Adsorption of organic peroxides on the surface of amourphous alloys for the drugs immobilization

Abstract

It was investigated wetting of surfaces of the amorphous metallic alloys (AMA) based on iron and cobalt with aqueous-ammonium solutions of oligoperoxides based on vinyl acetate, 2-tert-butylperoxy-2-methyl-5-hexen-3-yne and maleic anhydride (OP-1) and based on vinyl acetate, 3-tert-butylperoxy-3-phenylbutylmethacrylate and maleic anhydride (OP-2). The surface tension of thin films of oligoperoxideʼs aqueous-ammonia solutions was determined and were calculated values of the macromolecules adsorption. A higher surface activity of OP-2 was observed in comparison with OP-1. The values ​​of the adhesion work between contact and external metallic surfaces and solutions of oligomers were calculated.
