In the field of hybrid natural fiber polymer composites, there has been a recent surge in research and innovation for structural applications. To expand the strengths and applications of this category of materials, significant effort was put into improving their mechanical properties. Hybridization is a designed technique for fiber-reinforced composite materials that involves combining two or more fibers of different groups within a single matrix to manipulate the desired properties. They may be made from a mix of natural and synthetic fibers, synthetic and synthetic fibers, or natural fiber and carbonaceous materials. Owing to their diverse properties, hybrid natural fiber composite materials are manufactured from a variety of materials, including rubber, elastomer, metal, ceramics, glasses, and plants, which come in composite, sandwich laminate, lattice, and segmented shapes. Hybrid composites have a wide range of uses, including in aerospace interiors, naval, civil building, industrial, and sporting goods. This study intends to provide a summary of the factors that contribute to natural fiber-reinforced polymer composites’ mechanical and structural failure as well as overview the details and developments that have been achieved with the composites.

“…The general classification of bio-based polymers is depicted in Figure 6 . They can be broadly classified into three categories, which are (1) polymers directly extracted from biomass sources, (2) polymers chemically synthesized from bio-derived monomers, and (3) polymers produced directly by microorganisms [ 83 ]. Polymers such as poly(lactic acid) (PLA), starch, cellulose, and chitosan are gaining more favor in the antimicrobial packaging.…”

The development of antimicrobial packaging has been growing rapidly due to an increase in awareness and demands for sustainable active packaging that could preserve the quality and prolong the shelf life of foods and products. The addition of highly efficient antibacterial nanoparticles, antifungals, and antioxidants to biodegradable and environmentally friendly green polymers has become a significant advancement trend for the packaging evolution. Impregnation of antimicrobial agents into the packaging film is essential for impeding or destroying the pathogenic microorganisms causing food illness and deterioration. Higher safety and quality as well as an extended shelf life of sustainable active packaging desired by the industry are further enhanced by applying the different types of antimicrobial packaging systems. Antimicrobial packaging not only can offer a wide range of advantages, but also preserves the environment through usage of renewable and biodegradable polymers instead of common synthetic polymers, thus reducing plastic pollution generated by humankind. This review intended to provide a summary of current trends and applications of antimicrobial, biodegradable films in the packaging industry as well as the innovation of nanotechnology to increase efficiency of novel, bio-based packaging systems.

Nanocrystalline Cellulose from Kapok Fiber (Ceiba pentandra) and its Reinforcement Effect on Alginate Hydrogel Bead

et al. 2021

Kapok fiber (Ceiba pentandra) is a potential source of cellulose, but its utilization is still minimal. This study aims to isolate nanocrystalline cellulose (NCC) from kapok fibers using acid hydrolysis at various times and characterize its properties as reinforcement for alginate-nanocrystalline cellulose (Alg-NCC) hydrogel beads. NCCs are characterized using various techniques, and hydrogel beads are characterized by syneresis and strength (TPA). Variations in hydrolysis time cause changes in functional groups, decrease length and diameter, increase degree of crystallinity, and thermal stability. Nanocrystalline cellulose isolation from BKF by chemical hydrolysis is better done at 60% sulfuric acid concentration, for 50 min to produce a yield of 38.92%, L/d aspect ratio ranges from 8.53 to 12.23, degree of crystallinity 71.00%, and thermal stability with maximum degradation temperature 298.69°C. The incorporation of NCC on the Alg hydrogel beads leads to increase hardness 67.70% and decrease syneresis 4.14%. Thus, NCC can be used as a reinforcement agent because it has been shown to improve the physical, mechanical, and thermal properties of Alg-NCC hydrogel beads. Alg-NCC hydrogel beads have the potential to be widely applied in various fields.
