Block copolymers ordering

Blockcopolymer microphase separation [9] Depending on the length of chemically different blocks of monomers in a block copolymer, ordered nanostructures can be obtained in bulk samples and thin films. The film morphology can differ significantly from the bulk morphology, but because the structure is determined by the pair-pair interaction of monomers and/or an interface, and it is a thermodynamically stable structure, it is classified as self-assembly. [Pg.188]

The most profitable methods to study the block copolymers ordered structures are X-ray diffraction and electron microscopy. But differential scanning calorimetry, polarization microscopy, dilatometry, infrared spectroscopy and circular dichroism... [Pg.89]

Fig. 26. Profiles of the block copolymer order parameter pA-pB (pA(z)> Pb(z) are densities of A-monomers or B-monomers at distance z from the left wall), plotted for the thicknesses D=14(a), 20(b), 24(c) and 30(d). Temperatures are (in units of AB/kB) 1/T=0.3 (circles), 0.4 (diamonds), 0.5 (triangles) and 0.6 (squares). From Kikuchi and Binder [35]... Fig. 26.

Similar examples that show the fruitful interplay between simulation, analytical theory, and experiments can be given for spinodal decomposi-tion, ° surface enrichment and wetting, block copolymer ordering,etc. Some of this material will be discussed in later sections. [Pg.362]

At present, there is no comprehensive theory that can enable one to predict the rheological behavior of a block copolymer, ordered or disordered, in terms of its molecular parameters. It can easily be surmised that prediction of the rheological properties of a block copolymer in the ordered state would be a difficult task, because the type of microdomain structure (spheres, cylinders, gyroids, or lamellae) must be incorporated into the development of a molecular theory. It should be pointed out that spherical... [Pg.363]
