Understanding the formation of colloidal quasicrystals
Soft quasicrystals extend the length scale of quasicrystals from the atomic scale for metallic quasicrystals to the mesoscopic scale, and are interesting because the underlying principles governing quasicrystal formation might be much simpler to identify compared to metallic systems. We plan to study the formation of colloidal quasicrystals with Rheo-SANS using a Couette cell, where radial and tangential scattering patterns can be measured. Concentrated solutions of the block copolymers (PI-b-PS-OH, PI-b-PS-UPY) will be prepared in diethylphthalate d14. To measure the form factor in concentrated solution we will prepare samples in concentrated solution which contain different ratios of diethylphthalate d14 and diethylphthalate h14 (contrast variation). A concentration series from concentrated to dilute solution of the block copolymers (PI-b-PS-OH, PI-b-PS-UPY) will be prepared for the PI-PS system in diethylphthalate d14 (determining the ratio λ and determining the type of structure factor for the PI-PS system).
