“…4 Screw pine root fiber reinforced soy-PVA (SSP) composite showed tensile and flexural strengths of 39.7 and 37.6 MPa respectively, whereas tensile and flexural moduli values of 1026 and 1008 MPa, respectively, indicating that the hybrid resin and screw pine fiber have a remarkable bond. 12 Strong bonds between the fibers and the matrix are created by the subsidiary -OH and additional functional groups with some dipole moment in PVA and cellulosic fiber, and the carboxylic and amine groups of soymilk protein. 17 Whereas in case of screw pine-PVA composite (SP), lower values of tensile and flexural strengths (around 28.9 and 20.1 MPa respectively) and tensile and flexural moduli (787 and 882 MPa, respectively) were obtained which could possibly be due to insufficient wetting of fiber by PVA and also quick moisture absorption.…”

Screw pine root fibers are engineering fibers that have yet to be explored in terms of its chemistry with bio‐resin in biodegradable composites to replace nonbiodegradable thermoplastics used in packaging, automobiles, furniture, and industrial sectors. Screw pine root fibers are reinforced with soy, poly(vinyl alcohol), and soy‐poly(vinyl alcohol) resin systems in this work to create a variety of composites. Composites demonstrated highest amount of tensile strength at around 39.7 MPa, 37.6 MPa of flexural property, along with an impact strength around 12.4 kJ/m2. The thermal solidity of the optimized material was determined to be 235°C. After 24 hours of immersion, the composite had the lowest water absorption of 18.4%. All composites were shown to be biodegradable, losing about 54.2%–72.9% of their original mass after 60 days in soil burial. Unique characteristics such as the use of low‐cost agricultural materials, water‐based resin, stable composite, and properties such as moderately strong, safe disposal after service periods make these manufactured composites market feasible as consumer‐friendly/ecofriendly green products.Highlights Screw pine root fibers were extracted from waste roots and used as reinforcement. The tensile strength of the composite was achieved as 39.7 MPa. The water absorption of hybrid composite was found 30.8% after 24 h. After 60 days under soil burial, composite lost 67.5% of its original weight Developed composites can be good alternant for nondegradable thermoplastic.

The use of biodegradable polymers in the plastics industry has been increasing in recent years. The study of the chemical, physical, thermal, and mechanical properties of films based on biodegradable components is of interest to technologists because these properties determine their applicability for food packaging. In this work, films based on natural polymers such as linseed mucilage (LM) and chitosan (CH), as well as poly(acrylic acid) (PAA) were obtained through the casting method and using V‐50 as the initiator. The films were characterized through Fourier Transform Infrared spectroscopy, and thermogravimetric analysis, and their water absorption and swelling capacity, and thermal and mechanical properties were determined. Homogenous flexible, translucid, amber‐colored films, with low absorption and solubility in water were obtained. It was demonstrated through Fourier Transform Infrared analysis the chemical interaction between C–H, CO, and C–O chemical groups of LM, CH, and PAA. In addition, films showed high resistance to thermal decomposition between 125 and 425°C. The mechanical tests of tension allowed the composition of LM in the film, the behavior variates between a plastic and/or elastic material and with tensile strength (Rm) values between 10.8 and 16.4 MPa and elastic modulus (E) values between 56.2 and 169.2 GPa, we observed that at higher quantities of LM and thickness, both E and Rm tend to increase, while %EL decreases. This led us to conclude that the material transitioned from ductile and malleable to rigid and brittle. The films obtained with different ratios of LM/CH/PAA may exhibit a semi‐interpenetrating polymeric networking type morphology.Highlights Thermal and mechanical properties are of interest in food packaging materials. Water absorption can impact the packaged food. Films can be processed on existing machines for conventional plastics. Some conventional plastics could be replaced by these biodegradable films. Biodegradable films are of great interest to the industry of food packaging.

To address the difficulty posed by non‐biodegradable thermoplastics, scientists are focusing on solid waste management research. Waste vetiver root fibers reinforced in polymerized soy matrix biomass composites were fabricated and tested for biodegradability and sustainability in different natural decomposing conditions like seawater aging and fungal and termite attacks. This study reports and compares the dimensional changes caused by these attacks, as well as the moisture absorption of vetiver‐soy and alkali‐treated vetiver‐soy composites at different relative humidity. After‐degradation characterizations included Fourier transform infrared spectroscopy and SEM examinations, as well as weight loss, which gave additional insights into the degradation mechanism. The tensile strength of degraded samples decreased as the degradation duration increased. Mechanical properties like Izod impact strength, dynamic mechanical analysis and moisture absorption also provided insights into the structural firmness of the fabricated composite. This research contributes to a better knowledge of the bio‐deterioration process of cellulosic vetiver‐soy biocomposites under various situations, and to check their functionality in furniture and packaging industries. © 2024 Society of Chemical Industry.
