본문내용
* Polymer layered silicate nanocomposites filled with inorganic clay minerals dispersed as nanoplatelets posses attractive enhancement in certain properties like optical, thermal, rheological and barrier properties
* Improvement in properties is achieved even at lower loading of clay (2 to 5 wt %) leading to light weight nanocomposite materials
* Water dispersible nanocomposites has become a subject of research in recent era due to ease of processing and their applications in water-borne adhesives, paints and coating formulations
* In the present work, water dispersible polymer nanocomposites based on polyvinyl alcohol have been prepared and characterized
