Protection complexes

Strandfoam cannot be produced with a varying cell axis direction. This means that it is unsuitable for curved products such as helmet liners, for which the high yield stress direction must vary in the product. In automobiles it is used for occupant protection complex shapes can be sawn from block, cut by abrasive wires, or thermoformed. 

All the compounds described in this chapter are well-defined supramolecular species, soluble in common solvents (e.g., CHjClj, CHjCN), and stable both in the dark and under light excitation. They carry an overall positive chaige that, except for the case of cyclometallated and protected complexes, is twice the number of the metal atoms. 

Another theory claims that a protective complex between the metal and the CP is formed in the metal-polymer interface. Kinlen et al. [73] found by electron spectroscopy chemical analysis (ESCA) that an iron-PANl complex in the intermediate layer between the steel surface and the polymer coating is formed. By isolating the complex, it was found that the complex has an oxidation potential 250 mV more positive than PANI. According to Kinlen et al. [73], this complex more readily reduces oxygen and produces a more efficient electrocatalyst. 

X-ray diffraction was also used to confirm the location of DNA within the supramolecular structure. The lamellar repeat period (d = 5.22 0.03 nm) and wide angle spacing (0.46 0.01) indicated the formation of ordered lamellar bilayers. These dimensions did not change upon addition of DNA (d = 5.31 0.14 and 0.46 0.01, respectively), which suggests that DNA was interacting with the liposome surface to form protective complexes, as opposed to being sandwiched between bilayers, which is often observed in lamellar lipoplexes. 

Another possible approach is based on cyclodextrins, which are bucket-shaped molecules composed of six to eight glucose units and are enzymatically derived from starch. They have the capability of building protective complexes with a variety of molecules, including cosmetically relevant ones such as menthol and vitamin E. These complexes can be attached to fabrics with the help of an adhesive or a binder, which includes cross-linkable silicones, polyacrylates, polyethylene-vinyl acetate, and polyurethanes. A certain amount of binder, typically 0.25-4.0% of dry matter per weight of fabric, is required to bind the microcapsules, complexes, or loaded particles effectively to the medical textile materials. 

Due to the fact that most polymerization reactions with early transition metal complexes contain an excess of aluminum alkyl reagents compared to the functional group, a protective complexation of the amine by the aluminum alkyl is likely. Hence, these reports will be disregarded here and are discussed in Section 3.24.3.3.2(i).
