The use of agents in the form of nanochitosan to develop active bioplastics offers a new way to modify the transport properties and release of active compounds while increasing the mechanical resistance and compatibility between polymers. This study aims to study the effect of mixing two polymers in the form of polylactic acid (PLA) and polycaprolactone (PCL) as a matrix and 10% (w/v) filler. The matrix for bioplastic film-forming was prepared by mixing 8 g PLA and 2 g PCL. The internal film and surface microstructures were characterized by scanning electron microscopy (SEM) and interactions between the particles using FT-IR. Mechanical physical properties were reviewed using ASTM D638. The results show that amount of filler composition promotes a significant change in the microstructure of the film and is associated with to improve properties. The amount of nanochitosan (0.9 g) and catechin (0.1) was homogeneously distributed. As a consequence. However, when the filler composition is varied in other quantities, the tensile strength will fluctuate.

“…Extracellular polysaccharides or cell wall-associated proteins identified in the biofilm matrix have the ability to stimulate an immune response that protects against S. aureus infection. Resistance to S. aureus can be acquired by active or passive vaccination with surface polysaccharides [41]. In contrast to S. aureus, E. coli bacteria live in the digestive system as part of the microbiota and may be a dangerous adversary.…”

This study aims to produce and investigate the potential of biodegradable Polylactic Acid (PLA)-based composites mixed with chitosan and Turmeric Essential Oil (TEO) as an anti-microbial biomaterial. PLA has good barrier properties for moisture, so it is suitable for use as a raw material for making packaging and is included in the GRAS (Generally Recognized As Safe). Chitosan is a non-toxic and antibacterial cationic polysaccharide that needs to be improved in its ability to fight microbes. TEO must be added to increase antibacterial properties due to a large number of hydroxyl (-OH) and carbonyl functional groups. The samples were prepared in three different variations: 2 g of chitosan, 0 mL TEO and 0 mL glycerol (Biofilm 1), 3 g of chitosan, 0.3 mL TEO and 0.5 mL of glycerol (Biofilm 2), and 4 g of chitosan, 0.3 of TEO and 0.5 mL of glycerol (Biofilm 3). The final product was characterized by its functional group through Fourier transform infrared (FTIR); the functional groups contained by the addition of TEO are C-H, C=O, O-H, and N-H with the extraction method, and as indicated by the emergence of a wide band at 3503 cm−1, turmeric essential oil interacts with the polymer matrix by creating intermolecular hydrogen bonds between their terminal hydroxyl group and the carbonyl groups of the ester moieties of both PLA and Chitosan. Thermogravimetric analysis (TGA) of PLA as biofilms, the maximum temperature of a biofilm was observed at 315.74 °C in the variation of 4 g chitosan, 0.3 mL TEO, and 0.5 mL glycerol (Biofilm 3). Morphological conditions analyzed under scanning electron microscopy (SEM) showed that the addition of TEO inside the chitosan interlayer bound chitosan molecules to produce solid particles. Chitosan and TEO showed increased anti-bacterial activity in the anti-microbial test. Furthermore, after 12 days of exposure to open areas, the biofilms generated were able to resist S. aureus and E. coli bacteria.

“…[29] Several papers have already been published on the manufacturing and mechanical testing of natural fiberreinforced epoxy composite, including bamboo fiber-reinforced epoxy. [30][31][32][33][34][35][36] Most of these studies focused on tailoring the composite material's mechanical properties; however, to use the bamboo fiber-reinforced epoxy composite in load-bearing applications, characterization of the tribological behavior of the composite is needed.…”

Bamboo fiber is one of the strongest natural fibers with high strength‐to‐weight and stiffness‐to‐weight ratios and can be used economically for manufacturing fiber‐reinforced composites. In this paper, bamboo fabric‐reinforced epoxy composite is manufactured and its tribological properties for load‐bearing applications are investigated. Sliding wear tests are conducted using a linear reciprocating tribometer and the effect of dry and lubricated contact conditions, applied load, sliding speed, temperature, and woven fabric direction on the coefficient of friction and wear rate are investigated. A scanning electron microscope is used to define the wear mechanisms at room and elevated temperatures. It is observed that the fabric orientation influences the mechanical and tribological performances of the composite material. Wear rate increases at higher loads and working temperatures; however, the effect of sliding speed is not remarkable, especially under lubricated contact conditions. The results present in this paper can be used for designing bamboo‐reinforced epoxy composites for load‐bearing applications, under different working conditions.
