“…It was observed that by blending glycidyl methacrylate with PLA, the elongation at break was enhanced from 3.3% to 401%. 17 This result suggests that epoxybased compatibilizers may also work for compatibilizing PGA and PBAT blends.…”

Among commercial biodegradable polyesters, poly(glycolic acid) (PGA) has been rarely investigated for packaging applications, despite its unique advantages such as 100% compostability, high degree of crystallinity, high thermal stability and high gas barrier properties. The application of PGA has been limited by its mechanical brittleness, moisture sensitivity, and high melting temperature (~240 C), restricting its processing and applications for film packaging. In this study, PGA was modified by blending with poly (butylene adipate-co-terephthalate) (PBAT) via melt-extrusion. A commercial terpolymer of ethylene, acrylic ester and glycidyl methacrylate (EMA-GMA) was selected for compatibilization. The phase morphology, rheology, thermal, mechanical and gas barrier properties of the blends were investigated. With addition of 20 wt. % EMA-GMA, the elongation of PGA/PBAT (50/50 wt. %) blends was improved from 10.7% to 145%, the oxygen permeability was reduced from 125 to 103 (cm 3 mm)/(m 2 24 h atm), and the water vapor barrier performance

“…Abdelwahab et al 71 engineered a bio-based and sustainable composite using polylactide (PLA) and organosolv lignin (OL). The multifunctional composite was fabricated using reactive extrusion in poly vinyl acetate (PVAc) and glycidyl methacrylate (GMA), which resulted in a successful, sustainable, and bio-based elastomeric composite.…”

The term elastomer is a curtailment of two words, which are elastic and polymers. Accordingly, elastomers are polymer materials with elasticity. The significant challenges hindering the development of materials for naval applications, similar to other engineering sectors, include achieving a competitive light elastomeric structure. Marine structures are susceptible to various damage responses due to various loads throughout their service life. Being flexible, elastomer has a low modulus of elasticity, exhibits higher values of failure strain and yield strength. In these regards, elastomers are attractive materials for applications that require elasticity because they offer substantial advantages compared to traditional materials. However, the low fire resistance of these elastomeric materials jeopardizes their use in some critical applications. As a result, elastomeric blends and composites containing flame retardant (FR) additives are commonly used. On the other hand, elastomers possess (i) high strength-to-weight ratio, (ii) excellent impact properties, (iii) low infrared, magnetic, and radar signatures, (iv) excellent durability, and (v) high resilience to extreme loads. Hence, the scope of this study focuses on review and awareness regarding the feasibility of marine applications of elastomers/elastomeric composites, their current scientific and technological drawbacks, and future outlooks or prospects to support several applications in the marine industry.

“…This behavior has been attributed to the reduced mobility of the polymer chains obtained by the strong filler-filler interactions and incorporation of rigid lignin moiety in the matrix that caused the composites to become more brittle [19,30]. It has also been ascribed to the aggregation of the lignin particles due to polar functional moiety in the lignin structure, resulting in poor compatibility between the components [11,51]. For instance, Szabo et al [52] observed heterogeneous phase morphology with large lignin domains in the polypropylene matrix, which resulted in poor mechanical performance.…”
