Abstract
This work presents a spectroscopic technique that film formation from polystyrene (PS)-polyacrylamide (PAAm) and polystyrene (PS)/Na-Alginate (Alg) composites was investigated using by UV-Visible technique. All samples were prepared at room temperature by casting methode on a glass substrate with different compositions of (PS)/polyacrylamide (PAAm) and polystyrene (PS)/Na- Alginate (Alg) films. Corresponding activation energies for the void closure and the interdiffusion stages were calculated of the films annealed by infrared heating. It was found that the calculated energies for the void closure processes smaller for the polystyrene (PS)/Na-Alginate (Alg) composite films than that of polystyrene (PS)/polyacrylamide (PAAm) composite films by infrared heating.
