| Abstract: | A series of thiourea-chitosan-Ag complexes were synthesized. The structure of as synthesized products was characterized by means of Fourier transform infrared spectrometry, and the antimicrobial performance of chitosan, thiourea-chitosan and four thiourea-chitosan-Ag complexes against bacteria and plant pathogenic fungus was evaluated. Results show that as- synthesized thiourea-ehitosan-Ag complexes have obviously enhanced antimicrobial activities than chitosan and thiourea-chitosan. Besides, the antimicrobial activity of four thiourea-chi- tosan-Ag complexes rises obviously with increasing content of Ag＋. |
