Responsive polymers have been explored for both fundamental and applied studies due to their ability to undergo conformational and chemical changes upon receiving an external stimulus. In this work, we report the wetting behavior of poly(N-isopropylacrylamide-block-styrene) diblock copolymer films, ...
Stimulus-responsive polymer brushes (SRPBs) exhibit a change in conformation and structure, often accompanied by a noticeable change in surface energy, due... C Tao,R Ferris,J Zhang,... - 《Progress in Polymer Science》 被引量: 366发表: 2010年 Temperature-responsive permeability of porous PNI...
Along with ease of administration, prolonged retention in nasal cavity and sustainable drug delivery, these systems possess some additional advantages such as, polymers used in stimulus responsive in situ nasal gel may have absorption enhancement effect on drug e.g. chitosan derivatives like trimethyl ...
A stimulus-responsive magnetic nanoparticle drug carrier: Magnetite encapsulated by chitosan-grafted-copolymer We describe a magnetic nanoparticle drug carrier for controlled drug release that responds to the change in external temperature or pH, with characteristic...

(red; left) and fluorescence lifetime images of FPT (middle and right). (c) Control experiment for (b) No significant change in the fluorescence lifetime of FPT was detected without a chemical stimulus. In (a–c), the temperature of the medium was maintained at 30 °C. Scale bar ...
Shape memory polymers (SMPs) can be deformed into a temporary shape and then return to the orig- inal shape under an external stimulus, and the shape memory effects are attributed to the coexistence of one phase allowing for shape fixity and the other phase allowing for reversibility, where ...
