“…Besides blending method by mixing physically inorganic ferromagnetic powder with conducting polymer powder, several approaches such as electrochemical and in-situ chemical polymerization have been reported to prepare conducting polymer film with ferromagnetic properties and nanocomposites with coreshell structure ( Chen,et al, 2005;Podlaha and Landolt, 1997). Nanomaterials dramatically different from their bulk or atomic counterparts have attracted much interest due to their unique physicochemical properties for a wide range of potential device applications such as UV lasers, solar cells, high-sensitivity chemical gas or volatile organic compound sensors, and DNA sequence sensors (Castro, et al, 2000;Wetzel, et al,2003;.…”

ABSTRACT. We report on synthesis of two highly disperse nanoparticles viz. Fe 2 O 3 & f-Fe 2 O 3 using chemical reduction method. Reaction was initiated to mix solution A (i.e. Fecl 3 6H 2 o) into solution B (i.e. Fecl 2 4H 2 o) together under the presence of ammonium to develop nanoparticles. Mechanical properties of above mentioned nanoparticles filled with polyester polymer nanocomposites were fabricated to assess the possibility of using this filler as a new material. Methacryloxypropyl was used as a functionalization agent to prepare f-Fe 2 O 3 nanoparticles. Mechanical properties of f-Fe 2 O 3 nanocomposites were improved with the help of functionalization when compared with Fe 2 O 3 nanocomposites. A functionalization of nanoparticles favours the composite fabrication with a lower curing temperature as compared to the as-synthesised nanoparticles filled polyester nanocomposites. Thermogravimetric analysis showed an increased thermo-stability of f-Fe 2 O 3 nanoparticles filled polyester nanocomposites as compared to the Fe 2 O 3 nanoparticles filled counterparts. Mechanical and thermal properties were increased due to the homogeneous particle dispersion and chemical bonding between nanoparticles and polyester matrix. The nanoparticles become magnetically harder after incorporation into the polyester resin matrix.

“…[18][19][20][21][22][23][24][25] In the automobile industry, an increased need to replace fossil-based materials with renewable resources has led to the interest in reinforcing polymers with natural fibers. 4,26 For example, Toyota Motor Corporation recently used some of these properties in their production of door panels from polypropylene/kenaf blends. [26][27][28][29] Incorporating kenaf in the manufacture of automotives not only increased their biodegradability but also reduced their weight and enhanced their noise absorbent ability.…”

Bast fibers from stems of kenaf (Hibiscus cannabinus, L.), a warm-season tropical herbaceous annual plant, were dispersed into poly-L-lactide (PLLA) matrix by melt-mixing followed by compression molding. Low fiber fractions (1-5%) were investigated. The composites showed a slight lowering of thermal stability when evaluated by thermogravimentric analysis. X-ray diffraction and differential scanning calorimetry indicated an influence of kenaf on the crystallization of PLLA. The fiber dispersion in the polymer matrix was established by polarized optical microscopy. Scanning electron microscopy showed good fiber-matrix adhesion as revealed by the combination of dispersion, interaction, and crystallinity, which enabled an increase in the mechanical properties of the composite that scaled with concentration.

“…Various temperatures of 140, 150, 160, 170, 180, 190, and 200 o C were maintained in the region from the hopper to the die, while the screw speed was kept constant at 150 rpm. The end pressure of the screw was changed as a function of fiber content: 9.9 kg f cm -2 for plasticized CDA, 12.6 kg f cm -2 for CDA/kenaf (9/1), 14.5 kg f cm -2 for CDA/kenaf (7/3), 16.1 kg f cm -2 for CDA/kenaf (5/5), respectively. The extruded product was passed through the cooling water and pelletized.…”

“…In particular, it is known that a 1 ha kenaf cultivation area can absorb about 30-40 tons of CO 2 during one cultivation cycle. 15,16 The natural fiber was not easily mixed due to its low density, and the filling content of the fiber could not be increased. In order to increase the filling content of kenaf in the CDA and to compatibilize the kenaf and CDA, the kenaf was sized with poly(vinyl alcohol)(PVA) solution.…”

Preparation and physical properties of the biocomposite, cellulose diacetate/kenaf fiber sized with poly(vinyl alcohol)

Cellulose diacetate (CDA)/kenaf fiber biocomposites were prepared using a melting process. In order to increase the fiber density and compatibilize the kenaf fiber with CDA, the fiber was sized with poly(vinyl alcohol)(PVA). The sized kenaf fiber was compounded with the plasticized CDA using a twin screw extruder, and the optimal processing conditions were determined. The incorporated kenaf fiber improved the mechanical and thermal properties of CDA. In the case of the composites containing 30 wt% kenaf fibers, the tensile strength and modulus increased almost 2 and 3 fold, which were 85.6 MPa and 4831 MPa, respectively. The PVA treated kenaf fiber showed better adhesion to the CDA matrix.
