Probing the Self-Organization Kinetics in Block Copolymer Films
نویسندگان
چکیده
Solvent annealing [1-3] has recently emerged as a powerful alternative to thermal annealing of block copolymer (BCP) thin films and nanocomposites. Taking a more general point of view, solvent treatment procedures, employing the selectivity of the solvents towards the different blocks, can produce new structures [4], and provide fascinating insights into the swelling kinetics and instabilities in such self-assembled and oriented thin films [5]. Taking a lamellar polystyrene-polybutadiene (PS-b-PB) film right from the spin coater into an in-situ vapor cell provided an intriguing trip through configuration space, with various lamellar re-orientations encountered during swelling.

Kinetics of directed self-assembly of block copolymers on chemically patterned substrates
Chemically patterned surfaces have been successfully employed to direct the kinetics of self-assembly of block copolymers into dense, periodic morphologies (”chemoepitaxy”). Significant efforts have been directed towards understanding the kinetics of structure formation and, particularly, the formation and annihilation of defects. In the present manuscript we use computer simulations of a soft,...
متن کاملRapid thermal processing of self-assembling block copolymer thin films.
Self-assembling block copolymers generate nanostructured patterns which are useful for a wide range of applications. In this paper we demonstrate the capability to control the morphology of the self-assembling process of PS-b-PMMA diblock copolymer thin films on unpatterned surfaces by means of fast thermal treatment performed in a rapid thermal processing machine. The methodology involves the ...

متن کاملSorption and Transport of Water Vapor in Amphiphilic Block Copolymer Films
Water vapor sorption in films consisting of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) amphiphilic block copolymers has been measured gravimetrically at air relative humidity in the range 38–94% at 248C. The water sorption isotherm was obtained and compared to data for water vapor desorption (drying) for the same system. The kinetics of water vapor sorption we...
متن کاملMillisecond Ordering of Block Copolymer Films via Photothermal Gradients.
For the promise of self-assembly to be realized, processing techniques must be developed that simultaneously enable control of the nanoscale morphology, rapid assembly, and, ideally, the ability to pattern the nanostructure. Here, we demonstrate how photothermal gradients can be used to control the ordering of block copolymer thin films. Highly localized laser heating leads to intense thermal g...
