“…The surface damage of the fiber layer was the most obvious under the strong oxidant environment, followed by the aquaculture water and seawater environments, and the degree of damage under the weakly alkaline environment was the least.

“…and Bao et al [4] . reported that surface damage may be caused by the hydrolysis and degradation of PLA (Sun, Yufeng et al, 2022) [38] . Different erosion phenomena were observed between the spun-bonded layer and melt-blown layer, and the melt-blown layer showed more serious damage, possibly due to a smaller diameter and larger contact specific surface area.…”

“…However, the poor toughness of PLA limits its application in high-toughness occasions. [12][13][14] Thus, several efforts have been focused on PLA modification, such as blending or copolymerization.

A series of polylactide (PLA)/polycaprolactone‐based polyurethane (PCLU) blends were prepared by reactive blending of PLA with polycaprolactone diol (PCL diol) and hexamethylene diisocyanate (HDI). The reaction mechanism, compatibility, crystallization behavior and the mechanical properties of the PLA/PCLU blends were investigated. It was demonstrated that the hydroxyl group of PCL diol or PLA could react with the isocyanate (NCO) group of HDI to form PCLU or PLA‐co‐PCLU in situ, thereby improving the interfacial compatibility between PLA and PCLU phases. Phase‐separated morphology with the PCLU dispersed in the PLA matrix was observed for the PLA blends with an obscure interphase. The thermal and cold crystallization ability of PLA were retarded. PLA/PCLU blend showed higher impact strength and elongation at break compared with pure PLA. Specifically, at a 40 wt% feed ratio of PCL diol, the impact strength reached an impressive 28 kJ m−2. Notably, the shape memory performance of the blend showed a substantial improvement, achieving a remarkable shape recovery rate of 96.3% at the same 40 wt% PCL diol feed ratio. The mechanisms governing both toughening and shape memory enhancement in the blend were thoroughly elucidated.

“…These materials offer the advantage of significantly reducing the plastics' degradation time in the environment. [5][6][7] Among the polymers that deserve mention, polypropylene (PP) is widely used in the plastics industry due to its low cost, excellent properties, and ease of processing. 8,9 However, PP is a petroleum-based polymer, and its use has increased environmental damage.…”

There is a need to develop environmentally friendly materials, especially plastics, that minimize environmental pollution. In this sense, polypropylene (PP) composites were produced with 20 wt% of Macaiba almond powder (MA*) and compatibilized with SEBS-MA and EPDM-MA to carry out a biodegradation investigation of these composites. Mechanical properties (impact, tensile), heat deflection temperature (HDT), scanning electron microscopy (SEM), and Fourier transform spectroscopy (FTIR) experiments were performed. These analyses verified that the best plasticization was reached in the composites with 15% of SEBS-MA and EPDM-MA, indicating an interaction between phases. The impact strength and elongation at break of the PP/MA*/EPDM-MA and PP/MA*/SEBS-MA composites increased significantly, suggesting tough behavior. Biodegradation occurred in the soil for 120 days, and both PP/MA*/10EPDM-MA and PP/MA*/15EPDM-MA demonstrated a mass loss of about 4.68% and 4.0%, respectively. Although PP is not biodegradable, the results show that macaíba almond powder can biodegrade in the PP matrix.
