Dehydrogenated tallow

Electroluminescence from clay/polymer intercalation compound has been reported (287). Electroluminescent poly[2-methoxy-5-(2 -ethyl-hydroxy)-1,4-phenylenevinylene] was complexed with dimethyl dehydrogenated-tallow ammo-nium-montmorillonite. The product was fabricated as thin films by spin coating the suspension on ffO-coated glass substrate and subsequent deposition of A1 on the films as cathodes. Complexation with clay led to improved photostability and photoluminescence output. The absorption characteristics of dyes also have been utilized to prepare clay-dye hybrids as possible ultraviolet radiation collectors (288-290). 

The nanoclay, chemically modified with a dimethyl dehydrogenated tallow quaternary ammonium cation, was Closite 15A provided by Nanokor Co., Ltd. The density and layer distance of clay were 1.6g/cm and 30.3 A, respectively.

In order to improve the rheological properties of LCP polymers, the availability of nanocomposites could be a viable solution to prepare foams with good morphologies. MMT nanoparticles were used to prepare LCP nanocomposites by Bandyopadhyay et al. who experienced a significative increase in the rheological properties through the addition of 3.4% of dimethyl dehydrogenated tallow quaternary ammonium-modified MMT (Bandyopadhyay, Sinha Ray, and Bousmina, 2007, 2008).

The dimension stability of nanocomposites was studied by Zeng and Lee. Figure 5.14 shows the shape changes of injection molded PS and PS/clay nanocomposites under the aforementioned thermal cycle (50°C, 1 h 75°C, 1 h 105 C, 1 h and 135°C, 1 h). The original sample shape is shown in the first row. Pure PS and the extmded PS/20A (dimethyl dehydrogenated tallow ammonium...
