Recent progress on nanostructured conducting polymers and composites: synthesis, application and future aspects

Conducting polymers (CPs) have been widely investigated due to their extraordinary advantages over the traditional materials, including wide and tunable electrical conductivity, facile production approach, high mechanical stability, light weight, low cost and ease in material processing. Compared with bulk CPs, nanostructured CPs possess higher electrical conductivity, larger surface area, superior electrochemical activity, which make them suitable for various applications. Hybridization of CPs with other nanomaterials has obtained promising functional nanocomposites and achieved improved performance in different areas, such as energy storage, sensors, energy harvesting and protection applications. In this review, recent progress on nanostructured CPs and their composites is summarized from research all over the world in more than 400 references, especially from the last three years. The relevant synthesizing experiences are outlined and abundant application examples are illustrated. The approaches of production of nanostructured CPs are discussed and the efficacy and benefits of newest trends for the preparation of multifunctional nanomaterials/nanocomposites are presented. Mechanism of their electrical conductivity and the ways to tailor their properties are investigated. The remaining challenges in developing better CPs based nanomaterials are also elaborated.

Organic-templated silica membranes: I. Gas and vapor transport properties

A novel and efficient method for molecular engineering of the pore size and porosity of microporous sol-gel silica membranes is demonstrated in this communication. By adding a suitable organic template (e.g. tetraethyl- or tetrapropylammonium bromide) in polymeric silica sols, otherwise known to result in microporous membranes with pores in the range 3-4A, we can ‘shift’ the pore size to 5-6A, as judged by single-component gas and vapor permeation results with probe molecules of increasing kinetic diameter (dk). The templated membranes exhibit permeances as high as 10-7 to 10-6molm-2s-1Pa-1 for molecules with dk<4.0A (e.g. CO2, N2, CH4), coupled with single-component selectivities of 100-1800 for N2/SF6, 20-40 for n-butane/iso-butane, and 10-20 for para-xylene/ortho-xylene. The transport properties of the templated membranes are distinctly different from those of the respective silica membranes prepared without templating, and resemble somewhat the transport properties of polycrystalline zeolite MFI membranes prepared by the lengthy, batch hydrothermal synthesis approach, using tetrapropylammonium bromide as a structure directing agent. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Novel cationic amphiphiles

A cationic amphiphile for facilitating transport of a biologically active molecule into a cell has the structure A-F-D, in which A is a lipid anchor, D is a head group, and F is a spacer group having the structure described herein. A method for facilitating transport of a biologically active molecule into a cell comprises preparing a lipid mixture comprising a cationic amphiphile having structure A-F-D, preparing a lipoplex by contacting the lipid mixture with a biologically active molecule; and contacting the lipoplex with a cell, thereby facilitating transport of the biologically active molecule into the cell.

Mxene functionalized polymer composites: Synthesis and applications

Ever since their inception, Mxene have been gathering immense attention due to their exceptional and functional properties owing to their large surface areas and electronic properties. Mxene are derived from MAX phase by exfoliating them into 2D layers of transition-metal carbide and nitrides, using hydrofluoric acid (HF) solutions and sonication. Although the applications of Mxene are limited, numerous composites of Mxene filled with potential scientific and technological applications are being synthesized around the world. Several composites of Mxene like carbon nanotubes, graphene oxide etc. have been studied over the years for high capacity energy storage but these composites sometimes lack various structural and biological properties which steers research towards more flexible solutions, literally and figuratively. Polymers are a great choice for synthesizing composites of Mxene due to their versatility, compatibility and cost. As wearable technology gains popularity, MXene coated polymers emerged as a solution, delivering exceptional flexibility, mechanical and tensile strength in the form of flexible super capacitors. Focussing on the polymer composites of Mxene, this review provides a comprehensive categorical view based on application on the various polymer composites synthesized till date highlighting their promising potential in various fields of science with a vision of their future applications.

The reaction of the organodilithium reagent (tmen = Me2NCH2CH2NMe2) and the appropriate metallocene(IV) chloride in OEt2 at ca. 35 deg C yields the corresponding crystalline, thermally stable, stereospecifically pure meso-metallindane ; by-products in two of these reactions are <(Ti(eta-C5H5)2Cl)2> or the binuclear zirconium compound (6) formulated as meso-.Compounds (2)-(5) are sublimable at ca. 140 deg C (10-3 Torr), and on pyrolysis afford o-C6H4(CH2SiMe3)2; they are reasonably air-stable and inert to CO under ambient conditions.Compound (6) is also accessible from (3) in OEt2 and successively Li(tmen)Bun in n-C6H14 and .Assignment of the meso (rather than rac) diastereomeric configuration for complexes (2)-(4) rests on their n.m.r. spectra and for (3) on X-Ray data.E.s.r. data on complex (5), or the Na(C10H8)-tetrahydrofuran reduction products of each of (2)-(4), are consistent with each being a d1 complex.The electrochemical reduction <-E<*>red = 1.46 (Ti), 2.02 (Zr), or 2.26 V (Hf)> of each of the complexes (2)-(4) is pseudo-reversible, but the anions tend to lose C5H6-.The niobium complex (5) undergoes reversible one-electron oxidation (E<*>ox = -0.47 V) or reduction (-E<*>red = 1.63 V).The X-ray structure of the title metallaindane (3) shows pseudo-tetrahedral co-ordination of Zr with a centroid-Zr-centroid’ angle of 125.1 deg and bite angle Calpha-Zr-Calpha’ of 80.2(2) deg, with 2.305(4) and Cbeta,Cbeta’> 2.71(1) Angstroem; hence the o-C6H42-metal bonding is best described as intermediate between that appropriate for metalla(IV)cyclic and an eta4-5,6-dimethylenecyclohexa-1,3-diene-metal(II) structure; consistent also is the fold angle, Phi, of 66.7 deg (Phi being thedral angle between the ZrCalphaCalpha’ plane and and the C8 extension of the aromatic plane).
