Abstract

Istotą wynalazku jest sposób otrzymywania folii na bazie komponentów z nanosrebrem, który charakteryzuje się tym, że do proszku alginianu sodu lub agar-agar lub ich mieszaniny w ilości od 1 do 20% dodaje się sproszkowaną karboksymetylocelulozę w ilości od 0,05 do 5%, glicerol w ilości od 0,4 do 4% i wodę korzystnie destylowaną lub demineralizowaną w ilości do 100% wagowo i miesza korzystnie w czasie od 1 do 30 min, a następnie dodaje się sproszkowane srebro o wielkości cząstek od 5 do 100 nm w ilości od 1 do 70% wagowo, i miesza korzystnie w czasie od 1 do 30 min i spienia lub od razu formuje się termicznie w temperaturze od 50 do 200°C na oczekiwany kształt i na tak otrzymany materiał nanosi się korzystnie natryskowo chlorek wapnia dwuwodnego i suszy.The essence of the invention is a method of obtaining films based on components with nanosilver, which is characterized in that powdered carboxymethylcellulose in an amount of 0.05 to 5% is added to sodium alginate or agar-agar powder or their mixtures in an amount of 1 to 20%, glycerol in an amount of 0.4 to 4% and water, preferably distilled or demineralized water in an amount of up to 100% by weight, and preferably mixed for 1 to 30 minutes, and then silver powder with a particle size of 5 to 100 nm is added in an amount from 1 to 70% by weight, and preferably mixed for 1 to 30 minutes, and foamed or immediately thermoformed at a temperature of 50 to 200 ° C to the desired shape, and the material thus obtained is preferably sprayed with calcium chloride dihydrate and dried.
