Abstract
A material is provided having a lamellar, non-centrosymmetric macroscopic structure, essentially consisting of a mixture of at least two populations of objects that are heterogeneous in blocks along an axis, each object consisting of at least two blocks, characterized in that each of the objects is connected to adjacent objects via interactions that involve at least two mutually incompatible blocks of the object and two blocks that are compatible one-to-one with the first of the blocks, and mutually incompatible along the chain of each one of said adjacent objects. The objects can be, in particular, block co-oligomers or copolymers.
Claims25
A material exhibiting a macroscopic structure of lamellar and non-centrosymmetric type, comprising:
- a mixture of at least two populations of objects which are heterogeneous by blocks along an axis, each formed by a chain of at least two different blocks,
- wherein each of said objects is bonded to adjacent objects via interactions involving at least two blocks which are incompatible with one another of said object and two blocks which are compatible one to one with the first said blocks and incompatible with one another arranged along the chain of each said adjacent object,
- wherein said structure is formed by a juxtaposition of cyclic linear arrangement of chains of said blocks offset with respect to one another in the direction of said chains, and
- wherein each said object is bonded to each adjacent object in all the directions of the material, with the exception of the direction perpendicular to the lamellae, via interactions involving at least two blocks which are incompatible with one another of said object and two blocks which are compatible one to one with the first said blocks and incompatible with one another arranged along the chain of each said adjacent object.
