There can be observed an increase of storage modulus at 20°C when adding 1 wt% of particles to the neat PBAT and a further increase when increasing clay content to 3 wt%. Thus, an enhancement of storage modulus of 125% is achieved for the nanocomposite with 3% modified bentonite (E′ = 360 MPa) compared to the neat matrix (E′ = 160 MPa).
