Abstract
This work focuses on the potential use of cellulose fibers extracted from Mediterranean saltbush (Atriplex halimus) as a filler in the polymeric matrix. The fully biodegradable composites were prepared from polylactic acid (PLA) as matrix and microcellulose fibers ranging from 0 to 15 wt.%. The influence of the fiber content on the structure, mechanical, thermal, and water absorption properties was evaluated. Mechanical results indicated that fibers acted effectively as reinforcement, increasing the tensile strength and the Young’s modulus of PLA by 25 and 45%, respectively. This is due to the good stress transfer between fibers and matrix through the strong interactions that have been evidenced by Fourier Transform Infrared (FTIR) spectroscopy. The thermogravimetric analysis showed that PLA composites have a slightly lower degradation temperature than the pure PLA, but they still have favorable thermal stability. Water absorption measurements and biodegradability tests showed that the addition of fibers accelerates degradation kinetics and confirm that the prepared composites are an environmentally safe material suited for different applications.
