Characterization, orientation, and deformation behavior of the double gyroid phase in elastomeric triblock copolymers
Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, 1999.

Ceramic nanostructures for block copolymers
… focus of this thesis is on the oxidation of the double gyroid and ''inverse" double gyroid morphologies using either ozone/uv and oxygen plasma techniques. By transmission electron microscopy (TEM) and atomic force microscopy (AFM), it is shown that the PI can be preferentially removed by …

Block copolymer photonic crystals
… A copolymer forming the three dimensional double gyroid at optically relevant length scales and its reflective properties are presented as well. Experimental results document the initial observation of photonic optical properties related to the microstructure of a block copolymer. One …

Triply Periodic Minimal Surface Lattices for Mechanically Tuning Structures and Designing Multifunctional Devices
… fields, etc. I present a multifunctional double gyroid capacitor that is designed for three functions (1) load bearing, (2) energy storage, and (3) self-sensing deformations. To characterize the load bearing capabilities, I studied the mechanical properties of four elastomeric gyroid unit …

Controlling nanostructures of globular protein-polymer block copolymers in bulk solutions and in thin films
… segregating polymer block are found to form a double gyroid structure with Ia3d symmetry, as opposed to perforated lamellae of bioconjugates with a strongly segregating polymer block. Common phase behaviors are also revealed, including the order of lyotropic order-order transitions and a …

Self-Organized Nanostructures from Stimuli-Responsive Triblock Terpolymers
… such as tetragonally perforated lamellae and double gyroid morphologies, were generated. Selective crosslinking of the PB domains of the bulk structures followed by sonication-assisted dispersion in non-selective solvents allowed the preparation of well-defined nanostructures. Crosslinked …

Structured polymer thin films: self-assembly and forced-assembly
… and self-assembly process. The self-assembled double gyroid (DG) network structure is of interest because of its unique three-dimensional triply-continuous structure. Our investigation focused on examining the self-assembly behavior of acetyl-terminated DG-forming …
