摘要： A method of measuring a friction coefficient of a surface of a specimen includes: obtaining surface information of the specimen by using an atomic force microscope (AFM); calculating data of a friction coefficient of the surface of the specimen by using the surface information of the specimen; and mapping the data of the friction coefficient of the specimen to an image. The method of measuring a friction coefficient of a surface of a specimen may prevent a probe part of an atomic force microscope from being worn out and secure high reliability of the friction coefficient value by correcting the atomic force microscope using a specimen to be actually measured and measuring a fiction coefficient at the same time.
