Bionanocomposites

Polymer composite materials are consistently being used in various industrial and domestic applications due to their lightweight, high-specific strength, and low cost. In order to enhance various performance of polymer composites, a suitable nanofiller can be used. Polymer composites, which take advantage of natural fibers and nanofillers, synergistically, contribute to improved properties and environmental condition by making them suitable for various applications (aerospace, automobile industries, electronics, biomedical, etc.). The present study gives an insight of nanofiller-based polymer composite and the challenges associated with processing methods. The use of nanofillers in polymer composites to enhance their mechanical properties (tensile, flexural, impact, and tribological) and most importantly the self-healing property due to which they are finding numerous applications. This study also includes the problems associated with excessive use of nanomaterial leading to various environmental and health hazards. The problems and their remedies associated with nano-toxicity have also been addressed.

“…Thus, biopolymer-based nanocomposites can be a sustainable alternative for petroleum-based nanocomposites in many applications due to their biodegradability, eco-friendliness, renewability, relatively inexpensive, low toxicity, abundancy, and improved thermal, mechanical, physical, barrier, and functional properties [ 3 , 4 ]. Various natural biopolymers, including starch, cellulose, pectin, lignin, chitin/chitosan, alginates, hyaluronic acid, gelatin, terpenes, gelatin, gluten, and polyhydroxyalkanoates (PHAs) from plants, animals, algae, microorganisms and synthetic biopolymers, including polycaprolactone (PCL), poly(butylene succinate) (PBS), poly(lactic-co-glycolic acids) (PLGA), and polylactic acids (PLA), have been used in nanocomposite materials for various applications [ 1 , 2 , 3 , 6 , 7 , 8 ].…”

In recent years, the demand for environmental sustainability has caused a great interest in finding novel polymer materials from natural resources that are both biodegradable and eco-friendly. Natural biodegradable polymers can displace the usage of petroleum-based synthetic polymers due to their renewability, low toxicity, low costs, biocompatibility, and biodegradability. The development of novel starch-based bionanocomposites with improved properties has drawn specific attention recently in many applications, including food, agriculture, packaging, environmental remediation, textile, cosmetic, pharmaceutical, and biomedical fields. This paper discusses starch-based nanocomposites, mainly with nanocellulose, chitin nanoparticles, nanoclay, and carbon-based materials, and their applications in the agriculture, packaging, biomedical, and environment fields. This paper also focused on the lifecycle analysis and degradation of various starch-based nanocomposites.

“…Electrospinning attracts great attention for fabrication of micro/nano fibrous materials similar to human tissues [ 124 , 125 ] due to its simplicity and the good characteristics of the derived scaffolds (e.g., high porosity, high surface area to volume ratio). Although within this technique it is possible to provide bone, skin, nerve, and cardiac tissues, it should be indicated as a major challenge the difficulty to find a suitable solvent to sufficiently evaporate and stabilize the spinning process [ 126 ]. However, electrospinning of natural polymers like collagen, chitosan, and gelatine make this technique to surpass others to accurately mimic natural ECMs [ 28 ].…”

Tissue engineering approaches appear nowadays highly promising for the regeneration of injured/diseased tissues. Biomimetic scaffolds are continuously been developed to act as structural support for cell growth and proliferation as well as for the delivery of cells able to be differentiated, and also of bioactive molecules like growth factors and even signaling cues. The current research concerns materials employed to develop biological scaffolds with improved features as well as complex preparation techniques. In this work, hybrid systems based on natural polymers are discussed and the efforts focused to provide new polymers able to mimic proteins and DNA are extensively explained. Progress on the scaffold fabrication technique is mentioned, those processes based on solution and melt electrospinning or even on their combination being mainly discussed. Selection of the appropriate hybrid technology becomes vital to get optimal architecture to reasonably accomplish the final applications. Representative examples of the recent possibilities on tissue regeneration are finally given.
