PHYSICOCHEMICAL, MECHANICAL & FILM FORMING STUDIES OF NOVEL BIOMATERIALAbstract
Gum Dammar is a natural resinous material of plant Shorea javanica, family–Dipterocarpaceae. In the present investigation Dammar gum (DG) and alcohol soluble fraction of Dammar gum (DA) are evaluated for their physicochemical, mechanical and film forming characteristics. Films were produced by casting/solvent evaporation method from plasticizer free and plasticizer containing solutions. Films prepared from different formulations were studied for their mechanical (tensile strength, percent elongation and Young’s modulus), water vapor transmission and moisture absorption characteristics. Unplasticized DG, DA films were brittle and posed the problem of breaking during handling. Hydrophobic plasticizers, dibutyl phthalate (DBP), improved the mechanical properties of free films with plasticizer showing significant effects on film elongation. Thus present study proposes DG and DA as excellent film formers.
