Nylons sectioned micrographs

Fig. 12.15. Scanning electron micrographs of (a) trilobal-shaped spinerette, and (b) resulting cross-sections of nylon fibers. The pictures were taken at different magnifications. (Courtesy BASF Corporation)...

Figure 3. Optical micrograph of sections through a doubly oriented nylon 66 rod taken (A) perpendicular to the roll direction, (001) of Figure 2 (B) parallel to the roll direction, (010) of Figure 2 and (C) transverse to the rolling plane, (100) of Figure 2.

Fig. 17.24 TEM micrographs of nylon 6/organoclay/EOR-g-MA (76/4/20) ternary nanocomposite showing (a) submicron and nano-voids which are associated with intra-gallery delamination of some organoclay layers (note that the section is not selectively stained in order to clearly reveal delaminations of clay layers), (b) cavitation of EOR-g-MA particles which preferentially starts from the larger particles as indicated by arrows, and (c) extensive matrix shear yielding at the arrested crack tip which in turn causes the EOR-g-MA particles and delaminated clay layers to collapse within the matrix. A schematic of the arrested crack tip illustrating different locations from where TEM micrographs (a-c) were taken is also shown. Note that the schematic is not to scale (Lim et al. 2010)...

Figure 13.8 SEM micrograph of polished cross section of 40 wt% aminosilane-treated 0.8pm calcined kaolin in nylon 6,6.

Fig. 4.9 Two examples of microtomed sections viewed in the optical microscope are shown (A) a section of a nylon pellet, in polarized light, reveals a coarse spherulitic texture and (B) a section from a black, molded nylon part, in a bright field micrograph, shows the size and distribution of the carbon black filler.

Fig. 5.42 Polarized light micrographs of a molded nylon cross section show a nonspherulitic skin (top in A) and rounded isolated spherulites in the transition zone. A classical Maltese cross extinction pattern is observed with black brushes showing the radial texture within the spherulites (B). (See also Fig. 1.3 in color section.)...

Figure 5.109. Transmission electron microscopy micrographs of cryomicrotomed sections of a nylon/clay nanocomposite produced by continuous chaotic blending forms layers of oriented platelets and matrix polymer. (From Zumbrunnen et al. [502, 503] used with permission of the Society of Plastics...
