Abstract
The polydomain–monodomain (PM) transformation takes place when a polydomain of a smectic‐C main‐chain liquid‐crystalline elastomer (SmC MCLCE) is uniaxially stretched. We present results based on a combination of mechanical and X‐ray experiments which show how the domains initially rearrange to finally form a perfect conical layer distribution (monodomain) when the sample is fully stretched. The rearrangement and orientational process of the domains is quantified and compared to the parallel and perpendicular uniaxial stress–strain deformations of a monodomain sample. The stress–strain behaviour of the polydomain lays between the uniaxial deformations, parallel and perpendicular to the director, of the monodomain sample. magnified image
