“…3,6 Polylactic acid has been extensively studied for use in various fields such as food packaging, disposable utensils, and medical devices. [7][8][9][10] Nevertheless, the main shortcomings which are inherently low crystallization rate, low melt strength and heat deflection temperature resulting from its low glass transition temperature (Tg) restrict the use of PLA in wider application areas. 11,12 It has also several drawbacks of combustibility resulting from its inherent molecular structure as well as relatively low vapor, gas and light barrier.…”

This study aims to develop sustainable, renewable and biodegradable biocomposite films from environmentally friendly materials. For this purpose, completely biodegradable polymer composites were prepared by mixing polylactic acid (PLA) with a new source, quince peel (QP), by solvent casting method, and their structural, mechanical and thermal properties were examined. The tensile strengths of the composites prepared using QP in proportions varying between 5% (P5Q) and 30% (P30Q) by weight vary between 21.13 ± 0.80 and 12.01 ± 0.10 MPa, and their elongations at break vary between 11.33 ± 0.38 and 4.08 ± 1.06 %. As the QP contribution increased, the tensile strength and breaking elongation of these composites generally decreased, while the elastic modulus also increased. Among these composites, whose elastic modulus varies between 1040.00 ± 140.01 and 811.33 ± 13.31 MPa, it was determined that the elastic modulus (1040.00 ± 140.01 MPa) of the 20% QP added composite (P20Q) was higher than the others. When the thermal analysis of PLA/QP films were examined, it was observed that the glass transition temperatures (Tg) were between 58.54 and 51.45°C and the melting temperatures (Tm) were between 167.71 and 164.28°C, and these temperatures generally decreased with increasing QP doping. When the T50 values, which represent the temperature at which 50% of the composite materials decompose, were examined, it was found that the QP-added ones were higher than the pure composites. While this value was 317.96°C in pure PLA composite, T50 values varied between 327.92 and 340.80°C depending on the varying QP ratios. According to the XRD results performed to evaluate the crystalline properties of PLA composites containing quince bark, the crystallinity of pure PLA was determined as 19.5% and the crystallinity of composites containing 5, 10, 20 and 30 wt % QP additives was determined as 19.3, 18.3, 16.4 and 14.6%, respectively.

“…Therefore, it is of great significance to develop novel biodegradable composite materials for partial replacement of petroleum-based materials (García-Depraect et al 2022). Biodegradable composites made of completely or partially bio-resourced materials have garnered increasing interest (Marina et al 2020;Xu et al 2020;Nanni et al 2021;Platnieks et al 2021;Kong et al 2022;Mohammad et al 2023). Great efforts have been Lignocellulosic biomass fibers have been used as reinforcing fillers and substitutes in polymers for preparing green composites due to their advantages of environmentally friendly (renewable, completely or partially recyclable), low in price, available in large quantities, low density and biodegradability (Bartos et al 2020;Marina et al 2020;Dixit et al 2021;Jiang et al 2021).…”

According to their results obtained from optimizing the effects of independent variables on the mechanical properties of the bio composite sheet, the optimal formulation for the PLA, PBS, and natural fiber biopolymers blend were 48.2 wt%, 45.4 wt%, and 6.4 wt%, respectively.…”

A new class of bio-composites was developed by utilizing four kinds of lignocellulosic biomass fiber (bagasse, bamboo, rice husk, and rice straw) as filling fibers. Poly-β-hydroxybutyrate (PHB) and poly(butylene succinate) (PBS) in a mixture ratio of 7:3 were used as matrix materials with hot-press molding. The performance of the resulting composites was evaluated by compositional analyses, mechanical analysis, Fourier transform infrared (FTIR) spectroscopy, thermogravimetry, and morphological analysis. The interfacial adhesion, thermal stability, and comprehensive mechanical properties of the alkali treated bamboo/PHB/PBS composite were highest among the four bio-composites. The bending strength, tensile strength, and impact strength for alkali treated bamboo/PHB/PBS composite was 19.82 MPa, 12.97 MPa, and 4.30 kJ/m2, respectively. The thermal stability for NaOH modified bamboo/PHB/PBS composite was slightly superior to the other three composites, with the initial pyrolysis temperature of 248 °C, moderate pyrolysis speed, and the amount of pyrolysis residue (5.81%). The results showed the suitability of biomass fiber and biodegradable polymer for producing environmentally friendly composite materials.
