Nanotechnology Synthesis

INTRODUCTION.

Nanotechnology is the study manipulating the properties of various materials. In the nano regime (1-100 nm) the particles behaves entirely different from there bulk state, showing some novel properties. Materials having multiple functionalities are one of the top fields of interests. Textiles showing the anti-microbial properties can be tailored via nanotechnology. Graphene oxide is a single layered material which is an oxidized form of graphene, recently GO has gained attention due to various properties shown by the material including its anti-microbial effects.

Silver nanoparticles has been shown huge variations in its property from the macro scale, it’s one of the most studied nanoparticles. The silver nanoparticles has been

Take sodium borohydrate in beaker to which silver nitrate solution were added drop wise under constant stirring, the color of the solution varies from colorless to pale yellow and then to golden yellow indicating the formation of silver nanoparticles.

Synthesis of ZnO Nps The combustion method were used for the synthesis of ZnO Nps, in which the precursors Zinc Nitrate , Urea , Glycin of 2g, 1g and 0.5g respectively were taken in a beaker, add distilled water to the above mixture until the solution becomes clear. The beaker is then placed in a hot plate and allowed the combustion to take place, the product after the combustion was then calcinate at 6000 C for 6 hours in a muffle furnace.

Decoration of the cotton fabric

(a) 0.2g of Graphene Oxide is taken and made up to 10mL by adding distilled water to the beaker cotton fabric of 5cm2 is dipped along with the solution and subjected to probe sonication for 10min.

(b) 0.1g of GO and 0.1 g of ZnO were taken in a beaker to it 10mL of distilled water was added and to the solution the cotton fabric was dipped and subjected to
