“…[18] A detailed investigation on the enhancement of the mechanical and thermal properties of the biofibers, biofilms, biopolymer, and biocomposites from the renewable and bio-based materials was documented. [19][20][21] Among the bio-based materials, different types of biopolymers, like Chitosan, polysaccharide, polylactic acid, PVA, epoxidized plant oil is mentionable. A few drawbacks, for example, prone to fungi and bacteria, low shelf life, gas permeability, poor mechanical properties and moisture sensitivity were also noticed.…”

Fishbones are hydroxyapatite-based waste materials. They can be used in the form of particles as filler or additive in polymer composites. The surface of the particles can be modified using heat or thermal treatment. In this work, the fishbone particles (FBPs) were used in epoxy composites for the semi-structural applications. The composites were prepared using a solution-cast method. The effect of thermal treatment of the FBPs on the performance of the composites was investigated. The mechanical testing, thermo-gravimetric analysis, and differential scanning calorimetry measured the performance of the composites. The chemical structure and morphological properties of the composites were observed through Fourier transform infrared spectroscopy and scanning electron microscopy, respectively. Results showed that the tensile and flexural strength of the composites were improved by 30% and 200%, respectively, compared to the neat epoxy (NE) as an effect of the thermal treatment. It was also noticed that theT g , T m and T c of the modified composite were found significantly higher compared to other composites. The FBPs formed a hybrid domain within the composites when they interact with the epoxy. Such strong bonding can protect the composites from the external forces. Based on the performance, it can be suggested that the composites can be used where a semi-flexible scaffold is required.

For the creation of tissue-engineered structures based on natural biopolymers with the necessary chemical, physical, adhesive, morphological, and regenerative properties, biocompatible materials based on polysaccharides and proteins are used. This work is devoted to a problem of the technology of polymeric materials for biomedical purposes: the creation of biopolymer tissue engineering matrix and the development of a methodology for studying morphology and functional properties of their surface to establish the prospects for using the material for contact with living objects. The conditions for the formation of scaffolds based on composite materials of chitosan and fibroin determine the structure of the material, the thickness and orientation of molecular layers, the surface morphology, and other parameters that affect cell adhesion and growth. The analysis of studies of the morphology and properties of the surface of biopolymer matrices obtained using different methods of molding from solutions of chitosan and fibroin is carried out.

“…However, these revealed poor hydrophilicity which limits the cell attachment on surfaces and lack of sites for covalent bonding. While having their biodegradable nature, biopolymers or conventional polymers are insulators in nature so that limits the use in some biomedical applications where conducting properties of biomaterials is indispensable (George et al, 2020). In many applications of implants in the body, such as in bone fixing materials, dental materials and bone substitution materials, there is a need for such type of material showing long‐term stable performance.…”

Biomaterials are natural or synthetic materials that are biodegradable and interact cordially with biological systems (Qu et al., 2019). These can be well-defined as a material envisioned to interface with biological systems for evaluation, treatment and replacement of organs, tissues or function of the body (Basu & Ghosh, 2017; Reis et al., 2016). They play a key role in the human health system which is attained from nature or the environment (Mir et al., 2018). Generally, biopolymers are the main class of biomaterials as biopolymers are biocompatible, biodegradable and human body-friendly (Rebelo et al., 2017). These biopolymers are further classified as biodegradable and non-biodegradable according to their nature (Andreeßen & Steinbüchel, 2019; Kabir et al., 2020). Due to their outstanding biocompatibility, biodegradable polymers are known as the best candidate for biomedical applications such as drug delivery systems, vascular grafts, surgical sutures, artificial skin, bone fixation devices, gene delivery systems, tissue engineering and diagnostic applications. Biomedical engineering is an attractive branch which deals with engineering and biology together to put on engineering materials and rudiments in the field of healthcare and medicine. Tissue engineering is also a part of it that fulfils the purposes of recovering or exchange failing or broken body tissue by merging cells, scaffolds and bioactive molecules. Scaffolds should combine various functions such as biodegradability, biocompatibility, ideal mechanical strength, adequate porosity for small molecule transportation, controllability, implantation and sterilization. Hence, natural polymers such as gelatin and chitosan are the perfect match for scaffold fabrication and synthetic aliphatic polyesters too. However, these revealed poor hydrophilicity which limits the cell attachment on surfaces and lack of sites for covalent bonding. While having their biodegradable nature, biopolymers or conventional polymers are insulators in nature so that limits the use in some biomedical applications where conducting properties of biomaterials is indispensable (George et al., 2020). In many applications of implants in the body, such as in bone fixing materials, dental materials and bone substitution materials, there is a need for such type of material showing long-term stable performance. In other applications such as controlled drug delivery, regenerative medicine, tissue engineering
