“…The results showed that SAN-g-MAH was the most effective compatibilizer [35]. Wang et al [36] also used PC to toughen PLA. Poly (butylene succinate-co-lactate) (PBSL) and epoxy (EP) were used as compatibilizers.…”

Abstract. Polylactic acid (PLA), one of the well-known biodegradable polyesters, has been studied extensively for tissue engineering and drug delivery systems, and it was also used widely in human medicine. A new method to synthesize PLA (ring-opening polymerization), which allowed the economical production of a high molecular weight PLA polymer, broadened its applications, and this processing would be a potential substitute for petroleum-based products. This review described the principles of the polymerization reactions of PLA and, then, outlined the various materials properties affecting the performance of PLA polymer, such as rheological, mechanical, thermal, and barrier properties as well as the processing technologies which were used to fabricate products based on PLA. In addition, the biodegradation processes of products which were shaped from PLA were discussed and reviewed. The potential applications of PLA in the medical fields, such as tissue engineering, wound management, drugs delivery, and orthopedic devices, were also highlighted.

“…To increase thermal resistance, PLA can be blended with PC. The adhesion between these two polymers is weak due to interfacial tension and weak entanglements [62][63][64].…”

“…It is known that thermal treatment induces exchange reactions that lead to the formation of copolymers with a final structure that is also affected by parallel decomposition reactions, mainly the loss of carbon dioxide and ethylene carbonate (EC) [64,65]. Therefore, it is predicted that PLA and its blends will have some kind of bonding reaction with PC, weak-to-medium in strength.…”

Abstract:One of the most essential components of the fused deposition modeling (FDM) additive manufacturing (AM) process is the build plate, the surface upon which the part is constructed. These are typically made from aluminum or glass, but there are clear disadvantages to both and restrictions on which materials can be processed on them successfully. This study examined the suitability of heated aluminum-polycarbonate (AL-PC) composite print beds for FDM, looking particularly at the mechanical properties, thermal behavior, deformation behavior, bonding strength with deposited material, printing quality, and range of material usability. Theoretical examination and physical experiments were performed for each of these areas; the results were compared to similar experiments done using heated aluminum and aluminum-glass print beds. Ten distinct materials (ABS, PLA, PET, HIPS, PC, TPU, PVA, nylon, metal PLA, and carbon-fiber PLA) were tested for printing performance. The use of a heated AL-PC print bed was found to be a practical option for most of the materials, particularly ABS and TPU, which are often challenging to process using traditional print bed types. Generally, the results were found to be equivalent to or superior to tempered glass and superior to standard aluminum build plates in terms of printing capability.

“…Generally, it is synthesized through ring-opening polymerization of lactides or direct condensation processes of lactic acid monomers which are derived from the fermentation of sugar feed stocks [1,2]. In the present, PLA is one of the most popular biodegradable polymers due to several excellent reasons; high mechanical strength, renewable product, biocompatibility, fully biodegradation within a few weeks, transparency, gas permeability, and easy processability [3][4][5]. According to these advantages, PLA which can be potentially applied in many fields such as tissue engineering, drug delivery system, automobile, food container, and film packaging becomes a promising and outstanding bio-based material for replacing petroleum-based plastics, e.g., polyolefins (PE and PP), polystyrene (PS), and poly (ethylene terephthalate) (PET) as well [6][7][8].…”

Polylactide (PLA) and its blend films with and without a compatibilizer in the presence of poly(butylene adipate-co-terephthalate) (PBAT) and talc were prepared through a twin-screw extruder. The effects of PBAT, talc, and various contents of compatibilizer on thermal and morphological properties as well as crystallization of these blends were investigated. PBAT and talc were used as a flexible polymer and a nucleating agent at 10 mass% and 1 phr, respectively, whereas methylenediphenyl diisocyanate was used as a compatibilizer at different amounts (1-7 mass% based on PBAT contents). Isothermal crystallization behaviors and kinetics of neat and nucleated PLA blends were evaluated by differential scanning calorimeter and polarized optical microscope. The Avrami and Arrhenius equations were used to investigate the crystallization kinetics. The results revealed that the presence of PBAT and talc in the films led to an increment of crystallization rate of PLA via a synergistic effect under isothermal crystallization conditions. However, the crystallization rate significantly decreased with increasing the crystallization temperature (T c ). These results were in agreement with crystallization kinetic and morphological studies, suggesting that the crystallization behaviors, kinetics, and mechanisms of PLA were affected by these factors.
