Effect of Polystrene Latexes on the film formation of Polymer Composite Films by Infrared Heating

Öz

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.

Kızılötesi Isıtma ile Polistiren Latekslerin Polimer Kompozit Filmlerindeki Film Oluşumuna Etkisi

Öz

Bu çalışma, polistiren (PS) -poliakrilamid (PAAm) ve polistiren (PS) -Na Alginat (Alg) kompozitlerinden film oluşumunun UV-Visible tekniği kullanılarak incelendiği spektroskopik bir teknik sunmaktadır. Tüm numuneler, (PS) -poliakrilamid (PAAm) ve polistiren (PS) -Na Alginat (Alg) filmlerinin farklı bileşimleriyle bir cam substrat üzerine damlatma yöntemiyle oda sıcaklığında hazırlandı. Kızılötesi ısıtma ile tavlanan filmlerin boşluk kapanması ve interdifüzyon aşamaları için karşılık gelen aktivasyon enerjileri hesaplandı. , kızılötesi ısıtma ile tavlanan Polistiren (PS)-Na Alginat (Alg) kompozit filmler için boşluk kapatma işlemleri için hesaplanan enerjilerin polistiren (PS)-poli akrilamid (PAAm) kompozit filmlerden daha küçük olduğu bulundu.
