Synthesis of metal–polymer nanocomposite for optical applications

Abstract

Thin films of Ag–PET nanocomposite were synthesized by a novel route of atom beam co-sputtering. The nanocomposites were characterized by UV–visible and IR absorption spectroscopy, Rutherford backscattering spectroscopy and transmission electron microscopy. The absorption spectra exhibit features suitable for applications as (i) absorber extending from the visible region to about 2400 nm in the infrared region and (ii) bandpass filter at 320 nm, useful for HeCd laser. The transmission electron microscopy observations indicate that the metal fraction is in the form of fractals.

Metal-Polymer Nanocomposites: (Co-)Evaporation/(Co)Sputtering Approaches and Electrical Properties

“…A well-established method to produce metal NPs/polymer composites is the co-depositions of polymers and metals [9,[42][43][44][45][46][47][48][49][50][51][52][53][54]. Co-evaporation and co-sputtering of a metal and of an organic component have been reported to produce functional polymer composites containing metal NPs.…”

“…This approach allows a fine control, in a wide range, of the metal filling factor, filling factor profile, and composition of the particles. Exploiting such methodologies, several types of metal-polymer nanocomposites were produced with interesting physical properties for functional applications: Ag NPs embedded in polyethylene terephthalate for optical applications [42], Fe-Ni-Co NPs and nano-columns embedded in Teflon AF for magnetic-based applications [44,45], Ag NPs embedded in a polymer matrix of Teflon AF for plasmonic-based applications [46], Ag NPs embedded in polytetrafluoroethylene for electrical and optical applications [47], Au and Ag NPs embedded in Teflon AF and Nylon matrices for electrical applications [48], Ag-Au and Ag-Cu alloy NPs in Teflon AF matrix for plasmonic-based applications [49,50], Au and Ag NPs embedded in polytetrafluoroethylene for antimicrobial applications [54].…”

Stretchable metal-elastomer nanovoids for tunable plasmons

“…Relatively few mechanically tunable plasmonic structures have been demonstrated, with examples limited to tunable gratings 12,13 and plasmonic particle arrays embedded in a polymer matrix. 14 Here we use a self-assembly and casting technique to fabricate a range of flexible metal-elastomer nanostructures, which have mechanically tunable plasmonic properties. A wide variety of nanostructures can exploit this fabrication procedure including ͓Fig.…”

Synthesis and characterization of novel antibacterial poly(imidosulfide)/Ag nanocomposite

“…They also used in preparation of metal-polymer nanocomposites, which are lighter than pure metals [18] and also show better electrical, thermal, mechanical, and optical properties compared with the polymer [19][20][21]. Among them, silver nanocomposites has received much attention in recent decades due to their wide range of application in different filed such as; catalysis, medicine and wound dressings, optical data storage devices, electrochromic and increased Raman scattering to store information [22] and their unique antibacterial activity [23][24][25].…”
