Preparation, characterization and antimicrobial efficiency of Ag/PDDA-diatomite nanocomposite
Original language description
Nanocomposites consisting of diatomaceous earth particles and silver nanoparticles (silver NPs) with high antimicrobial activity were prepared and characterized. For the purpose of nanocomposite preparation, silver NPs with an average size of 28 nm prepared by modified Tollens process were used. Nanocomposites were prepared using poly(diallyldimethylammonium) chloride (PDDA) as an interlayer substance between diatomite and silver NPs which enables to change diatomite original negative surface charge topositive one. Due to strong electrostatic interactions between negatively charged silver NPs and positively charged PDDA-modified diatomite, Ag/PDDA diatomite nanocomposites with a high content of silver (as high as 46.6 mg Ag per 1 g of diatomite) wereprepared. Because of minimal release of silver NPs from prepared nanocomposites to aqueous media ({ 0.3 mg Ag per 1 g of nanocomposite), the developed nanocomposites are regarded as a potential useful antimicrobial material with a long-te
