomposites
Authors:
Publisher and Date:(Elsevier Science, 2014)Steady state fluorescence (SSF) and UV-vis (UVV) techniques were used to study the film formation behavior of pyrene (P) labeled polystyrene (PS) latex and Al2O3 (PS/Al2O3) composites depending on PS particles size and Al2O3 content. The close-packed arrays of PS spheres (SmPS: 203 nm ; LgPS: 382 nm) templates on clean glass substrates were covered with various layers of Al2O3 by dip-coating method. Two different film series (SmPS/Al2O3 and LgPS/Al2O3) were prepared in various Al2O3 layer content. ...

Particle Size Effect on the Film-Forming Process of PS/PBA Composite Latexes
Authors:
Publisher and Date:(John Wiley & Sons Inc, 2010)In this work the effect of hard particle size and blend ratio on the film formation behavior of hard polystyrene (PS) and soft poly(n-butyl acrylate) (PBA) latex blends was studied by means of steady-state fluorescence and UV-visible techniques in conjunction with atomic force microscopy. Three different sets of latexes were synthesized: PBA latex (diameter 97 nm) pyrene (P)-labeled large PS (LgPS

Spectroscopic study of film formation from polystyrene latex/TiO2 nanocomposites prepared by dip-coating method
Authors:
Publisher and Date:(Wiley-Blackwell, 2014)In this study we investigated the influence of TiO2 content and thickness of polystyrene (PS) template on film-formation behavior of PS/TiO2 composites using fluorescence and ultraviolet-visible techniques in conjunction with scanning electron microscopy. Films were prepared by coating PS templates with various layers of TiO2 using dip-coating method. The results showed that PS latexes present complete film formation on top surface of composites. After extraction of PS a well-defined interconnected ...

Study of Film Formation From PS Latex/TiO2 Nanocomposites
Authors:
Publisher and Date:(Wiley-Blackwell, 2014)In this work we investigated the film formation from polystyrene (PS) latex/TiO2 nanocomposites using the steady state fluorescence (SSF) and UV-vis (UVV) techniques depending on PS particle size and TiO2 content. The structural properties of films were characterized by scanning electron microscope (SEM). The films were prepared from pyrene (P)-labeled PS particles (SmPS: 203 nm

The effect of film thickness and TiO2 content on film formation from PS/TiO2 nanocomposites prepared by dip-coating method
Authors:
Publisher and Date:(Hindawi Publishing Corporation, 2012)Steady-state fluorescence (SSF) technique in conjunction with UV-visible (UVV) technique and atomic force microscope (AFM) was used for studying film formation from TiO2 covered nanosized polystyrene (PS) latex particles (320 nm). The effects of film thickness and TiO2 content on the film formation and structure properties of PS/TiO2 composites were studied. For this purpose two different sets of PS films with thicknesses of 5 and 20 mu m were prepared from pyrene-(P-) labeled PS particles and ...
