[0024] The present invention provides a method for preparing cuprous oxide-nonwoven fabric nano composite material, which includes the following steps:
[0025] (1) After ultrasonically mixing nano cuprous oxide with absolute ethanol, a dispersion of nano cuprous oxide is obtained;
[0026] (2) Put the nano cuprous oxide dispersion and the non-woven fabric obtained in the step (1) into a transparent sealed container and perform electron beam irradiation to obtain a copolymer;
[0027] (3) Drying the copolymer obtained in step (2) under light-shielding conditions to obtain a cuprous oxide-nonwoven nanocomposite material.
[0028] In the present invention, after ultrasonically mixing the nano cuprous oxide with absolute ethanol, the nano cuprous oxide dispersion liquid is obtained. In the present invention, the particle size of the nano cuprous oxide is preferably 50 to 300 nm, more preferably 60 to 200 nm, and most preferably 80 to 100 nm.
[0029] The present invention does not specifi...
Embodiment 1
[0048] (a) Dissolve 0.3992 g of copper acetate in 25 mL of azodicarbonamide (about 2.5% water);
[0049] (b) At room temperature, add 500mg polyvinylpyrrolidone (dispersant, control product size) and 0.025g sodium borohydride (reducing agent) to the solution obtained in step (a) at room temperature, and ultrasonic (60HZ) until it is completely dissolved. Stir on a magnetic stirrer (500rpm) for about 5 minutes;
[0050] (c) Place the solution obtained in step (b) in an oil bath at 70°C and heat and stir for about 4 minutes, until the solution gradually turns orange;
[0051] (d) Let the solution obtained in (c) stand and cool to room temperature, pour it into a plastic centrifuge tube, immerse and centrifuge in ethanol three times (5000rpm, 5min), dissolve the solid product in 1.5mL ethanol, pour it into a watch glass, And put it in an oven to dry (30°C, 24h) to obtain nano cuprous oxide solid;
[0052] (e) Weigh 0.01g of the nano cuprous oxide solid obtained in (d) and dissolve it in...
