Inkjet Printing Ionic Liquids for the Fabrication of Surface Structures on Biopolymer Substrates
Ionic liquids (IL) have been the focus of materials research for some time due to their unique physical and chemical properties. Of significant interest is their ability to solubilize biopolymers such as cellulose and silk[iv]. When paired with inkjet printing, these ILs allow for variable, reproducible modification of biopolymers. By incorporating materials of interest into these IL inks, inkjet printing presents an extremely powerful tool for small scale fabrication with a myriad of applications. In this research we will discuss the modification of surface structures through the inkjet printing of neat IL, IL’s containing nano and micro-scale particles, and IL/polymer solutions.
