Polymer-like structures

A key feature of electrolyte systems is their tendency to associate. Figure 6 shows several clusters from a simulation of the X = 0.1 system in a box of size L = 55 SitT = 0.03. The instantaneous density is p = 0.00122. As shown in the hgure, ions form polymer-like structures whose shapes include chains, rings, and branched chains. This pronounced tendency to cluster can be rationalized by considering a simple aggregate of only four ions. Figure 7 shows the fraction of ions involved in clusters of a given size n, for X = 0.1, at r = 0.03 and (p > = 0.003 (for comparison, we also show results for the RPM model at a similar density). The cluster size distribution exhibits an... 

Dense PLC networks (thermosets) are often prepared from mixtures of mono- and bifunctional monomers resulting in a one-comb polymer-like structure with crosslinks.

The tetrahedral arrangement of atoms in silica lends itself to the formation of a three-dimensional network, which makes up the polymer-like structure of a glass. Glass can be formed from a single oxide or a mixture of oxides. Silicon dioxide is the premier glassforming oxide either by itself or with other oxides. Additives to silica can either enter into...

Interestingly, the assembly of NRs in ID polymer-like structures can also occur in such a manner that their long axis is perpendicular to the chain direction. This process resembles the... 

Figure 2 Assembly of gold NRs in linear polymer-like structures by electrostatic interactions and hydrogen bonding, (a) Molecular structures of glutathione, cysteine, and CTAB. (b) Schematic of the assembly process, (c) TEM image of the chain formed by gold NRs end-capped with glutathione. The sample for TEM observation was prepared with glutathione concentration at 150 mM. The concentration of the NRs in the solution is estimated to be 0.6 nM. Zhang, S. Kou, X. Yang, Z. etal. Chem. Commun. 2007,1816-1818. Reproduced by permission of The Royal Society of Chemistry.
