There is provided the method of forming a thin film of vinylidene fluoride homopolymer of I-form crystal structure having functional group at its end which can be applied to various substrates, by relatively easy method (applying conditions, manner, etc.). The method is a method of forming a thin film of vinylidene fluoride homopolymer by applying, on a substrate, a vinylidene fluoride homopolymer which contains, at one end or both ends thereof, a moiety represented by the formula (1): —(R1)n—Y (1) wherein R1 is a divalent organic group but does not contain a structural unit of the vinylidene fluoride homopolymer; n is 0 or 1; Y is a functional group, and has from 3 to 100 repeat units of vinylidene fluoride, to form a thin film of vinylidene fluoride homopolymer comprising I-form crystal structure alone or as main component.
A method of forming a thin film of vinylidene fluoride homopolymer comprising I-form crystal structure alone or as main component, the method comprises applying, on a substrate, a vinylidene fluoride homopolymer which contains, at one end or both ends thereof, a moiety represented by the formula (1):
A laminated article which has, on a substrate, a self-organized thin film formed by using vinylidene fluoride homopolymers comprising I-form crystal structure alone or as main component and having a number average degree of polymerization of vinylidene fluoride homopolymer unit of 3 to 100.
A laminated article which has, on a substrate, a thin film formed by bonding of vinylidene fluoride homopolymers comprising I-form crystal structure alone or as main component and having a number average degree of polymerization of vinylidene fluoride homopolymer unit of 3 to 100.
A vinylidene fluoride homopolymer represented by the formula (IA-2):
A vinylidene fluoride homopolymer represented by the formula (IB-3):
