In situ synthesis of hybrid nanocomposite with highly order arranged amorphous metallic copper nanoparticle in poly(2-hydroxyethyl methacrylate) and its potential for blood-contact uses

Facile preparation of L-ascorbic acid-stabilized copper-chitosan nanocomposites with high stability and antimicrobial properties

“…/Cu 0 ) = 0.34 V) [26], which enables it to grab electrons from amine groups. When Cu(Ac) 2 [18,27]. The gap of *19.8 eV between the two peaks was also indicative of metallic Cu 0 [28].…”

“…In particular, the smaller the nanoparticles are, the more easily they become oxidized. To overcome these obstacles, researchers have used inert gas and different sorts of polymers [17,18] as dispersants to protect Cu NPs during the synthesis process. Lactic acid [19] and iodine [20] have also been used as protecting agents.…”

Diffusion behavior of copper atoms under Cu(II) reduction in Cucurbit[8]uril cavity at elevated temperatures

“…There are some methods of metal NP's encapsulation inside organic cavitands [12]. Gold NPs inside macrocycle cavitand cucurbit [7]uril, CB [7], have been included by Au vapor adsorption [12]. Also, it was shown that gold clusters might be encapsulated in CB[n] cavity due to reducing HAuCl 4 gold complexes located inside cavitands by NaBH 4 .…”

“…It is mentioned that inorganic/ organic hybrid materials have long attracted much attention because beneficial properties of their individual components act synergistically [7]. A few methods to avoid metal particle agglomeration and their size stabilization by a cover containing suitable ligands are known [8][9][10][11][12][13][14][15][16][17][18].…”

Super-Adhesive Polymer–Silica Nanocomposite Layers

“…zinc oxide, 2 calcium carbonate, 18 or silica 19,20,21 ) to the polymer, and used for the improvement of luminescence, 2 water uptake, 21 or mechanical properties of materials. 18,19,20 Previous methods for preparing poly(2-hydroxyethyl methacrylate) nanocomposite layers have included sol-gel reaction, 2,19,20 free radical polymerization, 22 photopolymerization, 23,24 emulsion polymerization, 25,26 controlled radical polymerization, 27,28 in-situ reduction 29,30 and solution intercalation. 31 Such wet chemical approaches tend to require catalysts, 27 high temperatures, 20 multiple steps, 2 or long reaction times.…”
