“…[20][21][22] Nevertheless, brittle nature and unfavorable crystallization property of PLA restrict its widespread applications. 23 Traditional processing methods of PLA include hot pressing, screw extrusion, injection molding, and solution casting. Although the performance of materials can be well controlled in these manufacturing processes, the ability to control complex structure is limited.…”

The cellulose fiber was extracted from the abandoned crop sugarcane bagasse (SCB) by means of chemical treatment methods. Poly(lactic acid) (PLA) bio‐based composites with SCB were prepared through fused deposition modeling (FDM) 3D‐printing technology, and the morphologies, mechanical properties, crystallization properties, and thermal stability of 3D‐printed composites were investigated. Compared with the neat PLA, the incorporation of SCB into PLA reduces the tensile strength and flexural strength of 3D‐printed samples but increases the flexural modulus. The difference in tensile performance and bending performance is that the tensile strength of 3D‐printed samples is best when the SCB content is 6 wt%, while the flexural modulus continuously decreases as the SCB content increases. Furthermore, the effects of various printing methods on the tensile performance of 3D‐printed samples were explored via modifying G‐code of 3D models. The results indicate that the optimum SCB fiber content is identical for all printing methods except method “vertical.” Due to the fibers and molecular chains are oriented to varying degrees with altering raster angle in 3D‐printed samples, the fully oriented sample printed by method “parallel” has a better tensile strength. Besides, SCB exhibits enough high thermal decomposition temperature to meet requirements for melt extrusion processing of PLA composites, and SCB fiber is capable of promoting the crystallization of PLA.

“…The high-intensity peaks are associated with the reflections of the (110)/(200) and (203) planes, respectively, whereas the low-intensity peaks are assigned to the reflections of the (010) and (015) planes, respectively [6]. The highly crystalline plane at (110)/(200) mainly corresponds to the α -form crystals in the PLA matrix [29]. After the composite was fabricated with the incorporation of alumina in the PLA, the XRD peaks of the alumina increased in intensity with increasing filler loading, whereas the intensity of the diffraction peaks assigned to PLA became weaker.…”

This work investigates the nonisothermal crystallization and melting behavior of polylactic acid (PLA), filled with treated and untreated alumina and nano-aluminum nitride hybrid composites. Analysis by attenuated total reflectance Fourier transform infrared spectroscopy revealed that the treated fillers and the PLA matrix developed a good interaction. The crystallization and melting behaviors of the PLA hybrid composites were investigated using differential scanning calorimetry showed that the degree of crystallinity increased with the addition of hybrid fillers. Unlike the untreated PLA composites, the complete crystallization of the treated PLA hybrid composites hindered cold crystallization during the second heating cycle. The crystallization kinetics studied using the Avrami model indicated that the crystallization rate of PLA was affected by the inclusion of filler particles. X-ray diffraction analysis confirmed crystal formation with the incorporation of filler particles. The inclusion of nano-aluminum nitride (AlN) and the increase in the crystallinity led to an improvement of the storage modulus.

In situ polymerization by polycondensation was implemented to disperse crystalline nanocellulose (CNC) in poly(ethylene succinate) (PESu). The in situ polymerization technique resulted in good dispersion of the CNC nanoparticles in the PESu matrix. The polymerization kinetics were altered with increasing CNC content, causing a decrease in the polymer molecular weight. The addition of CNC particles having a large aspect ratio resulted in significant increases in the viscosity of the resulting composites, and significantly enhanced crystallization kinetics. PESu containing well‐dispersed 0.25 wt% CNC maintained the tensile properties of the matrix, demonstrating that at these very low loadings the CNC acts as an efficient nucleating agent, without compromising the mechanical properties and biodegradability POLYM.
