摘要: Thermoplastic starch (TPS) reinforced by 1 wt % nanofiber cellulose (NFC) reinforcing from water hyacinth was produced. Ultrasonic vibration time (UVT) applied to bionanocomposites during gelation for 0, 15, 30 and 60 min. Morphology of the NFC investigated using Transmission Electron Microscopy (TEM). Scanning (SEM) tensile tests were performed identify fracture surface determine mechanical properties bionanocomposites, respectively. The Crystallinity index (CI) untreated treated measured X-ray Diffraction (XRD). average diameter 10–20 nm. maximum strength (TS) modulus elasticity (ME) bionanocomposite 11.4 MPa 443 respectively, after min UVT. This result supported SEM which indicated good dispersion compact structure.
