Abstract
The present invention relates to a process for controlling the period characterizing the morphology obtained from a blend of block copolymers and of (co)polymers of one of the blocks on a surface employing a particular way of carrying out the synthesis of the blend of block copolymers and of (co)polymers of one of the blocks.
Claims21
A process for controlling the period characterizing the morphology obtained starting from a blend of block copolymers and of (co)polymers of one of the blocks in thin films, comprising the following stages:
- a) synthesizing the block copolymer so that the product of the synthesis comprises the said block copolymer and a (co)polymer of one of the blocks;
- b) depositing a solution of the blend of the block copolymer and of the (co)polymer on a surface;
- c) evaporating the solvent;
- and
- d) annealing.
