The present invention discloses a block copolymer comprising at least a block A and a block B, wherein the monomer of block A contains one or more of the structural units:
a C3-C6 alkenyl group containing a substituent or a C3-C6 alkenyl group; wherein the number of R
1
is 0, 1, 2, 3, 4 or 5; R
2
is selected from the group consisting of: absent, substituted or unsubstituted C1-C6 alkyl, substituted or unsubstituted C1-C6 alkoxyl, hydroxyl, halogen; “substituted” means a group is substituted by one or more substituents selected from halogen and hydroxyl; block B is obtained by polymerization of the monomer
R
6
is selected from F or a group containing F, and the number of R
6
is 0, 1, 2, 3, 4 or 5. The block copolymer can assemble rapidly at a low temperature with self-repairing performance to reduce the defect rate.
