| Zusammenfassung: | A method for preparing magnetic power by template includes preparing polystyrene microbial by emulsion polymerization and carrying out surface modification on it to change its hydrophilic surface to be oleophylic surface as well as using it as growing template of magnetic power, dispersing said template in metal salt solution and adding NaOH or KOH for forming precipitation under strong agitation and in ultrasonic treatment, adding reducer when said unit is heated up to certain temperature to generate metal or its alloy on original position of template, obtaining magnetic power after washing and drying. |
