Allegra Liberman-Martin Ph.D. | Side Chain Design in Brush Block Copolymer Photonic Crystals
Major advances have been made in the preparation of mixed matrix membranes with embedded polymeric particles. One such advance combines the durability of polyvinylidene fluoride with the diverse functionality of hydrophilic polymers. Essential to the preparation of these membranes is the in-situ synthesis of microgel particles in the membrane casting solution. While performance and stability of these membranes have been well documented, probing and understanding the structure-function relationship has proven to be challenging. To address this challenge, we developed a new method using ultra-small angle neutron scattering (USANS) to measure microstructure formation in membrane casting solutions. Traditionally, USANS is applied to equilibrated systems, but in our experiment, we were able to measure transient structural changes during microgel particle growth. Our new approach using USANS will not only enable in-depth structural analysis of membrane casting solutions, but will also enable the study of many systems containing transient microstructure.
