TLDR
In this article, a review examines physico-chemical requirements necessary to achieve stimuli-responsiveness in heterogeneous polymer networks as well as discusses recent developments and future trends while individual structural components of polymeric networks are responsible for localized chainresponsiveness, desirable spatial and energetic network properties are necessary for collective and orchestrated responsiveness to external or internal stimuli.About:

Thermal-mechanical behavior of styrene-based shape memory polymer tubes
TL;DR: In this article, the shape fixity ratio and shape recovery ratio of SMP tubes were investigated at different heating rates, and the tensile, compression, bending and twisting shape memory properties of the tubes were analyzed and discussed.

3D and 4D printing of pH-responsive and functional polymers and their composites
Aqib Muzaffar,M. Basheer Ahamed,Kalim Deshmukh,Tomáš Kovářík,Tomáš Křenek,S. K. Khadheer Pasha +5 more
TL;DR: The pH-responsive polymer shows transitions above or below a critical pH value of globule-to-coil nature, while functional materials display specific morphologies and characteristics revealing their ability to perform some crucial chemical, physical, and biological functions as mentioned in this paper.
Journal ArticleDOI
Stimuli-sensitive cross-linked hydrogels as drug delivery systems: Impact of the drug on the responsiveness.
TL;DR: This review gathers relevant examples of how the drug may modify the sensitiveness (stimulus threshold) and the responsiveness (actuation) of the DDS to therapeutically relevant stimulus, and aims to shed light on the different drug binding modes of the swollen and collapsed states, which in turn modify drug release patterns.
Journal ArticleDOI
Amino-acid-based zwitterionic polymer and its Cu(II)-induced aggregation into nanostructures: a template for CuS and CuO nanoparticles.
TL;DR: The Cu(II)-PLAM aggregates are used as a template for fabrication of CuO and CuS nanoparticles and appear to dissociate via breaking of the complexation at a pH < 5.5 resulting in molecular dissolution of PLAM.
Journal ArticleDOI
Hyperbranched polycaprolactone-click-poly(N-vinylcaprolactam) amphiphilic copolymers and their applications as temperature-responsive membranes
TL;DR: These stimuli responsive membranes with controllable morphology, improved mechanical properties and negligible cytotoxicity are useful as biomaterials for controlled drug delivery.

How useful is SBF in predicting in vivo bone bioactivity
Tadashi Kokubo,Hiroaki Takadama +1 more
TL;DR: Examination of apatite formation on a material in SBF is useful for predicting the in vivo bone bioactivity of a material, and the number of animals used in and the duration of animal experiments can be reduced remarkably by using this method.
Journal ArticleDOI
Conjugated polymer-based chemical sensors.
TL;DR: When considering new sensory technologies one should look to nature for guidance, as living organisms have developed the ultimate chemical sensors.

Photomechanics: directed bending of a polymer film by light.
TL;DR: It is shown that a single film of a liquid-crystal network containing an azobenzene chromophore can be repeatedly and precisely bent along any chosen direction by using linearly polarized light.
