Here hydroxypropyl methylcellulose(HPMC) films prepared, and incorporated with additives materials (i.e. stearic acid (SA), aluminum nanoparticles (Al) and molybdenum disulphide (MoS2). which enhance its mechanical properties and water vapor permeability resistant. For HPMC 606 added with stearic acid, the maximum rise in tensile strength was at 0.15 wt.% to 34 % of the pure HPMC 606, similarly for Al nanoparticles at 0.25 wt.% increased to 24 % and for molybdenum disulphide at 1 wt.% increased to 33 %. Further increased in additives concentration level, resulted in drops of mechanical properties of the respective films. When additives concentration increased above these values, forms long grains boundaries inside the matrix and it leads to increase brittle behavior of the films. There was decreased in the water vapor permeability’s of the films added with incorporative materials.
Similarly, there was increased in mechanical properties and decreased in water vapor permeability for the HPMC 645 and HPMC 615, when incorporative materials used. Incorporation of additives into the HPMC films were capable of improving the tensile strength and Young’s modulus of HPMC, but it decreases after certain level because further addition of additives causes formation of granules inside the matrix and it leads to increase films brittleness. Which results in decreased percent elongation of the HPMC films. Among these three HPMC types, HPMC 615 shows good mechanical properties as compare to other two HPMC. Thus HPMC 615 with additives have excellent mechanical properties. This type of hybrid films with superior properties is expected to be useful in eco-friendly food packaging applications, pharmaceutical companies and in various industrial used.
