Abstract:In this study, low density polyethylene (LDPE) was melt-blended with starch using twin screw extruder to form biodegradable polymer blends. The LDPE/starch blend films used in food packing were obtained by hot pressing of the granules produced by extrusion process. The starch content was varied from 0 to 40 wt% of LDPE. To provide fine starch dispersion, glycerol and zinc stearate were used as plasticizer and compatibilizer, respectively. The effect of starch content on the properties of LDPE film was investigated. A good dispersion was achieved for low starch contents (10 and 20 wt%), but agglomeration of the starch particles occurred in the presence of high amounts of starch (>20 wt%). The addition of starch to LDPE reduced the tensile strength, elongation at break, crystallinity, and water resistance of LDPE. This decline in the LDPE properties was dramatic when the starch content was increased to 30 wt% in the blend. In addition, silver nanoparticles as antibacterial agent were incorporated to the biodegradable LDPE blends where LDPE/starch weight ratio of 60/40. The effects of these nanoparticles on morphological, mechanical, thermal and water resistance properties of the LDPE/starch biodegradable blends were investigated. It was observed that the incorporation of nanoparticles to the LDPE/starch blend was completely changed the morphology of the film, and accordingly, the mechanical, thermal, and water resistance properties were varied depending on the silver nanoparticle content in LDPE/starch blend film. Moreover, antibacterial activities of the nanocomposite films against gram-negative bacteria (E. coli) and grampositive bacteria (S. aureus) were determined by measuring the inhibition zone around each film. However, the nanocomposite films did not show any antibacterial activities in the presence of silver nanoparticles as an antibacterial agent.

“…Indeed during the last few years, natural cellulosic fibers have received much more attention than ever before from the research community all over the world. The 'green' composites prepared using these natural fibers demonstrate good mechanical properties such as tensile, compressive and flexural strength and may be used for various applications [4][5][6][7]. Biofibers are now being considered as serious alternative to synthetic fibers for use in various fields.…”

Natural cellulosic fibers are one of the smartest materials for use as reinforcement in polymers possessing a number of applications. Keeping in mind the immense advantages of the natural fibers, in present work synthesis of natural cellulosic fibers reinforced polymer composites through compression molding technique have been reported. Scanning Electron microscopy (SEM), Thermo gravimetric/Differential thermal/Derivative Thermogravimetry (TGA/DTA/DTG), absorption in different solvents, moisture absorbance, water uptake and chemical resistance measurements were used as characterization techniques for evaluating the different behaviour of cellulosic natural fibers reinforced polymer composites. Effect of fiber loading on mechanical properties like tensile strength, flexural strength, compressive strength and wear resistances has also been determined. Reinforcing of the polymer matrix with natural fibers was done in the form of short fiber. Present work indicates that green composites can be successfully fabricated with useful mechanical properties. These composites may be used in secondary structural applications in automotive, housing etc.

“…A hump like shape has been observed at around 3600-3000 cm À1 region of both LDPE=TD and LDPE= TD M composites due to the hydrogen bonding, which is intensified with the presence of tyre dust. The functional group peak observed is due to the formation of more hydrogen bond, which supports the molecule-molecule interaction between two polar groups [17] . The peak observed in the region 1680-1630 cm À1 of LDPE=TD M composites shows C = O stretches due to anhydride group present in LDPE backbone as a pendant chain.…”

The effect of phthalic anhydride as a new coupling agent on the properties of low density polyethylene/tyre dust (LDPE/TD) composites was studied. LDPE/TD composites with different tyre dust filler loading and the addition of phthalic anhydride were prepared with Z-blade mixer. The result indicated that LDPE/TD M composites with phthalic anhydride show higher tensile strength, modulus of elasticity, thermal stability and swelling resistance than LDPE/ TD composites. The interfacial adhesion between LDPE and TD was improved with the addition of phthalic anhydride as evidenced by the morphological study.
