Advisor: Thomas P. RussellThesis: Architecture-directed Interfacial Assemblies of Block Copolymers• Developed quantitative methods to monitor the kinetics of in-situ reaction of block copolymers upon conversion at the water-oil interface using real-time interfacial tensiometry.• Developed star block copolymer and random bottlebrush copolymer as an efficient compatibilizer to promote adhesion, with in-depth investigation on the interfacial conformation and the architecture confinements.• Revealed architecture dependence on the orientation of star and bottlebrush block copolymer in thin films, which enables applying block copolymer for nanotemplate and nanolithography.• Developed large-scale nano porous films through the interfacial assembly of star block copolymer at fluids interfaceSkills: X-ray/Neutron Scattering · X-ray/Neutron Reflectometry · Ellipsometry · Light Scattering · Atomic Force Microscope · Fluorescence Microscope · Scanning Electron Microscopy (SEM) · Transmission Electron Microscopy (TEM) · Optical Microscopy · Wafer Cleaning · UV Ozone · Spin Coating · Contact Angle · Pendant Drop Tensiometry · Origin (Software) · Microsoft Excel · Polyphenol and Polydopamine Synthesis · Mass Spectrometry · X-ray photoelectron spectroscopy (XPS) · IR Spectroscopy · ATR-FTIR · GPC · Thermogravimetric Analysis (TGA) · Differential Scanning Calorimetry (DSC) · KLA Filmetrics F20 · IGOR Pro · SAXS · Powder X-ray Diffraction · Laser Cutting · 3-D Printing · Compression Molding · Asymmetric Double Cantilever Beam (ADCB) test · Bending Modulus Measurements
