    Abstract: The invention comprises an environmentally benign method for the direct in situ preparation of copper nanoparticles (CuNPs) in paper by reducing sorbed copper ions with ascorbic acid. Copper nanoparticles were quickly formed in less than 10 minutes and were well distributed on the paper fiber surfaces. Paper sheets were characterized by x-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, and atomic absorption spectroscopy. Antibacterial activity of the CuNP sheets was assessed for by passing Escherichia coli bacteria suspensions through the papers. The effluent was analyzed for viable bacteria and copper release. The CuNP papers with higher copper content showed a high bacteria reduction of log 8.8 for E. coli. The paper sheets containing copper nanoparticles were effective in inactivating the test bacteria as they passed through the paper. The copper levels released in the effluent water were below the recommended limit for copper in drinking water (1 ppm).

    Abstract: A (meth)allylsilane compound chemically bonded to various alcohol derivatives including polyol derivatives such as saccharides, is raw material used to cause a substrate to express functionalities such as a defogging property and separation characteristics for column chromatography, can be easily prepared, is easily purified, and is stable and easy to handle, and a functional material in which those functionalities are expressed, while silyl group-containing groups are conveniently carried at a high density on the surface of the substrate, by using the (meth)allylsilane compound as a silane coupling agent for silane-coupling to the substrate. The (meth)allylsilane compound includes a (meth)allylsilyl group-containing alkyl group or a (meth)allylsilylalkyl group-containing aralkyl group that is bonded to an alcohol derivative. In the functional material, the silane coupling agent is ether-bonded to surface hydroxyl groups exposed on a substrate through the surface hydroxyl groups by silane coupling to have an ether bond on the functional material.
