Abstract: A surface coating material includes a first material and a second material having a different structure. The first material includes a linking group represented by *—(CF2)nO—* between two terminal ends, where one terminal end is a trifluoroalkoxy group and another terminal end is a silane group. The second material includes an oxyalkylene group or a *—NH—* linking group between two terminal ends, where one terminal end is an alkoxy group or an amino group, and another terminal end is a silane group. The first material is included in the surface coating material in an amount of less than or equal to about 5 mol % relative to a total amount (100 mol %) of the first material and the second material in the surface coating material.
