“…In addition to silicates, several different inorganic solids have been added as reinforcements to biopolymer materials; for example, the distribution of sepiolite in natural rubber causes improvement in mechanical properties [27]. Tensile strength and elastic modulus of natural rubber are increased by the addition of single walled carbon nanotubes (SWCNTs) and SiC nanoparticles-based reinforcements, have become improved that those with just SWCNTs-based materials [28]. Multiwalled carbon nanotubes (MWCNTs) dispersion in natural rubber materials also represented a similar effect, for example, improved physical, mechanical, and chemical properties of biopolymer [29,30] as presented in Figure 3.…”

This chapter presents a broad overview of the current advancements in bioplastics and bioinspired nanocomposites with nanoscale reinforcements that are being applied for a broad range of applications, that is, biomedical, electronics, durable goods and packaging materials. The production of nanocomposites by completely and/or partially renewable and biodegradable materials has helped in a range of different applications. Several drawbacks of conventional materials such as hydrophilicity, low-heat deflection, poor conductivity, and barrier properties can be efficiently overcome using biohybrid nanomaterials. Nano-reinforcements in composite materials deliver remarkably improved properties such as decrease in hydrophilicity and increase in mechanical properties as compared with neat biopolymer, which fails to exhibit these properties on its own. This approach can be used for other natural polymers to induce desired functionalities. This chapter covers the recent trends in nano-functional materials, renewable materials that are being applied for the production of nanobiocomposites and their applications especially in biomedical and healthcare sectors, which are discussed in detail. This emerging concept will definitely enhance the scope of nanohybrid materials for sustainable products development with improved properties than previously applied synthetic polymer-based or natural polymer-based materials.

Highly dense yttria-stabilized zirconia (YSZ) nano-ceramics reinforced with TC-CVD-synthesized multiwall carbon nanotubes (MWCNTs) were fabricated using spark plasma sintering at a temperature of 1350°C, the heating rate of 100 °C/min and pressure of 50MPa with a dwell time of 10 minutes. The identical parameters were utilized for fabricating composites with a varying weight ratio of YSZ and MWNCTs. The samples were characterized for their phase transformation, microstructure and elemental composition using x-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The physical and mechanical properties such as density, porosity, hardness, fracture toughness and wear were also investigated. The increase in the MWCNTs concentration has resulted in the deterioration of the hardness due to CNT agglomerations. The wear resistance of the composites revealed MWNCTs enhanced wear resistance of YSZ nanocomposite by undergoing MWNCTs pull-out and crack branching mechanisms. Further indentation method and single-beam V-notch beam (SEVNB) methods were utilized to study the effect of MWCNTs on the fracture toughness of the nanocomposites. The fracture toughness of YC1 (6.58 ± 0.3 MPa m1/2) was 21% higher than the YSZ (5.21 ± 0.2 MPa m1/2) due to the toughening mechanisms attributable to crack deflection, branching and bridging of MWCNTs.
