Method for sonochemical deposition of metals on textile substrates and products thereof

A metal coated textile substrate prepared according to a method comprising:

• providing an aqueous seeding solution comprising a first metal precursor and a first metal precursor reactant, wherein the first metal precursor is AgNO3 and the first metal precursor reactant is ethylene glycol, wherein the AgNO3 is present in the aqueous seeding solution at a concentration of 0.0215 M to 0.043 M and the ethylene glycol is present in the aqueous seeding solution at a concentration of 40-80% v/v;
• irradiating the aqueous seeding solution by a first ultrasonic irradiation reaction process thereby forming a first plurality of metal nanoparticles;
• depositing the first plurality of metal nanoparticles on a textile substrate by a first ultrasonic irradiation deposition process thereby forming a metal seeded textile substrate;
• providing an aqueous coating solution comprising a second metal precursor, a second metal precursor reactant, and Fe(NO3)3, wherein the second metal precursor is Zn(OAc)2 and the second metal precursor reactant is an alkali metal hydroxide, wherein the Zn(OAc)2 is present in the aqueous coating solution at a concentration of 0.1 M to 0.6 M;
• the alkali metal hydroxide is present in the aqueous coating solution at a concentration of 0.4 M to 0.6 M;
• and the Fe(NO3)3 is present in the aqueous coating solution at a concentration of 0.01 M to 0.05 M;
• irradiating the aqueous coating solution by a second ultrasonic irradiation reaction process thereby forming a second plurality of metal nanoparticles;
• and
• depositing the second plurality of metal nanoparticles on the metal seeded textile substrate by a second ultrasonic irradiation deposition process thereby forming the metal coated textile substrate.
