Abstract: A method for determining antifouling ability of a material surface includes: (a) providing a determining device, wherein the determining device includes: a probe, wherein the probe includes a micro particle or a micro particle and a pollutant fixed on a surface of the micro particle; and a determining unit with a spring characteristic structure, wherein the probe is fixed at one end of the spring characteristic structure; (b) contacting the probe with a material surface-to-be-determined to make the micro particle itself or the pollutant on the surface of the micro particle adhere to the material surface-to-be-determined; (c) deforming the spring characteristic structure until the probe departs from the material surface-to-be-determined to recover the spring characteristic structure, and determining the level of the deformation; (d) determining the adhesion value of the probe to the material surface-to-be-determined using the deformation; and (e) determining the antifouling ability of the material surface.

Abstract: A solid surface wettability determination method is disclosed. A liquid is sprayed on a surface of an object. A light beam is projected toward the surface, wherein the light beam is reflected by the liquid on the surface to generate a reflected light. The reflected light is received by an optical detector, and the optical detector outputs a determining signal related to a wettability of the surface according to the reflected light. A corresponding signal-angle relation is selected from a database according to type of the liquid and material of the object. The contact angle of the liquid on the surface is obtained by applying the determining signal to the corresponding signal-angle relation.

Abstract: The filtration material includes a supporting layer, a first selective layer disposed on the supporting layer, and a second selective layer disposed on the first selective layer. The first selective layer includes a polyimide and an ionic polymer intertwined with the polyimide. In particular, the polyimide includes at least one repeat unit having a structure represented by Formula (I) wherein A1 is A2 is R1 and R2 are independently —H, —CF3, —OH, —Br, —Cl, —F, C1-6 alkyl group, or C1-6 alkoxy group; and X and Y are independently single bond, —O—, —CH2—, —C(CH3)2—, or —NH—.
