Dynamic process of water sorption in a thermoplastic modified epoxy resin system

Article Abstract:

The dynamic water sorption processes in the series of poly(ether imide) (PEI) modified diglycidyl ether bisphenol A/(4,4'-diaminodiphenyl)sulfone (DGEBA/DDS) systems are investigated. The delicate relationship between dynamic water sorption behavior and the morphology resulting from the phase separation are discussed with the help of scanning electron microscopy.

Surface-induced phase transition of asymmetric diblock copolymer in selective solvents

Article Abstract:

An investigation on the surface-induced phase transition of asymmetric diblock copolymer in selective solvents is conducted using the real-space version of self-consistent field theory (SCFT). Results reveal that in a very dilute block copolymer solution, phase separation could be induced through polymer depletion as the solution becomes more confined.

Depletion effect on supermolecular assembly: a control of geometry of adsorbed molecules

Article Abstract:

An investigation regarding controlling the optimal geometrical arrangement for the adsorbed molecules by depletion interaction between the adsorbent and the metal wall is described. The surface enhanced Raman scattering (SERS) spectroscopy is used to investigate the adsorbed molecules.
