In this work, polypropylene/thermoplastic starch (PP/TPS) with and without halloysite nanotubes (HNTs) was prepared via melt mixing in order to obtain environmentally friendly plastics. PP-grafted maleic anhydride (PP-g-MA) was used to improve the compatibility among the highly incompatible polymers. The mechanical characterization showed a reduction in the tensile properties of the polymer when TPS increased; however, HNT successfully compensated for some of the observed losses. The results from the thermogravimetric analysis (TGA) indicated that HNT is an efficient reinforcement for the thermal stability improvement. TPS caused an increase in the storage modulus (G 0 ) and the complex viscosity (h*) which marks a change in the viscoelastic properties of the system. The scanning electron microscope (SEM) images showed the effective plasticization of starch and better dispersion of TPS in the presence of HNT. Some samples were also buried in the soil to measure their sustainability after their lifetime lapse. The results indicated that TPS improves the biodegradability of the PP/TPS system. PP considerably lowered the moisture uptake of TPS; nevertheless, HNT caused a slight increase in the moisture absorption.

“…Among natural biopolymers, starch is a carbohydrate storage material accumulated by green plants in the form of granules; it has been considered as one of the most promising candidates because of its low specific gravity, low‐cost, biodegradable nature, and renewability. Starch can promote the biodegradability of a nonbiodegradable plastic when blended . Recent studies have focused on starch‐based biodegradable blends for reducing environmental pollution; these blends get consumed by microorganisms and leave behind a matrix with higher surface area.…”

Starch was treated with three kinds of compatibilizers (coupling agents or modifying agents), KH-550, KH-570, and glycerin monostearate. Blends of polypropylene (PP) and treated starch were prepared by a twin-screw extruder. The effects of the starch before and after treatments and the kinds and contents of the compatibilizers on the mechanical and thermal properties of the PP/ starch blends were investigated in this study. We found that the mechanical properties (tensile strength, impact strength, and elongation at break) of the blends were obviously improved with increasing content of different kinds of compatibilizers. Meanwhile, the most significant improvement in the mechanical properties was obtained in the samples containing just a 1 wt % loading of compatibilizers, and KH-570 had the best improved effects among the different kinds of compatibilizers. The results of thermogravimetric analysis demonstrate that to some extent, the thermal stability of the PP/starch blends was improved after the addition of compatibilizers. Scanning electron microscopy showed that the dispersion of starch in the PP matrix and adhesion between the starch and PP matrix were obviously improved after the addition of compatibilizers. KH-570 not only had the best improved effects among the coupling agents but also still acted as a similar plasticizer.

In this study the biodegradability of Soy protein Concentrate (SPC) crosslinked with Corn starch (CS) and Cloisite 30B (C30B) has been discussed threadbare. The nanocomposites were prepared by employing the solution casting method. The physical and chemical properties of nanocomposites SPC-CS/C30B were investigated using XRD, FTIR, SEM, TGA and tensile strength. The biodegradationproperties of samples were measured by micro-organic culture testing, enzymatic absorbance in water, soil burial and compost testing in both laboratory and field conditions. SPC-CS/C30B nanocomposites exhibited favourable physical properties. Additionally it was observed that when the percentage of C30B was increased up to 4% with SPC/CS, the tensile strength was also increased up to 45.67%. The morphology study of SPC-CS/C30B was found exfoliated form with porous structure.
