Cationic Microfibers

Che et al. 215) extended the assembly into aqueous environments, describing the preparation of supramolecular polyelectrolytes by self-organization of cationic organoplatinmn (II) complexes in water through extended Pt- Pt and hydrophobic interactions (Fig. 13). Aligned films and discrete uniaxial microfibers with cofacial molecular orientations were readily produced with these phosphorescent viscoelastic mesophases. 

Polyesters, such as PET, are now widely used in the manufacture of fibers for textiles and other apph-cations. While PET has many desirable properties that make it suitable for manufacturing fibers, there is a continuing need for polyester fibers that have improved properties, or properties that are different from PET, thereby opening new uses for polyester fibers. For example, PEN has found applications in high performance sailcloth materials or in industrial filtration applications. Microfibers can be obtained from fibers using a laser thinning method [98].
