Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

open access: yesAdvanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Instabilities during wetting processes: Wetting by tensioactive liquids

Journal of Colloid and Interface Science, 1988
Stick-slip phenomena may be observed when a liquid containing surface-active molecules advances on a hydrophilic solid surface. They are due to the diffusion of these molecules in front of the liquid edge, locally increasing the contact angle. This paper presents an experimental study of the instabilities of the liquid front.

The dynamics of wetting processes

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1994
Abstract The dynamic wetting and dewetting behaviour of polyethylene terephthalate (PET), studied by the Wilhelmy technique, is briefly reviewed. Slow relaxation effects were observed for PET surfaces. Equilibrium is achieved by an evaporative process in the case of advancing contact angles.
