“…Its biodegradability and bioenvironmental compatibility properties have made it the focus of many studies in recent years . PLLA has a melting temperature of 160°C, and good tensile properties As such, PLLA possesses wide applications as a raw material in industrial and medical applications (suture materials and orthopedic fixation devices). Kenaf fiber has been blended with different polymers, but very little has been published about PLA/Kenaf eco‐composites .…”

Effect of kenaf fiber age on PLLA composite properties

A challenge facing engineering with natural fibers is the high standard deviation of mechanical properties of natural fiber compared with synthetic fiber. Plants have a chemical and physical architecture reflective of their age. The region near the apex is more flexible than that near the base. In this paper we investigate the impact of increasing age of plant fiber on the corresponding composite. Bast fibers stems of kenaf (Hibiscus cannabinus, L.), a warm season tropical herbaceous annual plant extracted corresponding to different age, were dispersed into Poly-L-lactide (PLLA) matrix by melt blending followed by compression molding. The resulting biobased hybrid composites were characterized by X-ray diffraction (XRD), attenuated total reflectance-Fourier transfer infrared spectroscopy (ATR-FTIR), differential scanning calorimetry (DSC), optical microscopy (OM), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA) were conducted. DSC and XRD indicated that the kenaf was effective in promoting crystallization. TGA indicated that the thermal stability of composites is reduced compared with PLLA, but the older fiber sample based on 120-150 cm from the plant apex improved thermal stability compared with the rest. SEM and OM inferred good fiber dispersion while dynamic mechanical tests revealed increased modulus. POLYM. COMPOS., 35:915-924, 2014.

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.

Bioplastics are biobased polymers with two sustainability concepts: biodegradability and renewability. On the one hand, bioplastics that biodegrade to CO 2 and H 2 O in the environment can be produced, eg, avoiding litter and damage to marine organisms. On the other hand, renewable feedstocks instead of petroleum can be used, for instance, corn, sugarcane, and algae, reducing dependence on crude oil and reducing the impact on the climate. Currently, bioplastics have a market share of ∼1%, yet they experience annual growth rates in excess of 20–30%. This article highlights some key aspects associated with bioplastics, the performance of which can be tailored to meet that of petrochemical polymers or to offer new properties, eg, by blending and additivation. Important bioplastics are TPS (thermoplastic starch), PLA (polylactic acid), PHAs (polyhydroxyalkanoates), and bio‐PE, bio‐PP, and bio‐PET, which contain at least some renewable carbon.
