Title:
DENDRON-STRUCTURED NANO-COLUMN, METHOD FOR MANUFACTURING BIAXIAL FILM USING SAME, AND BIAXIAL FILM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/145507
Kind Code:
A1
Abstract:
The present invention relates to a dendron-structured nano-column, a method for manufacturing a biaxial film using same, and a biaxial film comprising same. The dendron-structured nano-column uses rod-shaped or disc-shaped dendrons, and is formed in nematic polymerizable mesogens by the stacking and self-assembly or the like of dendrons through the π-π bonding and hydrogen bonding between moieties of the respective dendrons. Thus, optical anisotropy at the molecular level is realized, and it is possible to manufacture a film having optical biaxial characteristics with excellent orientation at the molecular level and high transmittance.
