The long-term goal of this line of research is to develop a disruptive printed memory resistor or �memristor� in the form of multi-functional colloidal particles that can be printed into devices using additive manufacturing tools. The central hypothesis is that sub-100 nm particles can be formed from non-conjugated polymers that exhibit inherent path-dependent conductive (PDC) characteristics and printed into memristors. This new memory alters its conductivity based on its electronic history and instead of encoding �0�and �1� as the amount of charges stored in a traditional silicon-based cell, the low and high conductivity condition is interpreted as the OFF and ON states. One of the very appealing aspects of this device is that both information retention and processing could be combined in a single device. Two specific objectives will be presented: (1) the structure/property relationships that underlie resistive switching in non-conjugated polymers with pendant carbazole and oxadiazole moieties can be determined and (2) printable inks can be formulated from these resistive switching polymers and employed in printing equipment to produce colloidally-derived memristors.
