Abstract
Synthetic two- or three-dimensional structures are described that include directional negative, near-zero, or zero Poisson ratio. Methods for forming the structures are also described. Disclosed structures mimic disclination networks as occur in soft cubic blue phase high chirality liquid crystals. Disclination networks can be based upon BPI or BPII phases and can include modifications as compared to an undistorted bulk blue phase crystal.
Claims13
A method for forming a structure, comprising:
- mapping a network of disclination lines of a blue phase liquid crystal;
- scaling up the mapped network;
- and
- manufacturing a structure, the structure comprising the scaled-up mapped network, the structure exhibiting auxetic, zero Poisson's ratio, or little transverse deformation under an axial strain.
