“…Because of the chemically and thermal stability of PVA, it is resistant to degrade in most physiological environments and the introduction of CMC (in which -CH2COOH group is bound to some -OH group of natural cellulose) to PVA results in the improvement of its biodegradable properties 29 Young's Modulus (MPa) ). The samples were removed after every 4 days, washed carefully, dried and finally weighted.…”

Carrot (Daucus Carota L.) fiber consists of cellulosic substances and can be used to make biodegradable and economical packaging films. Biofilms of Polyvinyl alcohol (PVA) and Carboxymethyl cellulose-Na salt (CMC) with Carrot fiber (CF) have been synthesized by solution casting technique. Polyethylene glycol (PEG) is used as a plasticizer for a sustainable reaction medium. FTIR, UV-Visible, thermal analysis, SEM and tensile testing techniques have been used to analyze the films. The thermal decomposition of biofilms was studied by a thermogravimetric analyzer in a nitrogen atmosphere at a heating rate of 10 °C min -1 from ambient temperature to 600 °C. Kinetic parameters were calculated using kinetic methods viz. Broido, Coats-Redfern and Horowitz-Metzger. FTIR spectra give out the results for significant peak changes and are backed by UV-spectra to compare the optical properties of composites with neat PVA. Young's Modulus (MPa) and Tensile strength (MPa) values decrease with fiber addition to PVA/CMC. An optimal value of 12.5 wt % loading was obtained concerning tensile as well as thermal analysis data. Biodegradation studies were also performed in soil and compost. Route of degradation has been proposed based on spectral studies. It is concluded that the incorporation of carrot fibers in composites enhanced the degradation of PVA just like CMC and resulted in films with enhanced UV protection properties.

“…Currently, the average life expectancy in the world is more than 73 years; according to the United Nations Organization (UNO) data, approximately more than 950 million humans are above 60 years old, and by the end of the 21 st century, that number will be tripled [36,37]. The search for enhancements in life expectancy and quality has made it feasible for the modern community to observe scientific and technological advancements in several sciences during recent years [38,39]. The first advances took place at the start of the 20 th century by synthesizing the first vanadium steel alloys for fracture fixation or threads capable of being degraded and absorbed with the human body [40].…”

“…Also, scCO 2 reduces the glass transition temperature and, the viscosity of the various polymers and Tg without differently altering their pseudo-plastic behavior [129]. Another benefit of using scCO 2 extrusion techniques is modifying the rheological characteristics of the compound inside the extruder, which also performs the role of an expansion factor [38]. The reduction of vis- cosity will appear in the limitation of shear and mechanical stresses and provide a decrease in mixture temperatures.…”

Tissue engineering (TE) employs biological, chemical, and engineering methods to regenerate and restore injured or lost living tissues by applying biologically activated biomaterials, cells, and molecules. The fast and convenient restoration of tissue is a great challenge, emphasizing the need to imitate tissue structure and its physicochemical, biological, and mechanical behavior to give back the desired functionality of damaged tissue. Depending on the particular tissue, numerous requirements have to be fulfilled with the help of material and scaffold design that provides a base for cell adhesion and proliferation. As a result, countless biodegradable and bioresorbable materials have been extensively examined. Composite systems combine the benefits of bioactive ceramics and polymers, which seem to be good alternatives for bone tissue engineering. This article intends to introduce bioactive polymer, tissue engineering methods, the kinds of biomaterials applied in scaffold invention, and the different approaches to producing the bioactive polymer-based composites with various structures such as porous, membrane, and 3D structure. Biomaterials and invention techniques could crucially influence the consequences of the scaffold's design architectures, cell proliferation, and mechanical behavior. Moreover, an excellent scaffold assists cell generation and the provision of cell nutrients in the human body with their particular material characteristics.

Wearable electronics are gaining widespread attention because of the potential applications of them in systems of wearable human care and health monitoring. These new devices are probably a collection of different applications like batteries, sensors, displays, and so on. In these respects, conductive fibers, inks, and fabrics were examined. On the field, three materials categories including carbon, metal, and polymer-based materials were investigated. Materials of carbon have advantages like good electrical conductivity, structural and inherent flexibility, high thermal and chemical stability, light weight, ease of chemical operation, and potential production of mass, enabling them to be a good candidate for wearable and flexible electronics. Conducting polymers have a number of drawbacks in their natural state; however, by combining them with other materials, these drawbacks can be solved. Conducting polymer composites have a wide range of applications in optoelectronic, electronic, and electrical sectors due to their synergetic effects. Liquid metal was bestowed with new-emerging characteristics and multifunctional applications. Due to the high surface tension and limited adherence on many surfaces, the manufacturing approach of patterning liquid metals on flexible substrates has received a lot of attention up to now.The current state of wearable materials as actuators and fabrication processes are discussed in this review paper.
