Abstract

Steady state fluorescence (SSF) and photon transmission (PT) techniques were used for studying film formation from TiO₂ and Al₂O₃ covered polystyrene (PS) latex particles. These films were annealed at elevated temperatures in 10 min time intervals above glass transition (T_g) temperature of polystyrene. Fluorescence emission, I_p and transmitted photon, I_tr intensities were measured after each annealing step to monitor the stages of film formation. Films present dramatic increase in both I_tr and I_p above the certain onset temperature called minimum film forming temperature, T₀. Dissolution of annealed PS film, with high TiO₂ content presented a nice, ordered nano-sized ceramic structure, which may predict the construction of nano-layer photonic crystals. It was observed that latex particles are encapsulated above a critical Al₂O₃ content of 33 wt% which corresponds to the critical occupation probability of p_c=0.33 at which the film obey the site-percolation model with a critical exponent of 0.45.
