“…Thus, the use of cationic surfactants as an additive proves to be an effective strategy for reducing beads, improving those properties and also reducing fiber diameters ( Abutaleb et al, 2017 ; de Almeida et al, 2020 ; Lin et al, 2004 ; Wang et al, 2010 ). Besides, it can attribute biocide characteristics to the nanofibers, such us, the cationic surfactant cetylpyridinium bromide (CPB) that is an antibacterial agent widely used in the pharmaceutical industry ( Cole et al, 2011 ; Lukáč et al, 2013 ; Malek and Ramli, 2015 ; Wu et al, 2020 ).…”

“…The peak at 283.9 eV corresponds to the binding energy of the C-N bond, and the peaks of C=O and C-C mainly appear at about 286.8 eV and 285.0 eV. (Wu et al 2020). Compared with other components, the C1 s of CS-MMT2 is significantly enhanced, and the intensity of the C-N peak is also significantly increased, proving that MMT was successfully modified by CS.…”

The modified montmorillonite(MMT) has a two-dimensional stable and ordered lamellar structure. The addition of chitosan(CS) cross-links the two-dimensional sheets to build a three-dimensional network structure with a high specific surface area. We have prepared the best MMT-based water treatment materials that have been reported. This new type of aerogel can efficiently adsorb heavy metal ions in wastewater. The structure and performance of the composite material were characterized in this article. Besides, the adsorption kinetics, adsorption thermodynamics, pH influence, and recycling performance are all focused on. The adsorption equilibrium time of CS-MMT2 is 50 min. The removal rate of Cu2+ is as high as 98.21%. The maximum adsorption capacity is 86.95 mg/g. The adsorption process of Cu2+ by CS-MMT composite aerogel conforms to the quasi-second-order kinetic model and the Langrangian adsorption isotherm. After three cycles, the removal rate of Cu2+ by CS-MMT2 remained above 80%. This article also involves the discussion of the material's adsorption mechanism for Cu2+. This is a kind of environmentally friendly material that can be mass-produced, cheap, efficient, and excellent, which is of great significance to the development of environmental protection.

“…In this way, the bead formation specific to CA nanofibers is diminished [ 43 , 44 , 45 , 46 , 47 ]. Most of these cationic surfactants, such as cetylpyridinium bromide (CPB), expose biocide properties and lead to nanofiber applications in the pharmaceutical industry [ 48 , 49 , 50 , 51 ] and in filtering airborne nanoparticles [ 43 ].…”

The aim of this review is to bring together the main natural polymer applications for environmental remediation, as a class of nexus materials with advanced properties that offer the opportunity of integration in single or simultaneous decontamination processes. By identifying the main natural polymers derived from agro-industrial sources or monomers converted by biotechnology into sustainable polymers, the paper offers the main performances identified in the literature for: (i) the treatment of water contaminated with heavy metals and emerging pollutants such as dyes and organics, (ii) the decontamination and remediation of soils, and (iii) the reduction in the number of suspended solids of a particulate matter (PM) type in the atmosphere. Because nanotechnology offers new horizons in materials science, nanocomposite tunable polymers are also studied and presented as promising materials in the context of developing sustainable and integrated products in society to ensure quality of life. As a class of future smart materials, the natural polymers and their nanocomposites are obtained from renewable resources, which are inexpensive materials with high surface area, porosity, and high adsorption properties due to their various functional groups. The information gathered in this review paper is based on the publications in the field from the last two decades. The future perspectives of these fascinating materials should take into account the scale-up, the toxicity of nanoparticles, and the competition with food production, as well as the environmental regulations.
