Method for producing flexible antennas that work within GHz band, based on reduced graphene oxide

摘要

the subject of the invention is a way of flexible antennas operating in the ghz based on reduced graphene oxide of any shape on a flexible substrate.implementation of flexible antennas operating in the ghz based on reduced graphene oxide of the invention uses the method of printing inkjet printing layers of graphene oxide.using the printer inkjet guided computer developed template printing on pet substrate by ink is applied.it contains flakes of graphene oxide suspended in ethylene glycol propylene glycol with a density of 1 - 1.3 g / cm3, flow index 0.80 - 0,95, controlling 12.0 - 12.3 mpas and surface tension - 35.0 30.0 mj / s2.the layer of ink is applied jednoprzebiegowo in volume 1 - 1.2 ml / cm2. subsequently, a printout is dried at 60 - 70u00b0c for 30 - 40 minutes.in the next stage of drying print is given on the table working laser uv remote computer according to the prepared template and subjected to reduction, whereby the power beam is 1 - 2,the outbreak of 4.5 - 5 mm, and the velocity of 100 - 120 cm / s. so prepared antenna is secured uv varnish.
