WebOct 16, 2024 · Interestingly, reactive extrusion of PLA/PBS/1D F CH nanobiocomposites shows an increase in both Mn and Mw by ~16 and ~51%, respectively, and this could be due to the formation of some cross-linking/branching sites, which is also referred to as an improvement in the value of gel content, as mentioned in the previous section. WebApr 17, 2015 · Second, a reactive extrusion process was developed to covalently anchor dPHB onto the main chain of PLA. PLA with 20% (w/w) grafted dPHB demonstrated an impressive elongation at break of 538%, 66 times higher than that of pure PLA and significantly higher than the elongation at break of the corresponding physical blend.
WebThe blending was conducted by a solvent-free reactive extrusion. The incorporation of cardanol resulted in an enhancement of the compatibility evidenced by the decrease of ABS nodules size within PLA from few micrometres to several tens of nanometres and the convergence of both polymers Tα around 68.5°C. WebOct 16, 2024 · For PLA/PBS/1DFCH, the crystallization rate and nucleation density of PLA are increased because of cross-linked/branched structures are developed, which acted as nucleating sites. Therefore, the present work facilitates a simple extrusion processing with a combination of balanced thermal and mechanical properties, improved hydrophobicity …
