Both techniques demonstrated that 3 and 5% w/w talc incorporation increased significantly (p < 0.05) TPS yield stress.
Well dispersion and distribution of nanoparticles within the matrix, attributed to good starch-talc compatibility, allow TPS materials reinforcement (Lim, Lee, & Tay, 2009).
Particlematrix interfacial adhesion could be associated to the edge surfaces which have hydrophilic groups such as -SieOH and -MgeOH (Chabrol et al., 2010).
In addition, Ferrage et al.
(2002) reported the presence of electronegative sites on talc tetrahedral sheets propitious to form hydrogen bonds with polypropylene methyl groups.
Similar interaction could be expected for composites based on TPS and talc nanoparticles.
