“…Composites made by mechanical mixing of metal nanoparticles and molten polymers generally lead to inhomogeneous particle dispersions. As a consequence, various approaches have been proposed to manufacture metal nanocomposites including ball milling, coevaporation and sputtering of metals and polymers, plasma polymerization, and new synthetic procedures [12][13][14][15]. Among these last approaches, it is important to mention the use of different agents in order to increase nanoparticle stability, the simultaneous photoinduced electron transfer and cationic polymerization, the thermal and UV in situ polymerizations [16][17][18][19][20][21][22].…”

Abstract. Silver-polyacrylonitrile (Ag-PAN) nanocomposites were in situ synthesized by simultaneous polymerization of acrylonitrile and reduction of silver ions, starting from mixtures of silver nitrate (AgNO3), acrylonitrile (AN), and UV photoinitiator (IN). The films obtained proved to be transparent and were characterized by a homogeneous dispersion of Ag nanoparticles within the PAN matrix without any macroscopic agglomeration. The particle size and number density were found to depend on both precursor salt and UV photoinitiator weight percentages. Optical and electrical properties were investigated as a function of both AgNO3 and IN amounts, too. We found that it is possible to finely tailor the metal nanoparticle size and number density and, consequently, the film optical and electrical response by adjusting the amounts of precursor salt and UV photoinitiator in the initial mixtures.

“…The main structural parameter of the metal-polymer nanocomposite film, determining its physical properties (i.e., optical, electrical, etc.) is the volume metal filling factor f [44][45][46][47][48][49][50]. It can be defined as [47] …”

“…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].…”

Abstract:In this review, we discuss the basic concepts related to (co-)evaporation and (co)sputtering based fabrication methods and the electrical properties of polymer-metal nanocomposite films. Within the organic-inorganic hybrid nanocomposites research framework, the field related to metal-polymer nanocomposites is attracting much interest. In fact, it is opening pathways for engineering flexible composites that exhibit advantageous electrical, optical, or mechanical properties. The metal-polymer nanocomposites research field is, now, a wide, complex, and important part of the nanotechnology revolution. So, with this review we aim, starting from the discussion of specific cases, to focus our attention on the basic microscopic mechanisms and processes and the general concepts suitable for the interpretation of material properties and structure-property correlations. The review aims, in addition, to provide a comprehensive schematization of the main technological applications currently in development worldwide.

Laser Ablation Direct Writing of Metal Nanoparticles for Hydrogen and Humidity Sensors

A UV pulsed laser writing technique to fabricate metal nanoparticle patterns on low-cost substrates is demonstrated. We use this process to directly write nano-particle gas sensors, which operate via quantum tunnelling of electrons at room temperature across the device. The advantages of this method are: no lithography requirements, high precision nanoparticle placement and room temperature processing in atmospheric conditions. Palladium based nanoparticle sensors are tested for the detection of water vapour and Hydrogen within controlled environmental chambers. The electrical conduction mechanism responsible for the very high sensitivity of the devices is discussed with regard to the inter-particle capacitance and the tunnelling resistance.2
