摘要：
Structural organization and antimicrobial properties of nanocomposites based on pectin, polyethyleneimine and Ag nanoparticles, which formed by the chemical and thermal reduction methods from interpolyelectrolyte-metal complexes (IMC) pectin-Ag+-polyethyleneimine have been investigated. Such type of nanocomposites with Ag nanoparticles incorporated into polymer matrix is obtained due to the chemical reduction of Ag+ ions by NaBH4 in the interpolyelectrolyte complex, and appearance of the silver metallic phase is observed in full extent while BH4-: Ag+ molar ratio is equal to 2.0. It is defined that thermal reduction of Ag+ ions in IMC bulk (while films are heated to the temperature around 100 degrees C and more) results in formation of nanocomposites. The antimicrobial investigation of the elaborated nanocomposites revealed they possess a high antimicrobial activity against S. aureus and E. coli strains.
