“…The final material is usually non‐porous. PLA can be processed by HME alone or with the addition of other polymers as well as different organic and inorganic substances 72–84 . When the molten PLA is extruded through a sheet die and quenched on polished chrome rollers that are cooled with circulating water, PLA films (usual thickness 0.076 mm) and sheets (usual thickness 0.25 mm) are produced 23 .…”

Poly(lactic acid) (PLA) stands out as the most promising biodegradable alternative to conventional petrochemical‐based polymers for manufacturing of high‐performance materials applied in medicine, pharmacy, food, textile, and electronic industry. This review was aimed to present the conventional and up‐to‐date technologies for PLA processing including melt blending and molding, hot melt extrusion, 3D printing, foaming, impregnation, thermally induced phase separation, nano‐ and microparticles preparation, wet and dry spinning processes. In addition, the effect of the processing parameters and polymer characteristics on the properties of the final material was elaborated. Diverse possibilities to tailor properties of PLA‐based materials by variation in polymer characteristics and concentration, solvent selection, drying method, processing pressure and temperature, incorporation of bioactive components, and so on were highlighted. The examples of the relations between processing methods, parameters, and end‐product properties are given for a better understanding of all aspects that need to be perceived for fabrication of PLA‐based materials with required performances.

“…Selection of solvent for synthetized PLA or commercial PLA 3 also influenced the properties of films obtained by solvent casting method 41,80 . For instance, CHL induces greater chain mobility of the polymer while DX causes a rough surface of the film due to its slow evaporation rate 179 .…”

“…In addition, comparing with other kinds of biodegradable foaming plastic, PBS foaming materials have some excellent characters, such as adequate raw materials source and easy machinability. 11 Due to these outstanding performances, PBS is an appropriate foaming raw material and have been applied in some fields, such as the package and tissue engineering material; 12,13 however, these PBS foaming materials have large cellular size, collapsed cells, poor structural shape ability, and low mechanical strength, which restrict their widespread use in package and tissue engineering fields application. 14,15 To improve these properties, PBS is proposed to be equipped with microcellular and high mechanical strength characters.…”

This paper fabricated the cross‐linking poly(butylene succinate) foaming materials with high expansion ratio, high mechanical strength, and high degradation rate though cross‐linking and molding compression methods. With dicumyl peroxide content increasing, complex viscosity, and storage modulus appear to increase tendency. The properties of cell size, distribution, mechanical properties, and thermal conductivity all appear the first increasing and then decreasing trend with dicumyl peroxide content increasing. When dicumyl peroxide concentration is 6 wt% and azodicarbonamide concentration is 1 wt%, pure cross‐linking poly(butylene succinate) foaming material's expansion ratio and compression strength could reach 7.03 and 5.61 MPa, respectively. In addition, this pure cross‐linking poly(butylene succinate) foaming material has high degradability, and the degradation ratio could get 80% in alkaline aqueous solution.

“…Moreover, PLA undergoes gradual crystallization and enzymatic hydrolysis throughout its shelf life [ 3 ]. To overcome these disadvantages, a number of ways have been proposed for modifying PLA, such as reinforcement, addition of plasticizers or blending with other polymers [ 4 , 5 , 6 ]. The inclusion of reinforcing materials in biopolymer matrix significantly improves tensile strength and toughness of the resulting composites [ 7 , 8 ].…”

Study of the Effect of Modified Aluminum Oxide Nanofibers on the Properties of PLA-Based Films

et al. 2022

To find out whether Al2O3 nanofiller is effective in improving the characteristics of polymer composites, composite polymer films based on biodegradable polylactide and epoxidized aluminum oxide nanofibers were obtained by solution casting. Surface morphology, mechanical and thermal properties of composites were studied by SEM, IR-Fourier spectroscopy, DSC and DMA. It was shown that, below and above the percolation threshold, the properties of the films differ significantly. The inclusion of alumina nanoparticles up to 0.2% leads to a plasticizing effect, a decrease in the crystallization temperature and the melting enthalpy and an increase in the tensile stress. An increase in the content of alumina nanoparticles in films above the percolation threshold (0.5%) leads to a decrease in the crystallinity of the films, an increase in stiffness and a drop in elasticity. Finding the percolation threshold of alumina nanoparticles in PLA films makes it possible to control their properties and create materials for various applications. The results of this study may have major significance for the commercial use of aluminum oxide nanofibers and can broaden the research field of composites.
