“…Other works have focused on modifying starch through the addition of fillers to improve the overall properties of starch foams. The used fillers include fish scale powder [399], coconut residue fibre [400], cellulose fibres [394], cellulose nanofibers [401], cellulose microfibres [402], sesame cake [403], sugarcane bagasse fibres [404,405], grape stalks [406,407], peanut skin [408], barley straw fibres [163], sisal fibres [409], silica or nanosilica particles [410,411], aluminium hydroxide [412], calcified green macroalga [413], egg shell and shrimp shell [414], natural oat fibres [415], sunflower oil press cake [416], water hyacinth fibres [417], Khlum fibres [418], and cotton fibres [419]. Kaewtatip et al [414] reported starch/egg shell composite foams prepared by a baking process with lower density (0.2056 g/cm 3 ), a narrower pore size distribution, and higher impact strength compared to neat starch foams and attributed the improvement of the foam properties to the steady growth of steam bubbles due to the nucleating effect of the egg shell which helped to prevent the bubbles from collapsing during the baking process.…”

The last few decades have witnessed significant advances in the development of polymeric-based foam materials. These materials find several practical applications in our daily lives due to their characteristic properties such as low density, thermal insulation, and porosity, which are important in packaging, in building construction, and in biomedical applications, respectively. The first foams with practical applications used polymeric materials of petrochemical origin. However, due to growing environmental concerns, considerable efforts have been made to replace some of these materials with biodegradable polymers. Foam processing has evolved greatly in recent years due to improvements in existing techniques, such as the use of supercritical fluids in extrusion foaming and foam injection moulding, as well as the advent or adaptation of existing techniques to produce foams, as in the case of the combination between additive manufacturing and foam technology. The use of supercritical CO2 is especially advantageous in the production of porous structures for biomedical applications, as CO2 is chemically inert and non-toxic; in addition, it allows for an easy tailoring of the pore structure through processing conditions. Biodegradable polymeric materials, despite their enormous advantages over petroleum-based materials, present some difficulties regarding their potential use in foaming, such as poor melt strength, slow crystallization rate, poor processability, low service temperature, low toughness, and high brittleness, which limits their field of application. Several strategies were developed to improve the melt strength, including the change in monomer composition and the use of chemical modifiers and chain extenders to extend the chain length or create a branched molecular structure, to increase the molecular weight and the viscosity of the polymer. The use of additives or fillers is also commonly used, as fillers can improve crystallization kinetics by acting as crystal-nucleating agents. Alternatively, biodegradable polymers can be blended with other biodegradable polymers to combine certain properties and to counteract certain limitations. This work therefore aims to provide the latest advances regarding the foaming of biodegradable polymers. It covers the main foaming techniques and their advances and reviews the uses of biodegradable polymers in foaming, focusing on the chemical changes of polymers that improve their foaming ability. Finally, the challenges as well as the main opportunities presented reinforce the market potential of the biodegradable polymer foam materials.

“…On the other hand, starch-based films have shown poor thermal stability, low mechanical strength, and decomposition temperature [6]. Cao et al stated that mixing starch with chitosan overcomes these disadvantages and improves some properties of starch such as easy film forming and antibacterial properties [7].…”

As known, composite films containing different metal ions provide improvement in the properties of drug release systems. In this study, it was aimed to prepare composite films containing different metal ions for DOX release, and the effect of metal ions on drug release, swelling, and thermal properties were investigated. The structural characterization of the composite films was carried out using FT-IR, SEM, and TG analysis techniques. SEM images showed that the metal-free film was composed of a homogeneous structure while the calcium composite films consisted of a non-homogenous surface. Also, thermal analysis results showed that the thermal stability increased with the addition of metal ions to the composite film matrix. The swelling and drug-release behavior of the composite films were also studied, and metal ions-containing films exhibited a higher swelling performance and drug-release behavior than the metal-free composite.

In order to actively promote green production and address these concerns, there is an urgent need for new packaging materials to replace traditional plastic products. Starch−based packaging materials, composed of starch, fiber, and plasticizers, offer a degradable and environmentally friendly alternative. However, there are challenges related to the high crystallinity and poor compatibility between thermoplastic starch and fibers, resulting in decreased mechanical properties. To address these challenges, a novel approach combining plasticizer optimization and response surface method (RSM) optimization has been proposed to enhance the mechanical properties of starch−based packaging materials. This method leverages the advantages of composite plasticizers and process parameters. Scanning electron microscopy and X-ray crystallography results demonstrate that the composite plasticizer effectively disrupts the hydrogen bonding and granule morphology of starch, leading to a significant reduction in crystallinity. Fourier transform infrared spectroscopy results show that an addition of glycerol and D−fructose to the starch can form new hydrogen bonds between them, resulting in an enhanced plasticizing effect. The optimal process parameters are determined using the RSM, resulting in a forming temperature of 198 °C, a forming time of 5.4 min, and an AC content of 0.84 g. Compared with the non−optimized values, the tensile strength increases by 12.2% and the rebound rate increases by 8.1%.
