Embodiment 1

[0116] Silver nanoparticles were e-beam evaporated onto PVA films at a nominal thickness of 40 Angstroms. The electron beam deposition rate was 5 Angstroms / sec. The resulting coated film had a light yellow / amber hue. Spectra were taken using UV-Vis HP 8452A.Rev.A. Using a 2 nm sampling interval and a 0.5 second integration time, the spectrophotometer showed a nanoparticle resonance at 412 nm, as shown in Figure 1. A stock solution was prepared by dissolving 0.9 g of the film-coated sample in 157 g of distilled water at room temperature. Additional solutions were prepared by further diluting stock solution samples to 50 and 25% with distilled water. It should be noted that these solutions are stable over a year with no signs of aggregation.

[0117] The spectra of these solutions were acquired in a cell with a 1 cm path length. The results are shown in FIG. 2 . Evaporation of a sample of the stock solution yielded a very viscous liquid. The spectrum of the liquid was obt...

Abstract

A metallic nanoparticle coated water-soluble polymeric substrate and the process for preparing and using the same is described.

Description

technical field [0001] The present invention relates to a water-soluble polymer substrate coated with metal nanoparticles and methods for its preparation and use. Background technique [0002] Metal nanoparticles with diameters of about 1-100 nanometers (nm) are important materials for a variety of applications including semiconductor technology, magnetic storage, electronic device manufacturing, and catalysis. Metal nanoparticles were prepared by the following methods: vapor phase evaporation; evaporation in a flowing gas stream; mechanical milling; sputtering; electron beam evaporation; thermal evaporation; electron beam-induced atomization of binary metal azides; Expansion of metal vapors; reverse micelle technology; laser ablation; laser-induced dissociation of organometallic compounds; pyrolysis of organometallic compounds; microwave plasma decomposition of organometallic compounds, and other methods. [0003] It is well known that metal nanoparticles have unique optic...
