Randomized trial explores thermoplastic properties of lignocellulosic materials derived from unsaturated acids, indicating potential as sustainable alternatives.
Key Points
This research aims to evaluate the properties of thermoplastic materials derived from unsaturated fatty acids and lignocellulosic sources.
Modified pine sawdust and microcrystalline cellulose with unsaturated acids (oleic, linoleic, sorbic)
Characterization using FTIR, XRD, solid-state 13C NMR, TGA, DSC, TMA, SEM, and tensile testing
Compared properties of six bioplastics derived from different fatty acid esters.
Oleate and linoleate esters showed mechanical properties comparable to some fossil plastics and bioplastics, with similar tensile strengths and elongation at break.
Sorbate esters demonstrated inferior properties compared to oleate and linoleate esters.
Thermoplastic materials can be created using unsaturated fatty acids derived from plant-based lignocellulose.
