Figure 14.10 TEM image of blend containing 75 wt. % of a SBT triblock copolymer and 25 wt. % st diblock co-polymer. The non-centrosymmetric supramolecular structure of this blend is schematically illustrated in the diagram that assigns the different phases observed in the marked part of the micrograph (Copyright Wiley-VCH Verlag GmbH Co.

TEM images of blends of S-B(h)-S with S/DPE(15) and S/DPE(30) are shown in Figure 25.16. The largest particles are about 1 p.m, which seems promising for toughening. Within the particles the typical lamellar structure of block copolymers can be seen. The white lines are the unstained hydrogenated butadiene and the dark regions the stained polystyrene phases. 

In Figure 6, PL spectra and images of blended films with different relative donor/acceptor concentrations, spin-coated on quartz substrates, are reported. It is seen that enhancing the concentration of STO a broad red-shifted emission due to exciplex states appears, in addition to the blue emission due to TPD, which is responsible for the white emission within a concentration range 17-53% of STO in TPD. The normalized EL spectra were similar to the PL spectra for the concentration used (20%), showing that the shape of the low-energy exciplex spectrum is almost independent of the applied voltage. The CIE coordinates of the EL spectra indicated a balanced white emission (0.39, 0.40) (Mazzeo et al., 2003 b).

Fig. 2 Scanning confocal microscopy images of blend films of ultra-high-molecular-weight polyethylene and 10 wt% EHO-OPPE (see Fig. 1). (a) As prepared film, (b) Uniaxially deformed sample drawn to a draw ratio of 80. Both images were acquired by detecting the polarization direction oriented parallel to the (eventual) deformation direction. Inset shows images acquired by detecting the orthogonal polarization direction. Adapted with permission from [35]. Copyright 2000 American Chemical Society...

The morphological investigation of NBR/NR filled with different silica loadings was carried out by AFM and TEM. The images of blends with different ratio r are presented in Figure 6.8 and support very well the silica localization shown in Figure 6.7(a).
