Fluorescence study of effect of particle size in PS latex/Al 2 O 3 nanocomposite films

Abstract

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; LgPS: 382 nm) templates with various layers of Al₂O₃ by dip coating method. The film formation behaviours of composites were studied by annealing them at a temperature range of 100–250°C and monitoring the scattered (I_sc), fluorescence (I_P) and transmitted (I_tr) light intensities after each annealing step. The results indicate that LgPS/Al₂O₃ films underwent complete film formation independent of Al₂O₃ content while no film formation occurred above a certain Al₂O₃ content for SmPS/Al₂O₃. Extraction of PS produced ordered porous structures for high Al₂O₃ content in both series. Scanning electron microscopy images showed that the pore size and porosity could be easily tailored by varying PS particle size and Al₂O₃ content.
