Biopolymer Composites in Electronics examines the current state-of-the-art in the electronic application based on biopolymer composites. Covering the synthesis, dispersion of fillers, characterization and fabrication of the composite materials, the book will help materials scientists and engineers address the challenges posed by the increased use of biopolymeric materials in electronic applications. The influence of preparation techniques on the generation of micro, meso, and nanoscale fillers, and the effect of filler size and dispersion on various biopolymers are discussed in detail.

A composite material is a combination of two materials with different physical and chemical properties. When they are combined they create a material which is specialised to do a certain job, for instance to become stronger, lighter or resistant to electricity. They can also improve strength and stiffness. C the first composites were engineered by the Mesopotamians in Iraq. The ancient society glued wood strips on top of each other at different angles to create plywood. Following this, in around B.
Composite Materials pp Cite as. Composite materials are traditionally designed for use as structural materials. With the rapid growth of the electronics industry, composite materials are finding more and more electronic applications. Owing to the vast difference in property requirements between structural composites and electronic composites, the design criteria for these two groups of composites are different. Low density is desirable for both aerospace structures and aerospace electronics. Structural composites emphasize processability into large parts, such as panels, whereas electronic composites emphasize processability into small parts, such as stand-alone films and coatings.
The history of composite materials in manufacturing predates manufacturing as we know it today. From B. From the ancient times, builders, artisans, engineers and manufacturers continued to develop composites of a wider array of materials for more sophisticated applications. In about AD, Mongols invented the first composite bows made from a combination of wood, bamboo, bone, cattle tendons, horns, bamboo and silk bonded with natural pine resin. These small, powerful, extremely accurate bows were the most feared weapons on earth until the 14th century invention of effective firearms. New synthetic resins were transformed from a liquid to solid state in a cross-linked molecular structure using a process known as polymerization.

Applications of soft magnetic composite materials in electrical machines
Metrics details. Soft and conformable electronics are emerging rapidly and is envisioned as the future of next-generation electronic devices where devices can be readily deployed in various environments, such as on-body, on-skin or as a biomedical implant. Modern day electronics require electrical conductors as the fundamental building block for stretchable electronic devices and systems. In this review, we will study the various strategies and methods of designing and fabricating materials which are conductive, stretchable and self-healable, and explore relevant applications such as flexible and stretchable sensors, electrodes and energy harvesters. Stretchable electronic devices have received increasing attention by researchers globally as they have the potential to be applied in many innovative fields such as epidermal electronic devices [ 1 , 2 ], biomedical engineering [ 3 , 4 ], healthcare monitoring [ 5 , 6 , 7 , 8 ], soft robotics [ 9 , 10 , 11 , 12 ], electronic skins [ 13 , 14 , 15 ] and human—machine interfaces [ 16 ].
Engineering Applications of Composite Materials
Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, and motorsports, along with other competition sports. However, they are relatively expensive when compared with similar fibers, such as glass fibers or plastic fibers. To produce a carbon fiber, the carbon atoms are bonded together in crystals that are more or less aligned parallel to the long axis of the fiber as the crystal alignment gives the fiber high strength-to-volume ratio in other words, it is strong for its size. Several thousand carbon fibers are bundled together to form a tow , which may be used by itself or woven into a fabric.

Furthermore, this paper includes ample discussions regarding the advantages and disadvantages resulting in the electrical, mechanical and thermal properties by the addition of micro- and nanofillers into the base polymer. Properties such as electrical conductivity, relative permittivity, dielectric losses, partial discharges, erosion resistance, space charge behavior, electric breakdown, tracking and electrical tree resistance, thermal conductivity, tensile strength and modulus, elongation at break of micro- and nanocomposites based on epoxy resin and XLPE are analyzed. In the last two decades, the design of composite materials comprising either micro-scaled or nano-scaled inorganic particles has gained increased attention in power and high-voltage engineering [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Particularly, the use of micro- and nanotechnologies offers new approaches towards improved insulation systems that operate at higher temperatures and electrical stress. Due to the controlled combination of the components, new materials are obtained with distinct properties from the individual components [ 2 ]. If at least one of the components has nanometric dimensions, these materials are termed nanocomposites [ 3 ]. Thus, nanocomposites are characterized by distinctive advantages including homogenous structure, no fiber rupture, and optical transparency, improved or unchanged processabillity [ 4 ].
Supercapacitor is one of the promising next-generation energy storage devices. Though supercapacitors possess high power capability, their energy densities are still far to be comparable with batteries. Intense research efforts have been attracted in the research of supercapacitors that can yield both high specific power and energy densities. Conducting polymers are one of the spotlight materials for supercapacitors owing to their low-cost, facile synthesis and high capacitance. In this project, we designed and synthesized different polypyrrole PPy -nanosheets based composites for high-performance supercapacitors with enhanced cycle stability. Their electrochemical polymerization process, electrochemical properties and supercapacitor performance were studied with pure PPy film as reference.
