“…To analyze the Li‐dendrite‐formation process on common carboneous materials, we used commercial carbon cloth as the substrate. Both D and G bands in the Raman spectrum (Figure S1A, Supporting Information) and broad peaks in the X‐ray diffraction (XRD) data (Figure S1B, Supporting Information) suggest that the carbon cloth has a hybrid texture of layer‐structured graphite and unorganized carbon . In consequence, the Li deposition process of a more disordered carbon can be characterized into two processes, e.g., the intercalation into the layer structure and the insertion into the unorganized carbon.…”

Lithium metal has attracted much research interest as a possible anode material for high-energy-density lithium-ion batteries in recent years. However, its practical use is severely limited by uncontrollable deposition, volume expansion, and dendrite formation. Here, a metastable state of Li, Li cluster, that forms between LiC and Li dendrites when over-lithiating carbon cloth (CC) is discovered. The Li clusters with sizes in the micrometer and submicrometer scale own outstanding electrochemical reversibility between Li and Li, allowing the CC/Li clusters composite anode to demonstrate a high first-cycle coulombic efficiency (CE) of 94.5% ± 1.0% and a stable CE of 99.9% for 160 cycles, which is exceptional for a carbon/lithium composite anode. The CC/Li clusters composite anode shows a high capacity of 3 mAh cm contributed by both Li intercalation and Li-cluster formation, and excellent cycling stability with a signature sloping voltage profile. Furthermore, the CC/Li clusters composite anode can be assembled into full cells without precycling or prelithiation. The full cells containing bare CC as the anode and excessive LiCoO as the cathode exhibit high specific capacity and good cyclic stability in 200 cycles, stressing the advantage of controlled formation of Li clusters.

“…Besides these nanomaterials, graphene is another nanomaterial of significant importance because of its antimicrobial property and superior mechanical strength [9]. Reduced graphene oxide-based nanomaterials have been used for fabrication of antimicrobial and superhydrophobic coatings with excellent mechanical strength and corrosion resistance property [10][11][12][13]. It is worthy to note that superhydrophobic and antimicrobial surfaces have found applications in medical textiles [14], military clothing [2], anti-biofouling coatings on surgical appliances and biodevices [15].…”

Now-a-days, it is obvious that nanomaterials can play significant role in every sphere of our modern lives. On this aspect, use of nanomaterials in developing advanced functional materials or towards enhancement in surface related physical properties including superhydrophobic or superhydrophilic properties is very important both in fundamental and applied research. In this regard, most of the researchers agreed that there is a close relationship between superhydrophobicity of material surface with its antimicrobial activity. This review briefly highlights the use of some inorganic/organic based nanomaterials such as Ag, Cu, ZnO, TiO 2 as inorganic materials and graphene, chitosan nanoparticles as organic materials in making superhydrophobic antimicrobial coatings. Based on reported literature, possible mechanisms of antimicrobial activity of the nanomaterials derived superhydrophobic coatings have been discussed. It is worthy to note that the coatings with the advancement in self-cleaning and anti-biofouling as well as superhydrophobic and antimicrobial properties are highly potential for enormous applications in biomedical fields including medical textiles, personal protective equipment (PPE), surgical appliances, biodevices and so on. In this review, the challenges and future prospect of the nanomaterials based superhydrophobic coatings have also been discussed briefly. This mini review may encourage researchers towards development of superhydrophobic and antimicrobial coatings on various substrates like plastics, glasses, cotton fabrics for making PPE to protect the dedicated medical / healthcare personnel from the currently pandemic COVID-19 disease caused by severe acute respiratory syndrome coronavirus 2.

“…Another study showed that PANi coated magnetic nanocomposite was capable of removal of chromium, as well as reduction of hexavalent to trivalent state . Recently, graphene and graphene oxide (GO) have attracted tremendous interest due to their special 2D nanostructures and fascinating properties . The decoration or functionalization onto graphene nanosheets facilitate the decrease of the aggregation of graphene nanosheets and guarantee the large specific surface area.…”

Facile Assembly of Polyaniline/Graphene Oxide Composite Hydrogels as Adsorbent for Cr(VI) Removal

A facile method for the assembly of polyaniline/graphene oxide (PANi/GO) composite hydrogel has been successfully demonstrated by in‐situ polymerization of aniline in the presence of phytic acid with the aid of GO. During the polymerization of aniline, the 2D GO nanosheets can regulate the aggregation state of polymer and prompt the formation of the hydrogel. The chemical structure, morphology and mechanical property are investigated by Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscopy and compressive stress–strain measurements, et al. Pani/GO composite hydrogel with high surface area and 3D porous nanostructures exhibits higher adsorption capability for Cr(VI) in compared with PANi hydrogel. Pseudo‐second‐order and Langmuir isotherm models are effectively employed to describe the adsorption behaviors of PANi/GO composite hydrogel. Furthermore, the regeneration experiments indicate that the as‐prepared composite hydrogel can remain 73.5% of the original removal capability after five adsorption–desorption cycles. It is expected that the PANi/GO composite hydrogel can be an effective candidate for the removal of Cr(VI) due to the synergistic effects between PANi and GO within the hydrogel network. POLYM.
