Abstract
The aim of this research is to prepare ultrahidrophobic surface on Dendrocalamus asper bamboo by using hydrothermal method. The ultrahydrophobic surface formation was carried out in two stages: TiO2 layer making on the bamboo surface and the formation of ultrahydrophobic surfaces on TiO2 coated bamboo using of octa fluoro 1-pentanol (OFP) as surface modifier. The ultrahydrophobic surface is made by using the volume (mL) ratio of OFP and isopropanol solvent 5:20 (BT-OFP5); 10:15 (BT-OFP10); 15: 10 (BT-OFP15); 20: 5 (BT-OFP5). The result of the measurement of contact angle shows the best volume ratio between OFP and isopropanol is 10:15 (BT-OFP10) with the contact angle is 1230. The result obtained was characterized using X-Ray Diffraction (XRD) which showed that anatase crystalline phase of TiO2 was formed on bamboo. The Scanning Electron Microscopy (SEM) analysis shows the morphology of TiO2 on the bamboo surface is spherical with the average particle size of 1.6 μm. In addition, mechanical and chemical tests, self-cleaning tests, and flammability tests are also performed. The result shows that ultrahydrophobic surfaces were successfully constructed with good mechanical properties, self-cleaning properties, and flame retardancy. Keywords: Indonesian bamboo, self cleaning, ultrahydrophobic surface, anatase TiO2, hydrothermal
