Liquid crystalline (LC) elastomers are well known for their reversible shape variation at the phase transition from the LC to the isotropic phase. We managed to prepare an oriented smectic monodomain of a crosslinked LC-polysiloxane, which showed – contrary to the expectations – NO shape variation at all. This observation is in agreement with mechanical measurements on small LC-elastomer balloons made from the same materials. It is completely unknown, why this type of “diluted” LC-polysiloxane (only about 25% of the repeating units are functionalized with mesogens) behaves like this.

  1. […] can find the article on the website of the Journal of Unsolved Questions for […]

  2. excellent points altogether, you just gained a new
    reader. What would you suggest in regards to your publish that you simply made some days ago?
    Any certain?
