New materials considering environmental problems
“Very low sliding angle” or “high water and oil repellent” material

Background and targets

• ●Wettability of solid surface has been evaluated by mainly measuring static contact angle. Recently, removal property tends to be attention but only not static property as repelling droplets. In other words, “dynamic property” will become more noticeable as one of the most important factors.
• ●KRI has proceeded to develop the three type of F-free water and oil repellent materials.
• ●Different types of water and oil repellent materials with property of “very low sliding angle” and “high oil repellent” have been developed for targets corresponding to usage environment and use.

Characteristic of the present technology

Proposal by KRI

Excellent slip property is effective for “improving energy efficiency” through decreasing interface sliding resistance but not only stain resistance, leading to solution of environment and energy problem. KRI will propose material development and their application corresponding to targets of various industry fields.

• ☆Functional analysis, degradation analysis of various water and oil repellent materials
• ☆Improving of various water and oil repellent materials
