Manipulated micro/nanostructures and properties of nanoconfined polymer films by controlling the solid-polymer melt interface physically or structurally. Material Structure/Property Characterizations Scattering methods under high temperatures or solvent environments with transmission or grazing-incidence geometries: X-ray Reflectivity (XR), Small-angle X-ray Scattering (SAXS), X-ray Diffraction (XRD) Surface/Interface Characterization Techniques: Ellipsometry, Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), Polarized Optical Microscopy (POM), Fourier Transform Infrared Spectroscopy (FTIR), Static/Dynamic Contact Angle Measurements. RESEARCH EXPERIENCE Summer program mentor-Garcia Center, Stony Brook Univ., Stony Brook, NY (USA) Jun.-Aug., 2014 Led the summer student research program as a mentor in Garcia center at the department of Materials Science, Stony Brook University Investigated the effect of Graphene/Graphene oxide as compatablizer in polymer blends. Coached 20 summer students for research and science. Research Assistant-MSE Department, Stony Brook Univ., Stony Brook, NY (USA) Sep., 2012 -Jun., 2014 Led a master thesis project on investigating the self-assembling of block copolymers (BCP) on surface and the effect of adsorbed polymeric layer on microdomain structure of BCP Co-led and conducted research on understanding the polymer adsorption behavior at the flat/planar solid surface/interface. Collaborated with multiple national labs for structure/property characterization instrumentations and experiments such as Grazing Incidence Small Angle X-ray Scattering (GISAXS), X-ray Reflectivity (XR), Neutron Reflectometry (NR).
- 2. Research Assistant-Polymer Department, Sichuan Univ., Chengdu, (China) Sep., 2011 -Jun., 2012 Worked on senior thesis project on fabrication and characterization of superhydrophobic polymer materials in a National Key Lab. Performed all the experimental process independently, including preparing solutions, spraying solution on substrates, characterizing samples with Water Contact Angle (WCA) measuring instrument and Scanning Electric Microscopy (SEM).
