The present disclosure relates to a trap device for a powder coating apparatus. The trap device includes a body part including an inlet through which exhaust gas containing lost powder is introduced, an outlet through which the exhaust gas is discharged, and an interior space in communication with the inlet and the outlet and a trap part that is located in the interior space of the body part and that traps the lost powder contained in the exhaust gas by a magnetic force.

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.
