Conjugated polymers for information storage and neuromorphic computing

Abstract

In the era of information explosion, silicon‐based storage can barely meet the burgeoning demand for data storage and making Moore's law no longer accurate. What is more, the traditional von Neumann architecture separates the computing module from the storage unit, which causes a slowing down of the overall computing efficiency. Conjugated polymer memristors, due to the advantages of simple fabrication, convenient operation and low cost, are considered as promising candidates for next‐generation memory and neuromorphic computing applications. This review summarizes the advances in conjugated polymer memristive materials and devices made during the first two decades of the 21st century, and their potential applications in information storage and neuromorphic computing. Focuses are on switching mechanisms and materials classifications, as well as memory, artificial synapse and bioinspired and in‐memory computing performance. © 2020 Society of Chemical Industry

Configurable switching behavior in polymer-based resistive memories by adopting unique electrode/electrolyte arrangement

“…49,50 The formed AlO x in the electrode may act as the charge trap sites, which can build up a space charge by the accumulation of charge carriers at the electrode-PMMA interface. 46,51 Similar Al electrode based resistive switching characteristics governed by SCLC conduction mechanism has already been reported. 12,52 Furthermore, the current conduction in the Al/AgNP-PMMA/Al device closely associated with the SCLC conduction mechanism.…”

Reaction of the nitrophenyl carbonate 6 with 1,4-diaminobutane resulted in the difunctional crosslinker 8 ( Figure 5), which could be subsequently used to carry out IEDDAc hemistry to crosslink polymer P1.T he crosslinking chemistry occurs rapidly over the course of several minutes, liberating ac rosslinked network polymer (see Supporting Information, Video 2, for avideo of the process).…”

“…Since their discovery,conjugated polymers have played an increasingly important role in numerous disruptive technologies.The wide array of structures that constitute the polymer backbone allows their optimization for applications that include lighting and displays, [1] energy generation and storage, [2,3] sensors, [4,5] field-effect transistors, [6,7] as well as information storage and computing. [8] Avariety of conjugated polymer properties can be modified by varying polymer structure,i ncluding band gap,H OMO and LUMO levels, extinction coefficient, quantum yield, conductivity,a nd solubility. [9][10][11][12][13][14] However,m odification of polymer properties typically requires the preparation of new polymer structures, which are prepared via de novo synthesis incorporating new monomers.…”

Controlled Bioactive Delivery Using Degradable Electroactive Polymers

“…The first examples of degradable EAP-based DDSs were based on electroactive oligomers of aniline combined with nonelectroactive blocks, , and since that time, other examples have been reported in the literature incorporating electroactive oligomers (typically oligoanilines). , The literature precedent on the toxicity of oligoanilines ,, motivates the investigation of biomaterials incorporating other electroactive moieties, for example, oligopyrroles/porphyrins, which are being developed for a multitude of technical and medical applications. − …”
