I am looking to make metallic ink for inkjet printing and using PEO 1 wt% (MW ~600,000) as a binder. The print head I am hoping to use has a nozzle diameter of 80 microns. The metal powder dispersed in the ink is ~100nm. If I dissolve the PEO into deionized water, will the PEO particles be too big to pass through the nozzle? The PEO purchased is from sigma aldrich (https://www.sigmaaldrich.com/catalog/product/aldrich/182028?lang=en®ion=IE)

Thanks :)
