“…After gelation is achieved, the gel is then dried either through freeze drying or supercritical drying [72]. Many studies have utilized this method to produce nanocellulose aerogels for applications such as food packaging, thermal insulation, catalyst systems, shape memory aerogels, drug release, tissue engineering, and supercapacitors [77,81,85,86,87,88,89].…”

Aerogels are one of the most interesting materials of the 21st century owing to their high porosity, low density, and large available surface area. Historically, aerogels have been used for highly efficient insulation and niche applications, such as interstellar particle capture. Recently, aerogels have made their way into the composite universe. By coupling nanomaterial with a variety of matrix materials, lightweight, high-performance composite aerogels have been developed for applications ranging from lithium-ion batteries to tissue engineering materials. In this paper, the current status of aerogel composites based on nanomaterials is reviewed and their application in environmental remediation, energy storage, controlled drug delivery, tissue engineering, and biosensing are discussed.

Nanocelluloses (NCs) have remarkable mechanical properties and contain abundant surface functional groups that can be modified or cross‐linked with other materials. They have been widely used as an environment‐friendly reinforcing agent in polymer composites. However, for applications that are carried out in humid environments or aqueous suspensions, hydrophilicity of NCs lower their mechanical integrity. Hence, cross‐linking techniques have been investigated in recent years for preparing NC‐based materials that are dimensionally stable under humid or aqueous environments and have better physicochemical properties. This Minireview examines the quickly growing field of cross‐linked NC‐based materials, which have many benefits including improved aqueous, structural, mechanical, and thermal stability. In addition, the potential application of cross‐linked NC‐based materials in adsorption of heavy metal is discussed.

“…The aerogels were found to be stable even after over 80 cycles of spontaneous compression–relaxation of gel, exhibiting excellent wet strength and reusability. The maximum adsorption capacity was reached to 175.44 mg g −1 and 357.14 mg g −1 for Cu(II) and Pb(II), respectively . The effect of deacetylation on the property of electrospun chitosan/polyvinyl alcohol nanofibers and removal efficiency of iron and chromium was investigated by Habiba and coworkers.…”

Studies involving bio‐based nanofibers are well utilized in the field of energy, catalysis, electronics, and environmental science. In this review, the importance of utilizing bio‐based materials for the development and optimization of multiplexed nanofibers and the modifications adopted to overcome the drawbacks of conventional electro‐spinning to facilitate better production rates, enhanced adsorption, and its potential in removing heavy metal ions, dyes, and other contaminants polluting the environment are highlighted. This work provides the readers the ability to understand the complexity in fabrication of bio‐based nanofibers focusing primarily on chitosan, cellulose, and protein‐based nanofibers and their mechanism toward quenching/degradation of water contaminants. In addition, it also provides the advantages of using bio‐based materials over synthetic materials for the development of nanofibers.
