摘要: Poly (butylene succinate) (PBS) was etherified by polyethylene glycol (PEG), and blended with carboxymethylcellulose(CMC). A novel liquid composite(PEG/PBS)-CMC was successfully prepared in water solution. The interaction mechanism of (PEG/PBS) -CMC composite was investigated by molecular simulation. The results showed that the desired structure of PEG/PBS with good hydrophilicity was achieved. Molecular simulation displayed that the polarity and flexibility of PEG/PBS was enhanced by introducing PEG to PBS. The interactions of (PEG/PBS) -CMC were hydrogen bonding, van der Waals, hydrophobic bond and adsorption. This results were explained by the deviation of absorption peak frequency on functional groups such as -OH, -OCO-, -COOH and -C-O-C-in Fourier transform infrared (FTIR) and the binding energy transfer of C and O element in X-ray photoelectron spectroseopy (XPS). Non-covalent interaction existed between composites displayed in polarizing optical microscope (POM) and X-ray diffraction (XRD). The closely integrated interface of (PEG/PBS) -CMC in scanning electron microscope (SEM) showed that the binding forces and the compatibility were enhanced after etherification modification.
