“…As per some of the prior studies PLA crystallizes through two different regimes with respect to two different morphologies of the crystals, α and β form [22,23]. The L-H plot in the present study also suggests similar observation, where the graphs indicate phase transformation at a particular temperature for each sample.…”

Poly(lactic acid) (PLA) is famous for its crystalline nature and ability to show exothermic crystallization (cold crystallization) peak during heating cycle of differential scanning calorimetric study. To get an insight into the mechanism of cold crystallization of PLA in its promising forms like biodegradable blend and biodegradable blend nanocomposite, a kinetic study has conducted and reported in the present study. Biodegradable blend of PLA has prepared with poly(hydroxybutyrate) (PHB). Subsequently, blend nanocomposite has prepared using organically modified layered nano silicate. Maleic anhydride has used as a reactive compatibilization agent to modify the interface of the partially miscible blend of PLA and PHB. Kinetics and mechanism of crystallization have monitored through isothermal cold crystallization method on the basis of Avrami relationship. Avrami exponent 'n' and equilibrium rate constant 'K' value has taken into consideration to quantify the crystallization rate. The halflife of crystallization and equilibrium melting point also has estimated as additional findings to confirm the estimated rate of crystallization. Variation in the energy of activation (E a ) using Arrhenius relation and regime transitions during crystallization process through Lauritzen-Hoffman (L-H) equation also have been reported.

“…Alkali treatment was also used as a pre-treatment for all subsequent treatments. To do so, the fibers were placed for 15 min in 2% NaOH at room temperature, in order to activate the hydroxyl groups on the fiber that are generally not readily accessible to react; that is, surface cleaning [19,20].…”

Rotomolded polyethylene-agave fiber composites: Effect of fiber surface treatment on the mechanical properties

et al. 2016

In this work, a comparison between different agave fiber surface treatments has been presented to improve the mechanical properties of rotomolded natural fiber composites (NFC). The fiber treatments were carried out with sodium hydroxide, 2-chlorobenzaldehyde, maleic anhydride grafted polyethylene, acrylic acid, methyl methacrylate, and triethoxy vinyl silane. In particular, a simple dry-blending technique was used to introduce agave fibers in the polymer matrix (linear medium density polyethylene). The samples were produced at 15 wt% fiber content and characterized in terms of morphology, density, hardness, and mechanical properties (tension, flexural, and impact). The results showed that surface treatments improved the homogeneity (uniform morphology) of NFC and the best mechanical improvements (77% for strength and 30% for stiffness) were obtained with maleic anhydride grafted polyethylene.

This paper describes the flexural properties of biodegradable composites made using natural fiber and biodegradable plastics. Biodegradable composites were fabricated from bamboo fiber bundles and PLA (polylactic acid) resin. In this research, effect of molding temperature and fiber content on flexural properties of bamboo fiber reinforced composites was investigated. The flexural strength of this composite increased with increasing fiber content up to 70%. The flexural strength of composites decreased at molding temperature of 180˚C. Biodegradable composites possessed extremely high flexural strength of 273 MPa, in the case of molding temperature of 160˚C and fiber content of 70%.
