“…By adding nZnO particles to the solution, the free water molecules content decreases, which reduces flexibility and increases the strength of the resulting films. The reported observations are in good agreement with open literature [12,17,25]. Since the average thicknesses of the different samples used in calculating the UTS were relatively close, the effect of sample thickness on the dressings' UTS is negligible in this study.…”

“…However, its applications are limited by starch's poor mechanical properties, high brittleness, and reduced water sensitivity. Mainly, adding up other macromolecular compounds into starch can improve the physicochemical properties of the films [12]. Among them, a biodegradable and water-soluble synthetic polymer, polyvinyl alcohol (PVA), is frequently mixed with starch to enhance its properties.…”

Given recent worldwide environmental concerns, biodegradability, antibacterial activity, and healing properties around the wound area are vital features that should be taken into consideration while preparing biomedical materials such as wound dressings. Some of the available wound dressings present some major disadvantages. For example, low water vapor transmission rate (WVTR), inadequate exudates absorption, and the complex and high environmental cost of the disposal/recycling processes represent such drawbacks. In this paper, starch/polyvinyl alcohol (PVA) material with inserted nano-sized zinc-oxide particles (nZnO) (average size ≤ 100 nm) was made and altered using citric acid (CA). Both ensure an efficient antibacterial environment for wound-dressing materials. The film properties were assessed by UV–Vis spectrometry and were validated against the UV light transmission percentage of the starch/ polyvinyl alcohol (PVA)/ zinc-oxide nanoparticles (nZnO) composites. Analyses were conducted using X-ray Spectroscopy (EDX) and scanning electron microscopy (SEM) to investigate the structure and surface morphology of the materials. Moreover, to validate an ideal moisture content around the wound area, which is necessary for an optimum wound-healing process, the water vapor transmission rate of the film was measured. The new starch-based materials exhibited suitable physical and chemical properties, including solubility, gel fraction, fluid absorption, biodegradability, surface morphology (scanning electron microscopy imaging), and mechanical properties. Additionally, the pH level of the starch-based/nZnO film was measured to study the prospect of bacterial growth on this wound-dressing material. Furthermore, the in vitro antibacterial activity demonstrated that the dressings material effectively inhibited the growth and penetration of bacteria (Escherichia coli, Staphylococcus aureus).

“…The global market of start-based bioplastics was valued at $424 million in 2016, and is projected to reach the value of $561 million by 2023, registering a 3.7% increase in CAGR (Roy, 2017). As one of packaging solutions with the highest potential, starch-based bioplastics have been improved and applied in different ways including (1) blended with other compostable polymers such as PLA, PBS and PHAs to reduce the production cost; (2) blended with natural nanoparticles for reinforced nanocomposite to enhance mechanical, thermal and water resistance properties (Anugrahwidya et al, 2021;Hong et al, 2021;Sun et al, 2014;Zhang et al, 2014). Potential future applications could be loose fill packaging and injection molded products such as take-away food containers (Babu et al, 2013).…”

“…Bioplastics are plastics that can be degraded naturally because they are composed of natural polymers such as starch, cellulose, and proteins or lipids [9]. However, starch is the main ingredient in the manufacture of bioplastics because starch has biodegradability, easier to process, and is economical [10]. In addition, in agrarian countries such as Indonesia, the development of starch-based bioplastics is very appropriate because starch is easily obtained from most plants in Indonesia [11].…”

The increase in plastic causes environmental problems. Indonesia ranks second with 5.4 million tons/year. Plastic waste cannot be degraded, so it is necessary to replace plastics with biopolymers as bioplastics. Starch-based bioplastics have high biodegradability, one of which is from durian seeds. Durian seeds have a fairly high starch content of 76.65%. Optimization of the mechanical properties of bioplastics in the form of extension needs to be done. This study aims to obtain the gelatinase temperature process conditions, glycerol and chitosan compositions that produce optimum bioplastic elongation. The optimization method uses a Response Surface Methodology based on Central Composite Design. The experiments were gelatinization temperature (80, 85, and 90°C), glycerol concentration (1.5; 2.5; and 3.5 g), and chitosan concentration (2, 3, and 4 g). The results of the study were the optimum conditions at a gelatinization temperature of 80°C, a concentration of 2 g of chitosan, and 3.5 g of glycerol with an elongation value of 26.67%. Biodegradation test for 7 days resulted in a mass reduction of 90.02% according to European standard EN: 13432.2000.
