Poly 4- styrenesulfone

The pyrogram of a sample of poly(4-styrenesulfonic acid) performed at 600° C in He and with the separation done on a Carbowax column (similar to other examples, e.g. polyethylene) is shown in Figure 6.6.3. The peak identification for the chromatogram shown in Figure 6.6.3 was done using MS spectral library searches and is given in Table 6.6.5.

A humidity-sensitive conducting polymer actuator made up of PEDOT doped with poly(4-styrenesulfonate) (PEDOT/PSS) was fabricated [47]. Water vapor sorption and electro-active actuating behavior of free-standing PEDOT/PSS films were investigated by sorption isotherm and electromechanical analyses. The non-porous PEDOT/PSS film, with a specific surface area of 0.13 m g sorbed water vapor of 1,080 cm (STP)g , corresponding to 87 wt%, at relative water...

Sharma et al. reported a novel and cost-effective fabrication of the CNT/ PPy nanocomposite on the poly(4-styrenesulfonic acid) (PSS)-dispersed MWNTs [79]. PSS not only stabilized the MWNT suspension but also provided charged groups to facilitate an ordered and uniform growth of pseudo-capacitive materials around the MWNTs through electrostatic attractions. The in situ oxidation of Py with KMnO yielded molecular-level dispersion of the MnO in PPy matrix that improved the electronic conductivity, mechanical stability, and pseudo-capacitance. The MWNT-PSS/PPy MnOj ternary nanocomposite exhibited a high SC of 268 F/g at 5 mV/s and only 7% faded in the specific capacity at 100 mV/s and 10% faded in the same after 5000 CV cycles (Figure 8.9). 

Figure 21.13 contains data for poly(4-styrenesulfonic acid) (PSSH). For this polymer, there is a significant (0.4 eV) offset A between the EvacS, both before and after exposure to the x-rays. This is a...

More and more research is being done on conjugated polymers (Chen and Lu, 2005), which display a certain level of conductivity. Some examples of them are polyaniline (Nohria et al., 2006 McGovern et al., 2005) and poly(3,4-ethylenedioxythiophene)— poly(4-styrenesulfonate) (PEDOT-PSS Daoud et al., 2005).

The electrode modified with a 3-mercaptopropionic acid (MPA) is dipped into a solution containing poly-L-lysine and poly(4-styrenesulfonate) to form a polyion complex on the electrode surface it is then necessary to dry it in air for 4 h and place it under vacuum. 

Planar and disposable reference electrodes have been described. The method is essentially the same as used for obtaining all-plastic ion-selective electrodes. Aqueous dispersion of poly(3,4-ethylenedioxythiophene) doped by poly(4-styrenesulfonate) ions (PEDOT-PSS, Baytron P).
