Molecular rotor dynamics influenced by the elastic modulus of polyethylene nanocomposites [PDF]
We observed that the excited-state twisting motion of 3,3′-diethyloxacarbocyanine in polymer nanocomposites (PNCs) depends strongly on the elastic modulus of medium. PNCs consist of low density polyethylene dispersed with surface-functionalized nanodiamonds with various alkyl groups.
