Speech Title: The Effects of Nanoclay & Tin(IV) Oxide Nanopowder on Morphological, Thermo-mechanical Properties of Hexamethylene Diisocyanate Treated Jute/Bamboo/ Polyethylene Hybrid Composites
Abstract: Jute cellulose composite (JCC), bamboo cellulose composite (BCC), untreated hybrid jute-bamboo fiber composite (UJBC), and jute-bamboo cellulose hybrid biocomposite (JBCC) were fabricated. All cellulose hybrid composites were fabricated with chemical treated jute-bamboo cellulose fiber at 1:1 weight ratio and low-density polyethylene (LDPE).The effect of chemical treatment and fiber loading on the thermal, mechanical, and morphological properties of composites was investigated. Treated jute and bamboo cellulose were characterized by Fourier transform infrared spectroscopy (FTIR) to confirm the effectiveness of treatment. All composites were characterized by tensile testing, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Additionally, surface morphology and water absorption test was reported. The FTIR results revealed that jute and bamboo cellulose prepared are identical to commercial cellulose. The tensile strength and Young's modulus of composites are optimum at 10 weight percentage (wt%) fibers loading. All cellulose composites showed high onset decomposition temperature. At 10 wt% fiber loading, JBCC shows highest activation energy followed by BCC and JCC. Significant reduction in crystallinity index was shown by BCC which reduced by 14%. JBCC shows the lowest water absorption up to 43 times lower compared to UJBC. The significant improved mechanical and morphological properties of treated cellulose hybrid composites are further supported by SEM images. Hybrid composites were fabricated by hexamethylene diisocyanate (HDI) treated jute–bamboo fiber, nanoclay, tin(IV) oxide nanopowder, and low-density polyethylene. The composites were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis, and differential scanning calorimetry. Surface morphology, tensile testing, and water absorption test were also reported. FTIR results revealed that treated fiber had covalence bonding with polymer matrix which enhanced mechanical properties. All HDI treated hybrid composites showed significant improvement in activation energy, lower crystallinity index, significant high tensile strength, and Young's modulus compared to untreated hybrid composites. All treated hybrid composites also showed extreme low water absorption. The addition of nanoclay or tin(IV) oxide into treated hybrid composites had a negative impact on thermal-mechanical properties. Surface morphological results revealed the bonding condition among hybrid composites.
Prof Hajime Hirao, City University of Hong Kong, Hong Kong, China
Hajime Hirao received his BEng and MEng degrees from Kyoto University
and his PhD from The University of Tokyo. He underwent his postdoc
training at The Hebrew University of Jerusalem, Emory University, and
Kyoto University. Prior to that, he worked for three years on
computer-assisted drug design at the Novartis institute in Japan. Before
joining City University of Hong Kong, he worked as faculty at Nanyang
Technological University in Singapore. Over the years, he has been
interested in computational and theoretical aspects of chemistry,
especially chemical reactions. One of the major goals of his research is
to figure out how difficult chemical transformations can be achieved
using simple catalytic platforms built from earth-abundant elements.
Dr. Hirao's research applies quantum chemistry, multiscale models, and many other computational chemistry techniques to a variety of complex molecular systems of practical importance such as transition-metal catalysts, metalloenzymes, drugs/drug targets, porous materials, and nanomaterials. Using computational approaches and often with experimental collaborators, his group seeks to derive key insights into chemical reaction mechanisms and bonding patterns of complex molecules, with the ultimate aim of designing new functional molecules and materials. He is also interested in developing new concepts and computational methods that may enhance our understanding of chemistry or improve the efficiency of computational analyses.
