Novel Nanocellulose/Polymer Composite Aerogel as Solid‐State Fluorescence Probe by Pickering Emulsion Route

Abstract

Aerogels are uniquely porous and environmentally efficient materials with ultralight weight and ultrahigh porosity. [1] Aerogels are prepared by removing the liquid dispersion medium from the gel without collapsing the network structure. [2] Various types of aerogels can be fabricated from carbon nanofiber, [3,4] carbon nanotube, [5] graphene, [6] silica, [7,8] and

Recent development of plant-derived nanocellulose in polymer nanocomposite foams and multifunctional applications: A mini-review

“…The good dispersion of hydrophilic nanocellulose particles in hydrophobic polymer matrices could be successfully achieved by the Pickering emulsion approach without any chemical modification [89,91,92]. The Pickering emulsion process has been proved to be a straightforward way to fabricate nanocomposite foams with organized nano or microstructures [93][94][95]. Nanocellulose particles acting as an emulsifier at the oil-water or air-water interface to stabilize emulsions could control porosity, pore size and mechanical properties of the foams [95][96][97].…”

“…Nanocellulose particles acting as an emulsifier at the oil-water or air-water interface to stabilize emulsions could control porosity, pore size and mechanical properties of the foams [95][96][97]. Recent works on the use of CNFs to stabilize nonwater-soluble polymer droplets such as poly(carbonate) (PC), poly(methyl methacrylate) (PMMA), polystyrene (PS), and PLA have been reported [93]. Nonwatersoluble polymers dissolved in 1,2-dichlorothane (DCE) to form the oil phase were stabilized by CNFs through the Pickering emulsion pathway, and the emulsion was lyophilized to develop a nanocomposite foam.…”

Inherently Distinctive Potentialities and Uses of Nanocellulose Based on its Nanoarchitecture

“…The amphiphilic features of nanocellulose-which has spatially separated hydrophilic and hydrophobic crystalline faces-facilitate the formation of micro-and nanoparticles via Pickering emulsion systems (Fujisawa et al 2017a). Such "Janus" structures have prompted the development of high-performance nanocomposites (Fujisawa et al 2017b), functional aerogels (Li et al 2020b), and thermal storage materials (Chakrabarty and Teramoto 2020). Ultrastable Pickering emulsions can be designed by tuning the sources, shapes, and surface charges of nanocellulose (Saelices and Capron 2018).…”

Fabrication of Cellulose Nanofiber/Reduced Graphene Oxide/Nitrile Rubber Flexible Films Using Pickering Emulsion Technology for Electromagnetic Interference Shielding and Piezoresistive Sensor

“…Pickering emulsion is an emulsion stabilized by solid particles instead of organic surfactants. Recently, Pickering emulsion has been increasingly attracting attention in the design and construction of unique structural and functional materials, such as magnetic or biocompatible microcapsules, [32] microspheres, [33][34][35] aerogels as a solid-state fluorescent probe, [35,36] solar water evaporators, [36,37] microwave absorption materials, [38] and so on. More interestingly, cellulose nanofibrils (CNF) stabilized Pickering emulsion has been used to prepare a transparent and strong polymer matrix composite with unique self-assembled two-tier hierarchy CNF networks, according to our previous study.…”
