In this work we have investigated the effect of the degree of branching of hyperbranched poly(aryl ether ketone) (expressed as HPAEK) on the fluorescence spectra of the CdS/poly(aryl ether ketone) nanocomposites. CdS/HPAEK nanocomposites have been prepared by in situ synthesis method where hyperbranched poly(aryl ether ketone) with different branch degree as the ligand. The structure identifications of HPAEK and CdS/HPAEK nanocomposites were carried out by fourier transform infrared spectrometer (FT-IR) and nuclear magnetic resonance (NMR). The particle size and distribution of CdS in HPAEK matrix were determined by high resolution transmission electron microscopy (HRTEM). The thermal properties of HPAEK and CdS/HPAEK nanocomposites have been evaluated using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Optical properties of CdS/HPAEK nanocomposites have been discussed in terms of HPAEK polymer matrix with different branch degree, which were carried out by UV–Vis absorption and photoluminescence spectroscopy.
