“…KH550 (NH 2 CH 2 CH 2 CH 2 Si(OC 2 H 5 ) 3 ), an economical organo-silane, was adopted in this study. Silane treatment has proved to be a low-cost and efficient method to endow the fiber-matrix an improved interfacial bonding [26][27][28]. It is clearly visible that raw basalt fibers were brownish in color, whereas the modified basalt fiber (MBF) displayed a light brownish color.…”

Abstract:In this work, an economical modifier silane agent-KH550-was used for surface treatment of basalt fiber. Then, a biodegradable poly(butylene succinate) (PBS)/modified basalt fiber (MBF) biocomposite was successfully developed. The effects of silane treatment and fiber mass content on crystalline structure, isothermal crystallization process and mechanical performance of composites were evaluated. The interfacial crystallization of PBS on the surface of MBF was investigated by using a polarized optical microscope (POM). The transcrystalline (TC) structure could be clearly observed and it grew perpendicular to the surface of MBF, which boosted the nucleation ability on PBS crystallization and the strong interfacial interaction between PBS and silane-treated basalt fiber. Under isothermal crystallization kinetics, the incorporation of basalt fiber enhanced the crystallization rate and reduced the crystallization half-time values of composites compared with that of neat PBS due to a heterogeneous nucleation effect. Furthermore, tensile results confirmed that the presence of MBF could greatly improve the tensile strength and modulus. The predicted interfacial shear strength (IFSS) suggested that an enhancement of interfacial bonding could be realized via interfacial crystallization, which was also verified by SEM images. The PBS/MBF biocomposites can be applied in many fields as a low-cost, lightweight, and biodegradable composite material.

“…Similar studies conducted and presented by Chen et al also showed superior strength, stiffness and impact resistance of ramie fibers reinforced PLA biocomposites over neat PLA. On top of that, surface modifications of natural plant fibers can boost the compatibility behavior on the fiber–matrix interfaces . Amongst the commonly known used modifiers, sodium hydroxide, and silane coupling agent have previously demonstrated significant positive results due to their remarkable efficiencies .…”

Improved thermal and mechanical performance of ramie fibers reinforced poly(lactic acid) biocomposites via fiber surface modifications and composites thermal annealing

et al. 2018

Ramie fibers reinforced poly(lactic acid) (PLA) biocomposites in the recent past have gained a lot of research attention for various applications due to their biodegradability, lightweight and renewable advantages. However, their low thermal stability performances and poor mechanical properties have to this date limited their industrial use. Herein, an approach to solve the two mischiefs is presented, which involved first surface modifying of ramie fibers followed by thermal annealing of the reinforced PLA biocomposites. The resultant biocomposites showed tunable mechanical and thermal resistance properties. These improved properties are ascribed to the improved interfacial bonding of the modified ramie fibers and PLA polymer, courtesy of newly introduced reactive groups onto fibers which were capable of building strong interface bonds between the polymer–fiber boundaries. More still, the thermal stability of the resultant composite is attributed to the thermal annealing condition which provided crystallized PLA molecules upon exposure to high temperatures and the steady cooling responsible for the increased degree of crystallinity in the composites as confirmed from X‐ray diffraction and differential scanning calorimetric data results. Beyond ramie fibers‐based composites reported herein, the presented methodology can also be extended to other natural plant fiber‐based composites. These modifications are capable of providing better PLA/natural fiber‐based composites for automobiles, electronics, and other related domains. POLYM.

“…The chemical modification is the common method used to improve the performances of natural fiber reinforced composites by linking the gap in compatibility between hydrophilic natural fibers and hydrophobic polymer matrix [4,8]. The chemical modification using alkaline is a simple and efficient treatment that can enhance the adhesion between lignocelluloses fiber and polymer matrix [8,9]. Rong et al 2001, studied the effect of alkaline modification on the mechanical properties of sisal/epoxy composites.…”

“…The main problem is because these filler have strong hydrophilic character, which make the interfacial adhesion between this type of filler and hydrophobic polymer matrix poor.
