“…Usually, for stable concentrated copper sol, a surfactant (e.g. CTAB) and/or a polymer (PVP) are used as protective ligands [24,25]. Use of two protective ligands seems to be beneficial for forming small stable particles [24].…”

“…CTAB) and/or a polymer (PVP) are used as protective ligands [24,25]. Use of two protective ligands seems to be beneficial for forming small stable particles [24]. We also used similar strategy, but a pair of polymers, PVP-PEG has been used instead of polymer-surfactant pair to obtain small stable particles at a copper salt concentration of 0.02 M. The concentrations of polymers were maintained at the same level as reported by other investigators [26][27][28].…”

“…Other synthesis protocols also use such a large excess of polymer or surfactant to synthesize copper sol at high concentration. The protocol given by Tian et al [24] uses a mass ratio of stabilizing agent to copper as 93. Similar trends have been observed for many other protocols as summarized in Table 1.…”

“…Figure 4 displays the XRD patterns of pure PVA and irradiated Cu/PVA nanocomposites with various Cu 2+ ion molar concentrations. 38 The crystallite size of the Cu nanocrystals was determined for the (111) peak using the well-known Debye-Scherrer's equation 39 given by The prominent strong broad peak at 2θ = 19.5°corresponds to the 110 reflection, a plane which contains the extended planner zigzag chain direction of the crystallites.…”

Radiation‐Induced Synthesis of Copper/Poly(vinyl alcohol) Nanocomposites and Their Catalytic Activity

Copper/poly(vinyl alcohol) (Cu/PVA) nanocomposites were synthesized using gamma radiation-induced method and characterized by various analytical techniques. UV-vis absorption spectra showed that the surface plasmon resonance bands of the Cu nanoparticles around 580 nm were redshifted with increasing both irradiation dose and Cu 2+ ion concentration The FTIR spectrum provides sufficient evidences for the involvement of PVA in stabilizing the Cu nanoparticles. The X-ray diffraction patterns show the formation of the Cu nanoparticles in a face cubic structure with different sizes as a function of either irradiation doses or Cu 2+ ion concentrations. The size of the as-prepared Cu nanoparticles ranged from 13.9 to around 19 nm. On the other hand, the transmission electron microscopy showed that the obtained Cu nanoparticles were monodispersed and had uniform particle size distribution. The rate of the catalytic degradation for a methyl orange dye was found to increase with increasing amount of the Cu nanoparticles content, which could be attributed to higher dispersity and small size of the nanoparticles. Also, the conductivity of PVA increases with incorporation of Cu nanoparticles into PVA matrix. C 2016 Wiley Periodicals, Inc.

Silver nanoparticles (AgNPs) were synthesized in reverse microemulsions using silver nitrate as silver source, hydrazine hydrate as reducing agent, n‐heptane as oil phase, cetyl trimethyl ammonium bromide (CTAB) as surfactant, and isoamyl alcohol as cosurfactant. A uniform silver nanoparticles/polystyrene (AgNPs/PS) composite was further prepared by a reverse microemulsion polymerization method. The morphologies and structures of the AgNPs and the AgNPs/PS composite were characterized by UV‐visible spectroscopy (UV–vis), X‐ray diffraction (XRD), fourier transform infrared spectra (FTIR), and transmission electron microscopy (TEM). Furthermore, the molecular weight of the AgNPs/PS composite was measured by gel permeation chromatography (GPC), and the thermal stability of the AgNPs/PS composite was determined by thermal gravimetric (TG) analysis. Results show that the AgNPs have a particle size of 3–10 nm, and are almost spherical, uniform, and monodisperse both in a AgNPs colloid and in the AgNPs/PS composite. There are no characteristic peaks of silver oxide in the synthetic AgNPs and AgNPs/PS composite. The AgNPs/PS composite has a better thermal stability and a higher molecular weight than virgin PS.
