Ionic Dendrimers Star-Burst Polyelectrolytes

The conformations of charged (regular) star-burst polymers (flexible ionic dendrimers), were analyzed theoretically in [33]. Referring to Fig. 4a, relevant architectural parameters for a star-burst polymer are the number of generations. [Pg.20]

counterion localization occurs when the number of generations in the star-burst polymer, g log2(Af/n), reaches some characteristic value, which is controlled by the same combination of the parameters, as for a PE star. [Pg.21]

Note that this combination is independent of the spacer length, n. [Pg.21]

2 Randomly Branched Poly electrolytes and Charged Fractals [Pg.21]

These results have been generalized further in [31], for charged polymeric fractals with arbitrary connectivity characterized by spectral dimension, d, (the latter relates the longest path in the fractal, / max - aN /, to its mass -- N) and arbitrary fractal dimension df (in the absence of ionic charges) in d-dimensional space. For ideal (Gaussian) fractals df = 2ds/ (2 - ds). For charged fractals [Pg.22]
