“…The presence of fillers lowered the cold transition temperatures, suggesting that fillers promote in PLA chain mobility. 27 PLA, PLA/Fiber-Filler, and PLA/Filler films melt at temperatures of 167.4°C, 165.9°C and 162.1°C, respectively. The cooling curve shows no peak for crystallization.…”

“…26 Since they can take the place of inorganic and mineral fillers as a reinforcing filler in the creation of composite materials, these agricultural waste fillers have a wide range of potential applications. 27 After being peeled, peaches are typically processed into cans. Peach peels are thus frequently dumped into the environment without being processed, resulting in waste and contamination.…”

In this study, two different peach peel powders were produced using the sieving process: with fiber (filler-fiber powder) and without fiber (filler powder). To investigate the effects of the prepared powders on the shape memory properties of PLA, PLA/Filler (wt%90 PLA: wt%10 filler) and PLA/Fiber-Filler (wt%90 PLA: wt%10 Fiber-Filler) biocomposite films were prepared by the solvent casting technique. The shape memory properties of the films, such as shape fixity ratio and shape recovery ratio, were determined by the bending test. For the PLA film, the shape fixity ratio is 81 ± 5%. When filler powders are applied, the shape fixity ratio is unaffected. However, when fiber-filler powder is added, the shape fixity ratio drops to 75 ± 1%. The shape recovery ratio for PLA film is 50 ± 7%. The shape recovery ratio increases to 54 ± 4% when filler powder is added. However, the percentage of shape recovery ratio remains the same when filler-fiber powders are added. Shape memory performance can be enhanced by adding peach peel filler powder to the PLA. The peach peel filler can be considered as a cost-effective filler to improve the shape memory properties of PLA-based biocomposites. As a result, peach peel filler reinforced PLA based composite films may be possible low-cost and biodegreadable shape memory material candidates for a variety of industries like aerospace and soft robotics.

“…Numerous papers have been published in recent years related to the modification of PLA rheological properties [28]- [31]. Many of these works focused on improving the rheological behavior of PLA in order to adapt it to a specific processing condition.…”
El processament dels materials es va realitzar per incorporació directa dels derivats de colofònia, mitjançant extrusió. A continuació, les mescles extruides van ser triturades en forma de gransa o pèl•let, per a posteriorment produir provetes normalitzades d'assaig mitjançant injecció per emotlament, les quals es van utilitzar en la caracterització.Primer estudi. Pertanyent al primer grup, sobre ús de resines de colofònia i un derivat comú (tots dos de baix pes molecular). En aquest cas es va avaluar la pròpia resina de colofònia (GR) i un derivat comú, el qual consisteix en un pentaeritritol èster de colofònia (PEGR), obtingut mitjançant esterificació dels grups carboxílics dels àcids de la colofònia amb alcohol pentaeritritol. Les anàlisis d'aquest estudi es van enfocar en l'avaluació del comportament mecànic de les formulacions, així com l'avaluació de la influència de les propietats hidrofòbiques de les resines sobre la cinètica d'absorció d'aigua de l'àcid polilàctic.
