| 摘要 |
A method includes providing a first precursor on a first substrate; providing a second precursor on a second substrate; contacting the first precursor and the second precursor; reacting the first precursor and the second precursor to form a chemical reaction product; and moving the first substrate and the second substrate relative to one another to separate the chemical reaction product from at least one member selected from the group consisting of the first substrate and the second substrate, characterized in that, to control formation of a segregated phase domain structure within the chemical reaction product, a constituent of at least one member selected from the group consisting of the first precursor and the second precursor is provided in a quantity that substantially regularly periodically varies from a mean quantity with regard to basal spatial location.
