“…Polymers 2020, 12, x FOR PEER REVIEW 3 of 20 been reported that silica disperses well in PLA and results in improved mechanical and thermal properties, and also enhances the crystallinity of the structures [30][31][32]. Moreover, since silica is reported to have high silanol groups, siloxane bridges, and hydroxyl groups [12], it can be easily functionalized, opening pathways for several applications such as biomedical, separation, catalysis, and sensors [17,33].…”

Due to the significant properties of silica, thermostatics can be enhanced using silica-additives to maximize the quality of polymer compounds and transform plastics into tailored properties. The silica additives can enhance the handling and quality performance of composites and thermoplastic polymers due to their diverse potential. Besides, using silica as an additive in different characteristics can allow granulates and powders to flow easily, minimize caking, and control rheology. On the other hand, the eruption of 3D printing technology has led to a massive new waste source of plastics, especially the polylactic acid (PLA) that is associated with the fused deposition modeling (FDM) process. In this paper, the impact on the mechanical properties when silica is mixed with waste PLA from 3D printing was studied. The PLA/silica mixtures were prepared using different blends through twin extruders and a Universal Testing Machine was used for the mechanical characterization. The result indicated that increasing silica composition resulted in the increase of the tensile strength to 121.03 MPa at 10 wt%. Similar trends were also observed for the toughness, ductility, and the yield stress values of the PLA/silica blends at 10 wt%, which corresponds to the increased mechanical property of the composite material reinforced by the silica particles. Improvement in the mechanical properties of the developed composite material promotes the effective recycling of PLA from applications such as 3D printing and the potential of reusing it in the same application.

“…When 1 wt% F G is added into PLA matrix, there is a significant improvement in value of Δ H m is noticed which demonstrates that F G enhanced the formation of PLA crystals. It is fact that the addition of F G enhanced the crystalline ability of PLA 29 . For DCP modified samples T g , T m1, T m2 , and T cc are almost unchanged with PLA/1 F G, whereas the values of Δ H m and Δ H cc progressively reduced to around ~30.8 and ~ 23.1 J/g (PLA/D/3 F G), respectively.…”

Blending of poly (lactic acid) (PLA)/functionalized gum arabic (FG) in presence of dicumyl peroxide (DCP) presents a simple process to produce film using melt extrusion (recycle time ~ 4 min, screw speed ~60 rpm) at 180°C with tailored characteristics. The FTIR investigation shows that the confirmation of grafting of PLA chains on FG through formation of new C─C linkage. Properties of fabricated films such as morphological, mechanical, UV barrier and contact angle are examined to develop film with improved interfacial interaction, increased toughness, UV–C blocking effect (~95%) and hydrophobicity (~14%). Polarized optical microscopy (POM) studies reveal that PLA/1FG with and without DCP has more crystal density as compared to PLA at 120°C. This melt extrusion permits straightforward, feasible bionanocomposite film and has great potential as a modification with DCP assists to overcome particular drawbacks of FG.

“…Bioderived polylactic acid (PLA) features good biodegradability ( Xie et al., 2020 ; Zhang et al., 2020 ), high transparency, high mechanical strength, low shrinkage, and ease of processability, making it one of the most commercially valuable bio-sourced polymers ( Vahabi et al., 2018 ; Wen, 2019 ). As a result, PLA has been extensively used in packaging, electric and electronic, transport fields, and so forth.…”
