Proposal
Electronics are ubiquitous in our daily lives and there is a growing interest to include electronics in the packaging industry. Smart packaging uses printed sensors to facilitate interaction between the product and the consumer. Electronics are normally printed on planar substrates, like plastics, but these materials are not biodegradable. Paper is a promising candidate substrate for green printed electronics; however, paper porosity is an obstacle when trying to print active inks since the fibrous structure of paper gets in the way of the active networks that in turn affects electronic properties. In this work, we will discuss silver nanowire ink interaction with paper and characterize the dynamics and electrical behavior of the resulting silver nanowire-paper composites. We deposit silver nanowires on various graded filter paper of defined pore size and present trends in wicking distance, wicking speed, and electrical properties versus pore size. The goal of this work is to study the conditions that can be applied to printed electronics on paper for improved resolution.
