Abstract
The present application relates to a block copolymer and uses thereof. The present application can provide a block copolymer—which exhibits an excellent self-assembling property and thus can be used effectively in a variety of applications—and uses thereof.
Claims15
A block copolymer comprising a first block and a second block different from the first block, wherein X of Equation 1below ranges from 2.5 to 10:
- X=1+(D×M)/(K×L) [Equation 1]
- where in the Equation 1, D represents a ratio (D2/D1) of a density (D2) of the second block to a density (D1) of the first block;
- M represents a ratio (M1/M2) of a molar mass (M1) of the first block to a molar mass (M2) of the second block;
- K represents a ratio (A2/A1) in a 1H-NMR spectrum of an area (A2) of a peak that is produced based on the second block to an area (A1) of a peak that is produced based on the first block;
- and
- L represents a ratio (H1/H2) of a number (H1) of hydrogen atoms in 1 mole of a repeat unit of the first block to a number (H2) of hydrogen atoms in 1 mole of a repeat unit of the second block,
- wherein the first block includes an aromatic structure that connects to a main chain of the first block by a linker and the linker is an oxygen atom, a sulfur atom, —S(═O)2—, a carbonyl group, an alkylene group, an alkenylene group, an alkynylene group,—C(═O)—X1—or —X1—C(═O)—, wherein the X1 represents an oxygen atom, a sulfur atom, —S(═O)2—, an alkylene group, an alkenylene group or an alkynylene group.
A block copolymer comprising a first block and a second block different from the first block, wherein X of Equation 1below ranges from 1.1 to 1.7:
- X=1+(D×M)/(K×L) [Equation 1]
- where in the Equation 1 , D represents a ratio (D2/D1) of a density (D2) of the second block to a density (D1) of the first block;
- M represents a ratio (M1/M2) of a molar mass (M1) of the first block to a molar mass (M2) of the second block;
- K represents a ratio (A2/A1) in a 1H-NMR spectrum of an area (A2) of a peak that is produced based on the second block to an area (A1) of a peak that is produced based on the first block;
- and
- L represents a ratio (H1/H2) of a number (H1) of hydrogen atoms in 1 mole of a repeat unit of the first block to a number (H2) of hydrogen atoms in 1 mole of a repeat unit of the second block,
- wherein the first block includes an aromatic structure that connects to a main chain of the first block by a linker and the linker is an oxygen atom, a sulfur atom, —S(═O)2—, a carbonyl group, an alkylene group, an alkenylene group, an alkynylene group, —C(═O)—X1—or —X1—C(═O)—, wherein the X1 represents an oxygen atom, a sulfur atom, —S(═O)2—, an alkylene group, an alkenylene group or an alkynylene group.
