The opposite gating behaviors of solid-state nanochannels modified with long and short polymer chains†
Abstract
The influence of long and short polymer chains on the gating properties of nanochannel systems modified with a NIPAAm-co-PBA copolymer have been explored. We not only discovered the negative temperature gating behavior of the NIPAAm modified nanochannel systems for the first time, but also achieve these two fully opposite gating behaviors (negative/positive) on the same platform.
