Embodiment 1
[0061] Embodiment 1: adopt method one to prepare the antibacterial coating that contains porous organism
[0062] 1) Take a certain amount of micron silver powder, put it into the radio frequency induction plasma powder making equipment, heat and spheroidize the powder, add 20wt% absolute ethanol to the prepared powder, disperse at a high speed, and then classify with a tubular centrifuge 2- 3 times, finally get a powder with good dispersibility and dry it in a vacuum oven at 35-45°C for use;
[0063] 2) Take a certain amount of Ti(OH) 4 , using radio frequency induction plasma to prepare nano-titanium dioxide powder, add 20wt% absolute ethanol to the prepared powder, disperse at high speed, then classify 2-3 times with a tubular centrifuge, and finally get a powder with good dispersibility at 35- Dry in a vacuum oven at 45°C for use;
