WATER ABSORPTION, XRD AND FTIR ANALYSIS OF PBS-STARCH BLENDED HALLOYSITE COMPOSITES
Poly (butylene succinct) (PBS)/starch/halloysite nanotubes(HNT) composite was fabricated through solution casting using deionised water. The effect of HNT on the water absorption behavior of the composites has been studied and found to be decreasing with the increase in loading of HNT. The characterizations of the composites were carried out by the Fourier Transform Infrared spectroscopy (FTIR), X-ray diffraction (XRD). XRD and FTIR results indicated halloysite was successfully incorporated to PBS-Starch blend through solution casting method. XRD showed that the basal spacing of PBS-Starch increased because of the presence of halloysite. The UV Study shows the good shielding property of the blend Nanocomposites. From the Water absorption test, it is found that the water absorption tendency of the hybrid composites decreases regularly.
