“…PLA is non-toxic, biocompatible, biodegradable, and renewable, and its mechanical properties are comparable to those of polystyrene (PS) and polyethylene terephthalate (PET). [1,5] Furthermore, PLA is easily processable into various molds using different fabrication techniques, such as electrospinning, [6] solvent casting, [7] superficial CO 2 , [8] and 3-D bioprinting. [9] Despite these advantages, its application range remains restricted to certain applications due to its high production cost, brittleness, and low thermal stability.…”

Among the commonly studied organic fillers for PLA, cellulose is the most promising. It is available in various particle sizes and sources, providing numerous options for finding a suitable match for PLA matrices. In this study, cellulose was extracted from the leaves of E. autumnalis to create a novel PLA/cellulose composite. Based on a distinguished cellulose spectrum, EA cellulose was incorporated into a PLA matrix. According to SEM results, adding 3.0 wt% EA cellulose to PLA resulted in no fiber pull‐outs. Below this content, fiber pull‐outs were observed. FTIR and TGA results indicated no significant changes in chemical structure and thermal stability of the composites. XRD, DSC, and Tensile testing results revealed an increase in the crystallinity and modulus for the 3.0 wt% composites, below this content, the crystallinity and modulus of the samples were low. Therefore, in order to obtain the composition of the composite with the desired functional properties, the ratio of the PLA to EA cellulose plays a vital role, and these have to be controlled for more effective functional properties. This study has shown that blending PLA with EA cellulose can give improved properties at 3.0 wt% EA cellulose although not optimized.

“…14,15 It also positively affects the rate of return of the material to its permanent shape and can further enhance other SME characteristics, such as the recovery stress and recovery strain. [16][17][18] While each specific research employs various methods to produce samples, for example, electrospinning, 3D-printing, extruding, melting, [19][20][21][22] and film casting, the latter method was used to obtain PLA/h-BN composites in this work. Mixing in the melted state can provides a poor filler dispersion in the polymer matrix compared to the dispersion achieved when mixing the solution.…”

The use of polylactic acid‐based composites as self‐fixing materials is a promising technology for various applications due to the shape memory effect of polylactide. In this study, hexagonal boron nitride (h‐BN) was mixed with polylactic acid (PLA) with concentrations of 0, 0.5, 1, 2, 5, and 10 wt% for subsequent film casting. The morphology, mechanical and thermal characteristics of the composite were investigated. With a high percentage of filler content, a decrease in thermal conductivity was observed. The recovery strain decreased with increasing the filler content. The amount of h‐BN had a mixed effect on the recovery stress of the composite. Thus, PLA/h‐BN composites represent a new research idea to study the influence of a heat‐conducting filler on a shape memory effect in polylactic acid.Highlights Correlation between crystallinity, thermal and shape memory properties was described Decrease in thermal conductivity was observed with the large percentage of filling The composite with 2 wt% of h‐BN exhibits optimal characteristics of SME Recovery strain decreased with the rise of filler content Amount of h‐BN had a non‐trivial effect on the recovery stress of composite
