“…In the last decade, much attention has been focused on polymer composites based on inorganic filler (including silica) [16][17][18] and lignin or cellulose [14,[19][20][21]. Inorganic fillers such as silica are attractive reinforcements that are able to significantly improve thermal, mechanical and also chemical properties of PLA-based biocomposites [4,5].…”

In this paper, amorphous silica Syloid 244 and kraft lignin were mechanically coupled. Four hybrid materials containing silica and lignin in ratios 1:1, 2:1, 5:1 and 20:1 were prepared. As reference samples for hybrid fillers pristine silica and lignin were used. Particle size determination and microscopic observations were applied to determine dispersive and morphological properties of hybrid fillers. Fourier transform infrared spectroscopy confirmed the effective preparation of silica/lignin hybrid materials. The parameters of porous structure of examined hybrid filler were determined using the multipoint Brunauer-Emmett-Teller method and Barrett-Joyner-Halenda algorithm. Composite samples of polylactide (PLA) containing 2.5 % (w/w) of hybrid filler were extruded. Optical microscopy, wide-angle X-ray scattering and differential scanning calorimetry were applied to specify the supermolecular structure of functional PLA/hybrid composites and analyze the crystallization parameters as well as the phase transformation in PLA matrix. Silica/lignin hybrid material was found to be a filler capable of an effective crystal nucleation. The nucleating ability of silica/lignin hybrid filler in PLA matrix is related to porous properties of filler and its composition.

“…However, the addition of PMMA/silica decreases the tensile strength and elongation compared to PLM. The decrease in tensile strength might be attributed to the stress concentration effect induced by silica in the “Hard” PLA matrix [ 46 ]. The elongation tends to decreases slightly, but it is considered to have a low effect on the “soft” PnBA domain within the range of standard deviation.…”

Effect of PMMA/Silica Hybrid Particles on Interfacial Adhesion and Crystallization Properties of Poly(lactic acid)/Block Acrylic Elastomer Composites

et al. 2020

Poly(lactic acid) (PLA) is a relatively brittle polymer, and its low melt strength, ductility, and thermal stability limit its use in various industrial applications. This study aimed to investigate the effect of poly(methyl methacrylate) (PMMA) and PMMA/silica hybrid particles on the mechanical properties, interfacial adhesion, and crystallization behavior of PLA/block acrylic elastomer. PLA/block acrylic elastomer blends exhibit improved flexibility; however, phase separation occurs between PLA and block acrylic elastomer domains. Valid time-temperature superposition (TTS) measurements of viscoelastic behavior were obtained and exhibited interfacial adhesion with the addition of PMMA or PMMA/silica in PLA/block acrylic elastomer blends. In particular, the phase separation temperature was increased by the incorporation of PMMA/silica hybrid particles, which suggests a potential role for these particles in improving the phase stability. In addition, PMMA inhibits crystallization, while PMMA/silica acts as a nucleating agent, thus increasing the crystallization rate and crystallinity degree.

Classic plastics accumulate in nature causing environmental pollution, yet as a counterbalance they benefit society in many ways. They are versatile, cost‐effective, and can be tailored to have desired properties. The global environment has led to the fabrication of commodity plastics from environmentally degradable polymers. Poly(lactic acid) (PLA) is the most promising among the environmentally friendly polymers available. PLA‐based plastics have mechanical, thermal, and transparency similar to traditional plastics, and they can be molded and fabricated using the same equipment and procedures. Their material properties are enhanced through nanocomposites, compatibilizers, plasticizers, and other fillers (flame retardant, ultraviolet filter, etc.). This review summarizes mass production techniques and property reinforcements (focusing on nanocomposites and plasticizers) for PLA‐based plastics for commodity use.
