Method for evaluating quality of liquid repellent film

摘要

The present invention relates to a method for evaluating a liquid repellent film on parts subjected to liquid repellent treatment, particularly to a method for evaluating the quality of a liquid repellent film comprising a substance absorbing or emitting electromagnetic waves, wherein the transmittance or reflectance ratio of electromagnetic waves, or fluorescence intensity is measured, and the characteristics of the liquid repellent film is evaluated from the graph of the relationship between a film thickness and a contact angle with a liquid having been determined in advance.
