Figure 7.13 (a) Schematic representation of the formation of a nanofibrillar network in a PS matrix, (b) AFM topography (top) and phase (bottom) images of a P3HT/PS (5/95) blend spin cast from CH2CI2 top surface (left),... 

Fig. 15. Specimen from an HDPEA LDPE blend for in situ sfm deformation test with an evaporated pattern to observe an area of interest (a, b) optical micrographs (c) sfm phase signal image in tapping mode. From Reference 48.

Figure 18.7 PCA results obtained for the computer-simulated PMMA-PEMA polymer blend image, after Poisson scaling, (a) Loadings on PCA factor 1. PCA successfully distinguishes the two chemical phases. Positive peaks are...

Figure 4.12. A sample holder for combined AFM and TEM microtomy is shown (A) with a central inner part that can be used for AFM. Micrographs taken of an s-PP/PEB blend in a phase AFM image (B) is compared with a TEM image of a RUO4 stained section from the same sample (C). (From Thomann et al. [153], (1999) Blackwell Publisher used with permission.)...

Figure 5.72. Atomic force microscopy images (5 x 5fan) of ternary blends (A) topographic and (C) phase contrast images of PA 6/EPR-g-MA/IA (B) topographic and (D) phase contrast image of PA 6/SEBS-g-MA/IA. (From Radovanovic et al. [357], (2004) Elsevier used with permission.)...

Figure 5.76. Height (left) and phase (right) images (5pm on a side) of a thermoplastic vulcanizate made by mixing EPDM, iPP, and carbon black show the detailed morphology of these complex blends. (From Magonov and Yerina [253], (2005) Springer used with permission.) (See color insert.)...

Figure 11.20 shows the SEM image of the morphology of 30/70 nylon-EPR blends at two different compatibilizer concentrations. It is apparent that the addition of compatibilizer significantly reduces the size of the dispersed phase. The addition of 10% compatibilizer is sufficient to... 

FIGURE 20.4 (a, b) Height and phase images of rubber blend of natural rubber (NR) and butylene rubber (BR) (50 50), which were taken immediately after cryo-ultramicrotomy. (c, d) Height and phase images of the same sample location as in (a, b) taken 12 h later. 

FIGURE 20.12 (a) Top part shows variations of elastic modulus profile measured in different locations of the polypropylene (PP)-ethylene-propylene-diene terpolymer (EPDM) blend. The locations are shown by white dots in the blend phase image placed at the bottom. Vertical white dashed lines show the components borders and the elastic modulus value for this location. Vertical black dotted lines indicate the locations where elastic modulus E gradually changes between PP (E ) and EPDM (E )- These values are indicated with black arrows on the E axis, (b) LvP curves for PP-matrix, EPDM-domains, and one of interface locations. The approach curves are seen as solid black lines and the retract curves as gray lines. 

FIGURE 20.14 (a) Height image of a cluster of carbon black (CB) particles. The sample was prepared by pressing the particles into a pellet, (b) Optical micrograph of a cryo-ultramicrotome cut of a mbbery composite loaded with silica, (c, d) Phase images of a nanocomposite of polyurethane (PU) loaded with silica and a mbber blend based on natural mbber (NR) and styrene-butadiene copolymer (SBR) loaded with siUca, respectively. The samples were prepared with a cryo-ultramicrotome.
