“…However, printing of electronic circuit on polymers for flexible electronics is a challenging attempt as there is no strong interaction between metal particles like Ag, Au, Ni and Cu with polymers [1]. Different practical issues such as diffusion, interfacial reactivity, weak metal-polymer adhesion, blistering /metalmetal complex in metal-metal interface, weak mechanical properties of resulting metal-polymer film hinder success of metallization of polymer film [2,3]. Consequently, though metalized polymer films have been the interest of research for decades, and highly reflective or/and conductive flexible polymer films have been obtained via different multi-step or single-step synthesis methods [4][5][6][7][8][9][10][11], synthesis of flexible, electrically conductive polymer film with good mechanical strength, and metal-polymer adhesion by a simple and costeffective method has not been observed yet.…”

KEYWORDSFlexible nanostructured and conducting metal-polymer films have been found promising applications in pharmaceuticals and flexible electronics. These could be used as anti-bacterial agent, bio-warfare treatment, or as sensors for environmental monitoring and protection. However, mechanical strength and metal-polymer adhesion are crucial issues for practical applications of such films. Another issue associated with synthesis of such polymers is the necessity of a simple, convenient and cost-effective method. This work focused on the above issues and reports the synthesis of nanostructured Ag-polymer films (brown, blue and golden colored) and conductive Au-Ag-polymer film with a good combination of flexibility, mechanical strength and metal-polymer adhesion. The films were synthesized by simple and cost-effective routes. Ag-polymer films were prepared by one-step method through studying the effect of metal concentration and curing process. Conductive film was obtained by gold plating on the selected Ag-polymer film. SEM and EDS clearly indicated the existence of metal particles on the metal-polymer films.

Abstract. The unique properties of nanotextiles based on poly(vinyl-alcohol) (PVA) manufactured using the electrospinning method have been known and exploited for many years. Recently, the enrichment of nanofiber textiles with nanoparticles, such as ions or nanodiamond particles (NDP), has become a popular way to modify the textile mechanical, chemical and physical properties of the textile. The aim of our study is to investigate the macromechanical properties of PVA nanotextiles enriched with NDP, silver (Ag) and copper (Cu) ions. Nanofiber textiles of various surface weights were prepared from a 16 % PVA solution, while glyoxal and phosphoric acid were used as cross-linking agents. The copper and silver ions were diluted in an aqueous solution and NDP were dispersed into the fibers by ultrasound homogenization. All but one of the sets of samples were exposed to a temperature of 140°C for 10 minutes. The samples without thermal stabilization exhibited significantly lower elastic stiffness and tensile strength. Moreover, the results of tensile testing indicate that the addition of dispersed nanoparticles has a minor effect on the mechanical properties of the textiles and contributes rather to their reinforcement. However, the lack of thermal stabilization results in a poor interconnection of individual nanofiber layers, and the non-stabilized textiles exhibit lower elastic stiffness and reduced tensile strength.

“…Many properties of the metallic polymer films are influenced by the degree of metal mobility in the polymer and/or the possible reactions of the metal with the polymer [5]. To improve the diffusion depth or to enhance reactions, many methods treat metal depositions at elevated temperatures [6][7][8][9]. As a result the aggregation tendency of metals and the possible destruction of the structure of the polymers, cannot be avoided [10].…”

The nickel ion containing Langmuir-Blodgett (LB) multilayer was prepared by transferring nickel acetate, spread on the surface of a sub-phase of ultra-pure water and stearic acid-chloroform mixture, onto an interpenetrating polymer network (IPN) substrate. The substrate was prepared by dip-pulling a hydrophilic silicon wafer or a glass plate into precursors, followed by solidification at room temperature, in order to create an ultra-thin and uniform surface for metal deposition. The multilayer was then converted into an ultra-thin nickel film after chemical reduction by 0.01 mol/l sodium borohydride. The surface pressure of the monolayer and dipping speed of substrate were determined by measuring the transfer coefficient. Fourier transform infrared spectroscopy (FT-IR) was used to investigate the interactions of the nickel ions with the IPN during the multilayer deposition on substrate, and the metal transformations of nickel ion in the ultrathin film. The shifted peak location for -C=O verified the interactions between the IPN and the nickel ion and the transformation of the nickel ion by reduction. Further reduction caused the organic phase to dissolve, resulting in most of it being removed from the multilayer. The surface morphologies of the LB multilayer were detected by atomic force microscopy (AFM). Compared with the IPN, which formed a uniform and flat film, within a range of nanometers, the Ni/IPN multilayer and Ni ultra-thin film both showed some surface fluctuations, although these were still within nanometer range. The roughness of the nickel ion containing multilayer and the ultra-thin nickel film was 1.123 nm and 0.773 nm with a maximum height of 12.451 nm and 14.933 nm, respectively, which were larger than that of pure IPN substrate of 0.593 nm with the max height of 6.795 nm.
