Dielectric studies of amylose, amylopectin and amylose-stearic acid complexes

► Dielectric property of amylose, amylopectin and amylose-stearic acid complex. ► Activation energy for CH2OH dipole rotation sensitive to molecular structure. ► Study of chain backbone local reorientation dynamics. ► Effects of complex formation on dynamics explored. ► Effect of gel structure in complex on dielectric behaviour explored.
