Study on Morphological Structure and Application of Ag-La-Inorganic Antibacterial Material Dying by Microwave

Abstract

This paper investigated the morphological structure and application of the Ag-La-inorganic antibacterial material. The sol-gel method was used to prepare the carrier: White Carbon Black. Silver ion was selected to be the antibacterial ion, and lanthanum nitrate was selected to be the additive. The morphological structure and application of this new inorganic antibacterial material were characterized by inductively coupled plasma (ICP), scanning electron microscope (SEM) techniques, energy dispersive spectrum (EDS) analysis, antibacterial activity test (Escherichia coli as experimental bacterium) and application experiment. Results showed that the amount of antibacterial ion of the Ag-La-inorganic antibacterial material was higher than that of the general Ag-inorganic antibacterial material. And its bacteriostasis rate was also higher than that of the general Ag-inorganic antibacterial material. Other advantages of this material are its loose and dispersive structure. In addition, this new inorganic antibacterial material showed promising result in rubber.
