“…An interlocking texture structure, cracks, and particle agglomeration are evident on the snail shell nanoparticle-, montmorillonite-, and kaolinite-filled greenpoxy nanocomposite fracture surfaces. It is known that the incorporation of fillers often influences the structure of the polymer, which may improve or inversely affect the final material properties [ 4 , 43 ].…”

“…In particular, commercial fillers such as carbon-based fillers (calcium carbonate CaCO 3, carbon nanotube, graphite), talc, montmorillonite, and kaolinite have been widely used to improve polymeric properties, which helps to reduce the cost of the expensive polymetric matrix and eventually reduces production costs [ 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. Among the filler materials mentioned above, carbon-based reinforcement materials such as calcium carbonate CaCO 3 are the most used because they are readily available and exhibit excellent thermal and mechanical strength with good reinforcement properties [ 3 , 4 ]. This carbon-based material is obtained from different sources, including rock, human, and animal waste, using various nanotechnology methods, and their particle sizes and chemical and thermal properties have been evaluated.…”

This study investigated the comparative reinforcement effect of Achatina fulica snail shell nanoparticles, montmorillonite, and kaolinite nanoclay on greenpoxy. Greenpoxy nanocomposites of snail shell nanoparticles, montmorillonite, and kaolinite nanoclay were developed separately, with the nanofiller content ranging from 1 to 3% by weight. Specimens of the nanocomposites with different percentage weights of the nanoparticles were prepared using the resin casting method. Mechanical properties, such as the tensile strength, stiffness, hardness, and impact strength, and water absorption properties of the specimens were evaluated experimentally. It was observed that the incorporation of nanoparticles improved the mechanical properties of pure greenpoxy irrespective of the percentage weight, source, and type of reinforcement. Significantly, the loading of 1 wt.% of snail shell nanoparticles offered superior properties in most cases. Protein fibers and high-concentration calcium carbonate in snail shell nanoparticles, uniform dispersion, and excellent matrix/snail shell nanoparticle adhesion provided a strong structure, resulting in the high strength, stiffness, and decreased water uptake of the composites. The superior properties observed in snail shell nanoparticle composites suggest that this naturally sourced nanofiller can be used as a potential substitute for montmorillonite and kaolinite clays.

Nanoclay - Recent Advances, New Perspectives and Applications

View full text Add to dashboard Cite

The recent techniques for improving polymer-based composite properties using nanoclay infusion have been reviewed in this chapter. The recent progress in the printing of thermoplastic composite infused with different sizes of particles was reviewed. The processing of infusing clay into natural fiber and recent advancements in the printing of thermoplastic composite infused with nanoclays at different loading ratios also was discussed. Valid information on different apparatuses for determining mechanical properties, temperature dependence storage modulus, and tan α of the developed materials were provided. The loading effect of clay on the mechanical properties, temperature dependence storage modulus, and tan α of composite and nanocomposites was reviewed. Specific emphasis on printed nanocomposite application in gears and related engineering fields is considered. The innovative scope of infusing nanoclay for developing composite with improved mechanical properties, temperature dependence storage modulus, and tan α was discussed. Similarly, the application of clay-reinforced composite with the revolutionary scope of infusing nanoclay for different applications was suggested.

Effect of Nano-Fillers on Tensile Properties of Biopolymer Films

et al. 2018

There is a growing interest in biopolymers due to their biodegradability, biocompatibility, and edibility. Biopolymer applications include food packaging, biomedical applications, and as structural materials. However, their mechanical properties are limiting. Current research is focused on modifying the physical and chemical properties of biopolymers for better performance and broader applications. The addition of nanofillers has been proposed as a way to modify mechanical properties of biopolymers. This work is focused on biopolymers as edible materials, therefore biopolymers and fillers must meet this requirement. In this study, microcrystalline cellulose (MCC), nanocrystalline cellulose (CNC), CaCO 3 nanoparticles, hydrophilic nanoclay and hydrophobic nanoclay were separately added as fillers to the polymers, konjac glucomannan (KGM), hydroxypropyl methylcellulose (HPMC), and zein to investigate their effect on tensile properties of composite films. Tensile properties were measured by dynamic mechanical analysis (DMA) obtaining stress (σ), strain (γ), and Young's modulus (E).Results revealed significant differences between neat polymers. Fillers, at 2% w/w, affected film properties depending on their size, shape, and surface chemistry. Good dispersibility and the extent of polymer-filler interactions controlled the effect of nanofillers on film properties. Nanosize, high aspect ratio, and hydrophilicity showed significant effects on tensile properties over micro-size, low aspect ratio, and hydrophobic fillers. Hydrophilic nanoclay and CNC interacted better with biopolymer matrices than hydrophobic nanoclay, MCC, or CaCO 3 . The load limit of CNC in KGM and HPMC to increase σ of neat polymers was 2% and 4%, respectively. Further addition resulted in γ and σ decrement. Load differences were attributed to differences in microstructure between KGM and HPMC. Addition of CNC up to 50% w/w resulted in a higher iii value of E, suggesting a volume fraction effect of nanocomposite components on films properties. The conclusions of this study were that the addition of nanofillers to biopolymers can lead to reinforced composites if there is good interaction between filler and matrix.Nanocomposite technology offers to broaden the application of biopolymers through the design of new materials with competitive mechanical, thermal, and barrier properties. iv To my parents Idoya Goizueta Iraburu and Jose Resano Lazaro … … and my sisters Lucia, Maria, and Paula. v ACKNOWLEDGMENTS Foremost, I would like to express my most sincere gratitude to Dr. Graciela W. Padua for her guidance, trust, inspiration, and encouragement throughout this study. I greatly appreciate the generous research opportunity and knowledge that she shared with me during these years. I feel very grateful for having such a great advisor!
