With nanometer SiOx powder as the carrier,alkylated polyethyleneimine grafted SiOx nano-antimicrobial agent was prepared by covalent grafting modification.By FT-IR,and TG to characterize the sample,the results showed that:the nano-SiOx powder was successfully grafted with organic polymer group,the prepared alkylated polyethyleneimine grafted SiOx nano-antimicrobial agent had the MIC of 400mg/L for Escherichia coli and 200mg/L for Staphylococcus aureus.It had strong antimicrobial activity,and can tolerated high temperature.The antimicrobial powder can be added to some materials such as plastics to prepare antimicrobial materials for use.
