Characterizations of PVA Composites Based on Recycled Ultrafine Cotton and Wool Powders

Ahmed G Hassabo,Mohamed Salama and Crisan Popescu


Different percentages of cotton and wool micro particles (average size 20-80 m) were added to two different molecular weight of polyvinyl alcohol (22000& 145000 Da) during preparation of film (30 m) by casting technique. Morphological surface study of a prepared composite film was established by Scanning Electron microscopy (SEM). Many characterizations were investigated, thermally dynamics properties investigated by Differential Scanning Calorimetry (DSC), Thermal Gravimetric Analysis (TGA) and Mechanical properties. All the result support that the prepared composites film have a good distribution of the particles through the film and improve the thermal and mechanical properties of the PVA film. The ability of these composites to absorb water (moisture content) and formaldehyde from the environmental surrounding were examined and evaluated.
