“…Numerous studies have been conducted in search of sustainable and ecological alternatives to deal with the excessive production of plastic derived from fossil hydrocarbons [ 6 , 7 , 8 , 9 , 10 ]. The main objective is to find low-cost and biodegradable materials with good mechanical properties and high quality [ 11 ]. One of the alternatives is biopolymers manufactured from biomass or organic waste, which come from natural sources because they are abundantly available and inexpensive.…”

The development of bio-based materials has been a consequence of the environmental awareness generated over time. The versatility of native starch is a promising starting point for manufacturing environmentally friendly materials. This work aims to compile information on the advancements in research on thermoplastic starch (TPS) nanocomposites after the addition of mainly these four nanofillers: natural montmorillonite (MMT), organically modified montmorillonite (O-MMT), cellulose nanocrystals (CNC), and cellulose nanofibers (CNF). The analyzed properties of nanocomposites were mechanical, barrier, optical, and degradability. The most important results were that as the nanofiller increases, the TPS modulus and strength increase; however, the elongation decreases. Furthermore, the barrier properties indicate that that the incorporation of nanofillers confers superior hydrophobicity. However, the optical properties (transparency and luminosity) are mostly reduced, and the color variation is more evident with the addition of these fillers. The biodegradability rate increases with these nanocompounds, as demonstrated by the study of the method of burial in the soil. The results of this compilation show that the compatibility, proper dispersion, and distribution of nanofiller through the TPS matrix are critical factors in overcoming the limitations of starch when extending the applications of these biomaterials. TPS nanocomposites are materials with great potential for improvement. Exploring new sources of starch and natural nano-reinforcement could lead to a genuinely eco-friendly material that can replace traditional polymers in applications such as packaging.

“…[14] This drawback can be minimized by using an appropriate synthetic polymer matrix along with TPS to prepare a hybrid composite. [15][16][17][18] The development of a new type of hybrid polymer matrix by mixing both synthetic and natural polymer may lead to open a new avenue and thus widen the area of applications and brings a new dimension to the world of polymer composites.…”

In this study, we prepared a green heat stabilizer tannic acid–calcium oxide (TA–CaO) adduct in a green method and its efficacy was studied in a bio‐based polyvinyl chloride‐thermoplastic starch polymer matrix. The composite was prepared in a green pathway by melt mixing. CaO in the prepared complex also acted as a reinforcing filler in the composite. The addition of TA–CaO adduct in place of lead carbonate improved all the physical and chemical properties of the composite. The tensile strength and flexural strength improved to 102% and 127%, respectively, in comparison with similar percentage of lead carbonate and TA–CaO adduct. The composite with 15 phr loading of TA–CaO showed improved properties compared with other TA–CaO loaded composites.

“…Abundant studies have revealed that the incorporation of starch to low density polyethylene (LDPE) follows the common trend for filler effects on the polymer properties. Deterioration of mechanical properties of this blend is due to incompatibility between two phases (Chaoui et al, 2020;Hammache et al, 2020;Waryat et al, 2013). Several efforts have been done to enhance the compatibility and adhesion between two phases including treatment either starch or polyethylene.…”

Purpose This study aims to develop a biodegradable linear low-density polyethylene (LLDPE)/starch blends with improved mechanical and flow characteristics and evaluate the probability of using essential oils such as Moringa oleifira and castor oils as green plasticizers and compatibilizers to avoid using harmful chemicals. Design/methodology/approach Corn starch was blended with LLDPE through the melt blending technique. The corn starch content was varied from 5 to 40 phr in LLDPE. To enhance poor mechanical characteristic of the LLDPE/starch, essential oils such as M. oleifira and castor oils were incorporated into the composites with different concentrations starting from 1 to 7 phr. The essential oils’ effect on mechanical, flow character, thermal stability and electrical properties of the LLDPE/starch was also investigated. The morphology of LLDPE/starch containing essential oils was also investigated by scanning electron microscope (SEM). Findings The results revealed that increasing the corn starch content had an adverse effect on mechanical and flow characteristics of the composites, whereas incorporation of essential oils had increased the flow and mechanical characteristics of the composites. Also, dielectric measurements revealed that permittivity and dielectric loss increased by increasing oil content. Moreover, the values of the blends containing castor oil are higher compared to that containing M. oleifira. The SEM micrographs illustrated that the presence of essential oils in LLDPE/starch enhanced the distribution and the homogeneity of the composites, and the particle size of starch granules became smaller in LLDPE matrix. Originality/value This study aims to introduce green plasticizer and compatibilizer to avoid using harmful chemicals in packaging industry.
