Contact Angle of an Evaporating Droplet of Binary Solution on a Super Wetting Surface
Mengmeng Wu, Masao Doi, Xingkun Man
We study the dynamics of contact angle of a droplet of binary solution evaporating on a super wetting surface. Recent experiments show that although equilibrium contact angle of su…
Swelling Dynamics of a Disk-Shaped Gel
Xingkun Man, Masao Doi
When a gel absorbs solvent from surrounding, stress field is created in the gel, and this causes complex dynamics of the swelling behavior. Here we study this effect for disk-shape…
Defect removal by solvent vapor annealing in thin films of lamellar diblock copolymers
Xinpeng Xu, Xingkun Man, Masao Doi +2
Solvent vapor annealing (SVA) is known to be a simple, low-cost and highly efficient technique to produce defect-free diblock copolymer (BCP) thin films. Not only can the solvent w…
Effect of Sinusoidal Surface Roughness and Energy on the Orientation of Cylinder-Forming Block Copolymer Thin Films
Yanyan Zhu, Karim Aissou, David Andelman +1
We explore the relative stability of three possible orientations of cylinder-forming di-block copolymer on a sinusoidally corrugated substrate. The cylinders can be aligned either…
Multi-Ring Deposition Pattern of Drying Droplets
Mengmeng Wu, Xingkun Man, Masao Doi
We propose a theory for the multi-ring pattern of the deposits that are formed when droplets of suspension are dried on a substrate. Assuming a standard model for the stick-slip mo…
Orienting thin films of lamellar block copolymer: the combined effect of mobile ions and electric field
B. Zheng, X. -K. Man, Z. C. Ou-Yang +2
We study thin films of A/B diblock copolymer in a lamellar phase confined between two parallel plates (electrodes) that impose a constant voltage across the film. The weak-segregat…
