Hydrophobic surface on Indonesia bamboo timber has been successfully prepared using OFP (2,2,3,3,4,4,5,5-octafluoro-1-pentanol) as a modifier agent.  Hydrothermal  method  has been used to fabricate anatase TiO2 film followed by OFP modification. Maximal water contact angle of 123ο has been obtained for the composition of 10 mL OFP and 15 ml 2-propanol (B-T-OFP10). XRD analysis showed the existence of pure anatase TiO2 film on bamboo timber, confirmed by EDS result. SEM image of a TiO2-coated and a typical hydrophobic bamboo timber revealed irregular aggregates of TiO2 on the surface and covered surface with nanospheres, respectively. The optimum sample (B-T-OFP10) showed good mechanical stability, self-cleaning property and flame retardancy compared to pure bamboo timber.
