The COC peaks of my PLA nanocomposite has shifted to higherwave numbers ( around 20 cm-1) in comparison with the neat PLA nanocomposite. What does this shift mean and what kind of interaction does this shifting mean?
These means the intraction is found between polymer matrix and nanowires. This interaction may be a van der waals. There may a c-o-c peak become a broader or its intensity become less than that of neat spectra of polymers.
