One-pot facile simultaneous in situ synthesis of conductive Ag–polyaniline composites using Keggin and Preyssler-type phosphotungstates

Abstract

Two heteropolytungstate structures, (a) Keggin (H3PW12O40) and (b) Preyssler (H14(NaP5W30O110]), have been used to synthesize conductive silver nanoparticle–polyaniline–heteropolytungstate, (AgNPs–PAni–HPW) nanocomposites.

Polymer-based wafers containing in situ synthesized gold nanoparticles as a potential wound-dressing material

“…Furthermore, accordingly to the IUPAC classification, the produced wafers exhibited a hysteresis loop with a H3 type [45]. This hysteresis loop typically consisted of slit-shaped pores [46], corroborating the SEM images. The (56.11 m 2 /g).…”

Synthesis and Structural Characterization of Multi‐Molybdenum‐Substituted Preyssler‐type Phosphotungstates

“…The POM family exhibits properties such as multi-electron redox activity, acidic property, photochemistry, and magnetism, and has been applied in many fields of functional materials, such as catalysts, conducting materials, and magnetic materials. [1,2] Among the wide class of POMs, Preyssler-type phosphotungstates have been attracting significant attention, and they have been applied as catalysts, [3][4][5][6][7][8][9][10][11][12] single-molecule electret materials, [13] single-molecule magnetic materials, [14] conductive materials, [15][16][17][18][19][20][21][22][23] staining reagents, [24] antitumor activity, [25] liposome collapse reagents, [26] and antibacterial agents. [27][28][29][30] The Preyssler-type phosphotungstates, [P 5 W 30 O 110 Z n + (H 2 O)] (15À n)À , are constructed using five PO 4 tetrahedra surrounded by thirty WO 6 octahedra, which create a doughnut-shaped structure with an internal cavity space that can encapsulate a cation (Z n + ) in the molecule (Figure 1).…”

One-pot synthesis of biomimetic glutathione peroxidase with temperature responsive catalytic behaviors

“…[45][46][47] In addition, the one-pot method presents a unique advantage in the simple and efficient preparation of functional materials. [48][49][50] Inspired by these, a new strategy based on the combination of ATRP and one-pot method is worthwhile to be explored for the biomimetic GPx with high efficiency temperature response catalytic activity. In this work, a temperature responsive microgel biomimetic GPx was successfully constructed by a one-pot method using N-isopropylacrylamide, tellurium-containing polymerizable monomer (Te monomer) and acrylamide.…”
