Mechanical, physical and tribological characterization of nano-cellulose fibers reinforced bio-epoxy composites: An attempt to fabricate and scale the ‘Green’ composite

Ni-P composite coatings were prepared on cellulose fiber surface via a simple electroless Ni-P approach. The metal-coated extent, dispersion extent of micro or nano cellulose fibers and crystalline structure of Ni-P composite coatings were investigated. The homogeneous hollow composite coatings and metal-coated extent of micro or nano cellulose fibers were improved with the increase in ultrasonic power, and the ideal composite coatings were obtained as ultrasonic up to 960 W. The metallization for cellulose fibers enhanced the dispersion extent of micro or nano cellulose fibers. A uniform coating, consisting of the hollow coating on cellulose fibers surface, could be obtained. At the same time, metallization did not damage the original structure and surface functional groups of cellulose fibers. The concentration of cellulose fibers and ultrasonic power had a direct influence on the metal-coated extent of cellulose fiber surface. The metal-coated extent, dispersion extent of micro or nano cellulose fibers and crystalline structure of Ni-P composite coatings exhibited excellent properties as the concentration of cellulose fibers and ultrasonic power were 2 g/L and 960 W, respectively.

Properties Of Composites

Polypropylene (PP) based green composites containing 10, 20, 30, 40 and 50 wt% of cellulose fibers (CFs) which were extracted from rice straw were successfully prepared by melt blend method. The CFs washed with H2O2 after alkaline extraction showed lower water absorption than that not washed with H2O2. The thermal, mechanical, and biodegradation properties of composites were also investigated. The 10% weight loss temperature of the composites was decreased with the increasing CFs content, but all the composites showed over 300°C. Young’s modulus and flexural properties of PP were improved by blending PP with CFs. The pure PP showed no degradability, but the PP/CFs composites degraded from about 3 to 23 wt%, depending on CFs content after being buried in soil for 50 days. These PP/CFs composites with high thermal, mechanical properties and biodegradability may be useful as green composite materials for various environmental fields.

AbstractComposites from some novel polyimide and commercial epoxy were prepared aiming to improve the thermal behavior of epoxy resins. Two diamines namely 4-4'-diamino-4''-hydroxytriphenyl methane (DHTM) and 4-4'- diaminotriphenyl methane (DTM) were synthesized by reacting aniline and aldehydes according to a reported method. The synthesized diamines were blended with commercially available epoxy 1, 4-butanedioldiglycidylether (BDDE) to synthesize model epoxy amine networks which were compared with polyimideepoxy composites. The polyimides were synthesized by reaction of these diamines with aromatic anhydride namely 3,3',4,4'-benzophenone tetracarboxylic acid dianhydride (BTDA). These synthesized polyimides were dispersed in epoxy diamine networks to prepare composites. All the monomers and composites were characterized by making use of various analytical techniques including FTIR, NMR, TGA, DSC and XRD. Presence of hydroxyl group in the diamine helped in better dispersion of polyimide leading to high Tg and high char yield at 600 °C.
