Preparation and characterization of polyvinyl alcohol–starch composites reinforced with pulp

Herein, we have investigated the reinforcing potential of starch and cellulose pulp in a matrix of polyvinyl alcohol (PVA). Polyvinyl alcohol, starch, and pulp fibers having different compositions were constructed in order to achieve better reinforced composite films. Various techniques were utilized for extract the physical, mechanical as well as thermal properties. The magnitudes of tensile strength were reduced with rising of starch content in PVA. Tensile strength values of (PVA + starch) mixtures were enhanced with the enhancement of pulp fibers content. The properties of bulk density and water absorption revealed the significant impact of starch and pulp fibers. The obtained result of thermal stability of PVA was superior which was reduced by addition of starch content; therefore, regained with the insertion of pulp fibers content in PVA–starch matrix.
