  journal={Composites Part A: Applied Science and Manufacturing},
Abstract We investigated the nano-mechanical behaviour of rice husk biochar (RHBC)/starch polymer composite using the amplitude modulation-frequency modulation (AM-FM) mode available within the atomic force microscopy. The interaction of biochar with the starch matrix in the interfacial region, the surface morphology and viscoelastic properties of the composite were studied through AM-FM mapping. The Young’s modulus of the biochar-starch polymer composites was correlated with the biochar dosage…
