Abstract
Block copolymers, thin films including block copolymers, and methods for forming block copolymers and thin films. The block copolymers, due to self-assembly or otherwise, may include one or more regions. The one or more regions may permit a thin film including a block copolymer to be used as a nanostructured membrane.
Claims20
A method for preparing a block copolymer (BCP), the method comprising:
- (i) providing a compound of formula (I)—
- wherein R1 is selected independently from a C1-C20 hydrocarbyl;
- (ii) providing a compound of formula (II)—
- wherein R2 is selected independently from a C1-C20 hydrocarbyl;
- (iii) contacting the compound of formula (I) and the compound of formula (II) to form an intermediate polymer;
- and
- (iv) contacting the intermediate polymer and vinylpyridine to form the block copolymer.
4 more elements
A block copolymer (BCP) having the following structure:
- wherein—
- R1 is selected independently from a C1-C20 hydrocarbyl,
- each R2 is selected independently from the group consisting of hydrogen and a C1-C20 hydrocarbyl,
- each X is selected independently from N or N+R3, wherein each R3 is selected independently from a C1-C20 hydrocarbyl, and
- m and n are selected independently from an integer from 1 to 10,000.
2 more elements
A method of forming a thin film of a self-assembled block copolymer, the method comprising:

- wherein—
- R1 is selected independently from a C1-C20 hydrocarbyl,
- R2 is selected independently from a C1-C20 hydrocarbyl,
- X is N, and
- m and n are selected independently from an integer from 1 to 10,000;
- and
- (ii) disposing the block copolymer on a substrate to form the thin film.
