Journal ArticleDOI
Engineering of Complex Order and the Macroscopic Deformation of Liquid Crystal Polymer Networks
Laurens T. de Haan,Carlos Sánchez-Somolinos,Cees Bastiaansen,Cees Bastiaansen,Albertus P. H. J. Schenning,Dirk J. Broer +5 more
TL;DR: Rise or fall: Complex-structured freestanding polymer films with molecular order in three dimensions were prepared through photoalignment of polymerizable liquid crystals to deform into cone and saddle shapes upon heating.
Journal ArticleDOI
Humidity-responsive liquid crystalline polymer actuators with an asymmetry in the molecular trigger that bend, fold, and curl
Laurens T. de Haan,Julien M. N. Verjans,Dirk J. Broer,Cees W. M. Bastiaansen,Albertus P. H. J. Schenning +4 more
TL;DR: A versatile method for the preparation of a variety of humidity-responsive actuators based on a single sheet of a hydrogen-bonded, uniaxially aligned liquid crystal polymer network, which allows to prepare actuators that bend, fold, or curl.
Journal ArticleDOI
Accordion-like Actuators of Multiple 3D Patterned Liquid Crystal Polymer Films
Laurens T. de Haan,Vianney Gimenez-Pinto,Andrew Konya,Thanh-Son Nguyen,Julien M. N. Verjans,Carlos Sánchez-Somolinos,Jonathan V. Selinger,Robin L. B. Selinger,Dirk J. Broer,Albertus P. H. J. Schenning +9 more
TL;DR: In this article, the authors describe the fabrication, characterization, and modelling of liquid crystalline polymer network films with a multiple patterned 3D nematic director profile, a stimuli-responsive material that exhibits complex mechanical actuation under change of temperature or pH.
Journal ArticleDOI
Copper-Free Clickable Coatings
TL;DR: The first entirely copper‐free procedure for the synthesis of clickable coatings for the immobilization of functional molecules is reported, allowing qualitative comparison with the traditional CuAAC.
Journal ArticleDOI
An easily coatable temperature responsive cholesteric liquid crystal oligomer for making structural colour patterns
TL;DR: In this article, a cholesteric main-chain liquid crystal oligomer was prepared, and coated on glass using blade-coating, showing a reflection band that varied as a function of temperature over a range of several hundreds of nanometers.
