Characterization of Bionanocomposites PHB, PEG and Organophilic Clay
In this study, it was investigated the structural and morphological characteristics of bionanocomposites of poly (3-hydroxybutyrate) (PHB), containing 5% polyethylene glycol (PEG), 1% and 3% two types of organoclays (Cloisite 20A and vermiculite). The systems in the form of films were prepared by the method of intercalation solution. The films were characterized by X-ray diffraction (XRD) spectroscopy and Fourier transform infrared (FTIR). It was observed that, according to the type of clay used, the systems showed intercalated structures or partially exfoliated ones. Regarding the FTIR results, they indicated that the addition of different clays to the PHB/PEG blend did not promote significant changes in the chemistry of the polymer matrix.
