“…The use of natural fibers for polymers reinforcement requires a strong adhesion between the fibers and the matrix (Moreno et al, 2018). This adhesion at the interface is an important issue because hydrophilic reinforcements are incompatible with hydrophobic thermoplastic matrices such as polyolefins or PLA, to a certain extent, and consequently it is important to improve the interfacial adhesion between the phases (Zhang, 2014;Essabir et al, 2016).…”
