Interface stability, morphological

The best results were obtained by using the block copolymer surfactant SE3030 together with the nonionic initiator PEGA200 which supports interface stabilization and improves the structural perfection (Fig. 18a) of the polystyrene capsule morphology. 

First, the copolymer is automatically formed at the interface between the two immiscible polymers where it is needed to stabilize morphology. In contrast, when a compatibilizing copolymer is added as a separate entity to a polymer blend, it must diffuse to the polymer-polymer interface to be effective for promoting morphology stabilization and interphase adhesion. However, the added copolymer may prefer to form micelles as a separate phase that is useless for compatibilization. 

Metal UPD at the SAM/substrate interface is of interest for several reasons. Firstly, from an application point of view as the intercalation of another metal alters the thiol-substrate bond and, thus, the stability of a SAM that can be exploited to generate heterogeneous and patterned SAMs, a point we will return to later. Secondly, the intercalation and alteration of the thiol-substrate bond changes the morphology of a... 

If we predict morphological changes based on the analyses of interface states, on the R versus A/u/kT relations for the three models of growth mechanism, and on the morphological stability of interfaces, as discussed in Sections 3.2-3.9,... 

Another solid state reaction problem to be mentioned here is the stability of boundaries and boundary conditions. Except for the case of homogeneous reactions in infinite systems, the course of a reaction will also be determined by the state of the boundaries (surfaces, solid-solid interfaces, and other phase boundaries). In reacting systems, these boundaries are normally moving in space and their geometrical form is often morphologically unstable. This instability (which determines the boundary conditions of the kinetic differential equations) adds appreciably to the complexity of many solid state processes and will be discussed later in a chapter of its own.
