“…Advanced composites majorly of biodegradable sources are considered as a better alternative to conventional materials due to their significant enhancement in mechanical, structural, and tribological properties [8,[14][15][16]. Natural fibers when used as reinforcements particularly in the nanometer range have been found to drastically improve the properties of the materials such as the strength, stiffness, fracture toughness, thermal stability, electrical conductivity, and wear resistance of materials making them highly suitable for application in diverse fields like construction, automobile, biomedical, marine, aerospace, and military [17]. For example, Singha and Thakur [18] synthesized natural fibers of Hibiscus Sabdariffa with phenol-formaldehyde resin matrix to form a polymer composite to analyze the tensile strength, compressive strength, flexural strength, and wear resistance properties of the material.…”

Right from the early days, polymer materials have been discovered as being beneficial for various applications but a poor understanding of these materials greatly handicapped their usage. However, with a change in this trend, polymer materials have gradually displaced other materials in most applications. In recent times, due to improved research and knowledge, polymer-based materials are the first choice materials for several applications and are now replacing other materials rapidly. More advanced materials from polymers are being developed daily as a substitute for other materials even in areas where polymers are considered not to be suitable in the time past. More recently, polymers have replaced metals and ceramics in applications like constructions, aerospace, automobiles, and medical. It is no doubt that this trend will continue due to the inherent properties of polymers and sustainability potential. Today, most of the limitations of polymers are being taken care of in the formulation of composite materials. Besides, the adaptation to positive environmental influence is being handled by scientists and researchers. Hence, this review reveals core areas of application of polymer-based composites and the significance of these materials to the advancement of humanity.

Diseases and injuries of the musculoskeletal system rank second among the causes of injuries and third among the diseases that lead to disability of the adult population. Orthopedic implants have a special place in both clinical practice and the biomedical industry. The implants capable of biodegrading in the case of their implantation into the human body are of the greatest interest. The concept of biodegra-dable implants appeared through the formation and development of the use of suture materials that are absorbed in the body. Subsequently, this type of material began to be used in the treatment of fractures, because in many cases, bone fragments need only temporary support with a fixator, until they fuse. Implantable internal fixation devices for fracture repair using polyglycolic acid (PGA), polylactic acid (PLA), and a copolymer of lactic acid and glycolide (PLGA) became popular. However, the mechanical properties of highly porous skeletons were relatively weak compared to those required for bone engineering. In the process of creating an optimal polymeric biodegradable material, it is necessary to overcome the contradiction between strength and biodegradation. PGA, providing high strength of fixation, degrade too quickly, and PLGA, having high crystallinity, slightly degrade, at the same time conceding on the durability of both PGA and biostable materials. Scientists are now working hard to develop composites from calcium phosphate and polymer, in particular hydroxyapatite and tricalсium phosphate (TCP). TCP with three polymorphic modifications, in particular α-TCP, β-TCP, and α'-TCP, is a well-known bioceramic substance for bone repair. β-TKP is attracting increasing attention due to its excellent biocompatibility, bioactivity, and biodegradability. The composite materials based on bioactive ceramics mainly refer to materials with additional advantages, such as biodegradable polymers and ceramics. At the same time, these composites are biocompatible, osteoconductive, mechanical strength and have osteogenic characteristics. At the same time, thanks to new manufacturing technologies that have emerged in recent years, these compo-site materials are the most promising in the field of bone defect repair. The treatment of fractures with implants is increasingly associated with composite materials. Biomaterials must have certain mechanical properties: biocompatibility, biodegradation, controlled rate biodegradation, good mechanical strength, and bioactivity. Biomaterials used in the treatment of bone fractures have to disintegrate over time, and the addition of nanofillers can slow down the rate of decay of the biodegradable composite.

“…Nowadays, the creation of multifunctional materials represents a real challenge since it is aimed at overcoming the criticalities connected with the use of composite materials in the aeronautical field [ 1 , 2 , 3 , 4 , 5 , 6 ], such as reduced electrical properties and poor damage resistance. In fact, the principal hazard associated with the use of composites is determined by the generation of micro-cracks inside the structure which are difficult to identify and repair and which can, consequently, cause catastrophic damage.…”

A big step forward for composite application in the sector of structural materials is given by the use of Multi-Wall Carbon Nanotubes (MWCNTs) functionalized with hydrogen bonding moieties, such as barbiturate and thymine, to activate self-healing mechanisms and integrate additional functionalities. These materials with multiple healing properties at the same damaged site, imparted by hydrogen bonds, will also have the potential to improve material reliability, extend the service life, reduce replacement costs, and improve product safety. This revolutionary approach is obtained by integrating the non-covalent interactions coupled with the conventional covalent approach used to cross-link the polymer. The objective of this work is to characterize rubber-toughened supramolecular self-healing epoxy formulations based on unfunctionalized and functionalized MWCNTs using Tunneling Atomic Force Microscopy (TUNA). This advanced technique clearly shows the effect produced by the hydrogen bonding moieties acting as reversible healing elements by their simultaneous donor and acceptor character, and covalently linked to MWCNTs to originate self-healing nanocomposites. In particular, TUNA proved to be very effective for the morphology study of both the unfunctionalized and functionalized carbon nanotube-based conductive networks, thus providing useful insights aimed at understanding the influence of the intrinsic nature of the nanocharge on the final properties of the multifunctional composites.
