    Asian Institute of Technology Bangkok Thailand Master s thesis title Studies on superhydrophobic surfaces of zinc oxide nanorods grown on artificially ink jetted microstructures Thesis short Summary The surface that cannot mostly attach the water is called hydrophobic We can determine the level of hydrophobicity with water contact angle WCA Surface geometry is the important mechanism of the superhydrophobic property Attempts have been mostly made in the literature to construct structures similar to the lotus leaves by photolithography and etching of silicon substrates Here we report on the use of ink jetting technique to construct the templates for the growth of microbumps consisting of zinc oxide ZnO nanorods diameter 100µm using a simple hydrothermal growth on seeded substrates Several patterns were developed and it was found that 100µm bumps separated from one another by about 100µm consisting of ZnO nanorods of at least 4µm height leads to water contact angle of 143 This can be further improved by a simple fluorosiloxane treatment to about 150 contact angle Continuous coatings of nanorods without microbumps yielded hydrophilic surfaces with water contact angle 10 December 1999 November 2003 B E Electrical communication Electrical communication and Information Technology Mandalay Technological University Mandalay Myanmar Bachelors Research Project title Computerized control home security system Employment background May 2008 December 2009 Position Research Associate Employer Center of Excellence in Nanotechnology Asian Institute of Technology Location Bangkok Thailand Job description Research on nanoparticles and their applications Research Interests 1 Wetting nature hydrophobic and hydrophilic of surfaces 2 Electronic device fabrication using nanomaterials 3 Fabrication of self organized nanoporous membrane 4 Sensors for monitoring the environment 5 Carbon nanotube for electronics 6 Desalination List of publications Rungrot Kitsomboonloha Sunandan Baruah Myo Tay Zar Myint Vivek Subramanian Joydeep Dutta Selective growth of zinc oxide nanorods on inkjet printed seed patterns
