The impact of the nature of nanoclay on physical and mechanical properties of polypropylene/reed flour nanocomposites

Abstract

In this study, the effect of nanoclay on the physical and mechanical properties of nanocomposites was investigated. Composites based on polypropylene, reed fiber, coupling agent (maleated polypropylene, MAPP) and nanoclay were made by melt compounding and then injection molding. The mass ratio of reed fiber to polypropylene was controlled at 60/40 for all blends. The concentration was varied and set to 0, 2 and 4 per hundred compounds (phc) for nanoclay and 0 and 2 phc for MAPP. Results indicated that the tensile modulus and strength of PP/reed flour composites significantly increased with nanoclay loading. However, the impact strength and water uptake of the composites decreased by addition of nanoclay. Finally, the mechanical and physical analyses showed that the biggest improvement of these properties can be achieved for the nanoclay loading at 4 phc. The morphology of the nanocomposites has been examined by using X-ray diffraction. The morphological findings revealed that intercalation from the sample with 4 phc concentration of clay, which implies the formation of intercalation morphology and better dispersion, and the d-spacing of clay layers were improved in the composite in the presence of

Barrier, Biodegradation, and mechanical properties of (Rice husk)/(Montmorillonite) hybrid filler-filled low-density polyethylene nanocomposite films

“…A shifting of the diffraction peak to the lower angle of the clay/RH hybrid filler‐filled high‐density PE (HDPE) nanocomposites was also reported by Kord . Similar observations have also been reported by other researchers . Interestingly, the varying amounts of RH in the RH/MMT hybrid filler‐filled nanocomposite films did not affect the interlayer distance of MMT because no remarkable change was observed in the diffraction peak angles.…”

“…However, it is * corresponding author; e-mail: nbbektas@pau.edu.tr seen that these properties can be improved with different compatibilizer [8,11]. As can be seen clearly from the literature, tensile strengths and modulus of elasticity values can be increased with the addition of nanoclay to the polymer matrix [8].…”

“…These materials which are called polymer nanocomposite, the particles are spread in more homogeneous form because of the nanoscale size of particles in the polymer matrix and better holding can be achieved as the surface area is increased [5,6]. Several studies have been carried out to improve the mechanical and thermal properties of the polymer matrix adding nanoparticles with suitable compatibilizer [5][6][7][8][9]. It has been observed that the Izod impact resistance is reduced by nanosized particle reinforcement to polymeric materials [8,10].…”

A Review on Potentiality of Nano Filler/Natural Fiber Filled Polymer Hybrid Composites

“…The decrease in the water absorption and thickness swelling is observed by the hybridization of nanoclay with reed flour besides this it also upgraded the tensile properties of the whole system. Researchers also show the effect of coupling agent on mechanical and physical properties of reed flour/PP/nanoclay hybrid composite [119]. In other work, integration of nanoclay to the HDPE/rice husk system greatly enhanced their mechanical properties [15].…”
