“…Plasticizers also contribute to better nanofiller dispersion in the matrix, giving amazing mechanical properties. Thermoplastic PLA, produced by cornstarch fermentation, is a most frequently used biopolymer for the production of bioplastic blended with organically altered silicates [22,23]. The addition of titanate as a nanofiller to PLA bioplastics results in improvement in biodegradation, comparable to TiO 2 [24].…”

This chapter presents a broad overview of the current advancements in bioplastics and bioinspired nanocomposites with nanoscale reinforcements that are being applied for a broad range of applications, that is, biomedical, electronics, durable goods and packaging materials. The production of nanocomposites by completely and/or partially renewable and biodegradable materials has helped in a range of different applications. Several drawbacks of conventional materials such as hydrophilicity, low-heat deflection, poor conductivity, and barrier properties can be efficiently overcome using biohybrid nanomaterials. Nano-reinforcements in composite materials deliver remarkably improved properties such as decrease in hydrophilicity and increase in mechanical properties as compared with neat biopolymer, which fails to exhibit these properties on its own. This approach can be used for other natural polymers to induce desired functionalities. This chapter covers the recent trends in nano-functional materials, renewable materials that are being applied for the production of nanobiocomposites and their applications especially in biomedical and healthcare sectors, which are discussed in detail. This emerging concept will definitely enhance the scope of nanohybrid materials for sustainable products development with improved properties than previously applied synthetic polymer-based or natural polymer-based materials.

“…However, high amylopectin starches result in more stable systems, with starch dispersed in water, and produce softer gels and weaker films. 31 The retrogradation occurs when, due to the approximation of amylose chains, the macromolecular components, previously disordered, are organized, forming crystalline regions. 32 It causes changes in film properties and is a phenomenon that occurs when starch is cooled down.…”

Starch–gelatin film as an alternative to the use of plastics in agriculture: a review

et al. 2019

BACKGROUND The technological advances in agriculture, driven by the increased demand for food attributed to population growth, have led to the search for technologies that allow greater control over the variables that interfere in crop yield. Several techniques stand out for optimizing yield capacity, including cultivation in a protected environment, mulching and low tunneling. To expand the use of these techniques, synthetic petroleum‐based polymers are employed due to their low cost, easy processing, and lightness. However, they take a long time to degrade, and, since they are discarded at the end of each cycle of cultivation, end up accumulating in the environment causing irreversible damage. RESULTS The use of biodegradable films, made of starch and/or a protein source such as gelatin, has been studied as a promising alternative. Both stand out because of their film‐forming ability, and because they come from abundant sources and are biodegradable. CONCLUSION This study aimed to review the current findings on starch and gelatin films that can be used as alternatives to conventional plastics in agricultural crops. © 2019 Society of Chemical Industry

“…Other the hand, biodegradable aliphatic polyester (such as polylactic acid (PLA) and polycaprolactone (PCL)) is hydrophobic, with good mechanical properties but great expense. Consequently, blending of starch and these polyesters to overcome their disadvantages to obtain improved performance has become a hotspot in research . For instance, Komur et al .…”

Preparation and Properties of Compatible Starch‐PCL Composites: Effects of the NCO Functionality in Compatibilizer

et al. 2020

As is well known, poor interfacial interactions between hydrophilic corn starch (CS) and hydrophobic thermoplastic matrices have been an obstacle in application of the quality biomass material like CS. The addition of compatibilizers is an effective method to improve the interface interaction. In this work, a special interficial structure using polyurethane crosslinked layer as compatible interface is designed and compatibilizers with different NCO functionality are also applied. The purpose of this work is to investigate the effects of compatibilizers with different NCO functionality (f, f = 0, 1, 2, 3) on the compatibility of corn starch‐polycaprolactone (CS‐PCL) composites. Subsequently, various CS‐PCL composites are prepared using compatiblizers with different NCO functionality (f = 0, 1, 2, 3) via melting process. The structural analysis, mechanical properties, and water absorption capability as well as the thermal stability of the composites reveal that the properties of the composites are only enhanced significantly when the NCO functionality is no less than 2. In short, when f ≥ 2, a crosslinked layer could be formed at the interface of the composite to afford a compatible CS‐PCL composite.
