The invention provides a modified silver nanowire transparent conductive film and a method for improving the conductivity and oxidation resistance of the silver nanowire transparent conductive film, and relates to the technical field of flexible transparent conductive films. A modified silver nanowire transparent conductive film is prepared by the following method for improving the conductivity and oxidation resistance of the silver nanowire transparent conductive film: using ethanol-water as a mixed solvent of NaBH4 solution to the silver nanowire transparent conduction The first surface treatment is carried out on the film; the second surface treatment is carried out by contacting the silver nanowire transparent conductive film which has undergone the first surface treatment with a solution of n-alkylthiol. This method can effectively reduce the contact resistance between NW-NW and enhance the oxidation resistance of silver nanowires in air. The modified silver nanowire transparent conductive film has high light transmittance, good electrical conductivity, strong oxidation resistance and bending ability, and has good application prospects.

Organic complex composite phenolic resin of nickel and preparation method of organic complex composite phenolic resin

InactiveCN102617817AImprove the residual carbon rateImprove antioxidant capacityCarbon compositesPhenol formaldehyde resin
The invention relates to organic complex composite phenolic resin of nickel and a preparation method of the organic complex composite phenolic resin. According to the technical scheme, the preparation method comprises the following steps of: adding an organic complex of the nickel into phenolic resin diluted by absolute ethanol, wherein according to the addition amount, a mass ratio of a nickel element in the organic complex of the nickel to the nickel in phenolic resin diluted by the absolute ethanol is (0.001-0.05):1; stirring at the temperature of between 20 and 60 DEG C for 1 to 6 hours; and putting into an evaporator, and distilling at the temperature of between 30 and 60 DEG C under the pressure of between 0.08 and 0.09 MPa for 0.5 to 4 hours to obtain the organic complex composite phenolic resin of the nickel. Compared with simple substance or compound composite phenolic resin of other transition metal elements and a preparation method, the invention has the advantages that theproduction cost is low; and the organic complex composite phenolic resin of the nickel is high in dispersity, residual carbon rate and oxidation resistance. The prepared organic complex composite phenolic resin of the nickel is used as a bonding agent to prepare a carbon composite refractory, so that the breaking strength at normal temperature is improved obviously.
