Phase transitions of the PS-fo-PI system have been extensively studied. The morphological transition from the I phase to the G phase proceeds through nucleation and growth. The difference in the geometrical characteristics of these two phases induces considerable local distortion of both morphologies... [Pg.193]

Court and Hashimoto [186] investigated morphological transitions triggered by blending two block copolymers with different volume fractions. [Pg.210]

An indication of such a morphological transition is a pronounced enhancement of oxide film roughness at a thickness of 11 nm, observed by AFM, as shown in Fig. 5.5. The appearance of this surface ripple corresponds to the first potential peak in Fig. 5.4. An investigation using differential IR spectroscopy revealed that the peak position, width and degree of symmetry of the Si-O absorption bands... [Pg.84]

Proton conductivities of 0.1 S cm at high excess water contents in current PEMs stem from the concerted effect of a high concentration of free protons, high liquid-like proton mobility, and a well-connected cluster network of hydrated pathways. i i i i Correspondingly, the detrimental effects of membrane dehydration are multifold. It triggers morphological transitions that have been studied recently in experiment and theory.2 .i29.i ,i62 water contents below the percolation threshold, the well-hydrated pathways cease to span the complete sample, and poorly hydrated channels control the overall transports ll Moreover, the structure of water and the molecular mechanisms of proton transport change at low water contents. [Pg.381]

The benefits of utihzing combinatorial methods for investigating polymer properties have been outlined recently [19,166,167]. Polymer gradient brush assemblies are expected to play an active role in further combinatorial material effort. Possible areas of interest include (but are not hmited to) study of phase behavior (stability) in hquid [168] and polymer blend [169] systems, morphological transitions in block copolymers [170,171], cell culturing [58,172], and others. [Pg.117]

For the most part, even qualitative relationships between such structural considerations and film properties are lacking. Recently, however, two important correlations have been presented Device quality a-Si contains only monohydride bonding structures (207), and the intrinsic film stress rises drastically as a morphological transition from columnar to noncolumnar growth occurs (210). Both studies point to the importance of defects in a-Si, although the precise role of these defects is still unclear. [Pg.435]
