(A) FT-IR spectra of CTS and the mixtures of OA and CTS at weight ratios from 1:5 to 4:5. (B) FT-IR spectra of CTS, OA-CTS, OA-CNPs, PTX, PTX-OA-CNPs, QUE, QUE-OA-CNPs, blank PMs, and PMs. (C) DSC thermograms and (D) XRD patterns of OA-CTS, PTX, PTX-OA-CNPs, QUE, QUE-OA-CNPs, physical mixture of all solid objects, and PMs.
