Document Type and Number:
Japanese Patent JP2015140645
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a road sign pole having antifouling properties effective against a hydrophilic pollutant.SOLUTION: In a road sign pole to which hydrophobic antifouling properties are imparted, a road sign pole surface, on which a ratio of a CF bond is increased by plasma treatment using fluorine-containing gases, is formed. Preferably, in the road sign pole, a F/C ratio of the road sign pole surface, on which the ratio of the CF bond is increased, is in the range of 0.6-2.0. More preferably, a contact angle of water on the road sign pole surface, on which the ratio of the CF bond is increased, is set to be 100° or more.
