Recently, the demand for lightweight materials is increasing rapidly to reduce carbon emissions. Carbon fiber reinforced thermoplastic polymer (CFRTP) is attracting attention from the industry due to its many advantages as a recyclable light weight material. However, polyamide 6-based CFRTP, a representative thermoplastic CFRTP, shows some disadvantages such as decrease in mechanical properties and increased contamination due to its hydrophilicity and high surface energy. In this study, we fabricated the CFRTP by thermoplastic reactive resin transfer molding (T-RTM) process, and then fluorinated polydopamine was coated to improve surface properties. The morphology of the surface and surface elements were analyzed, and it was confirmed that the surface was modifed to be hydrophobic. In addition, water absorption and surface energy of CFRTP were reduced remarkably, and it is expected that CFRTP can be applied in various environments with humidity.
