“…As strong acids are pH-independent, their integration in a material can prevent its swelling even at low pH . Poly(sodium 4-styrenesulfonate) (PNaSS) is especially known for its ability to reduce the amount of potassium in the body [38], for its utilisation as ion exchange material [39], ion transport [40,41] and in proton conduction in fuel cell membranes [42].…”

Negatively Charged Porous Thin Film from ABA Triblock Copolymer Assembly

et al. 2018

The preparation of well-arranged nano-porous thin films from an ABA triblock copolymer of polystyrene- block -poly(sodium 4-styrenesulfonate)- block -polystyrene (PS-PNaSS-PS) is reported. This copolymer was self-assembled in a N , N -dimethylformamide (DMF)/water mixture and the resulting micellar solution was used to prepare thin films via the compact packing of the flower-like micelles using spin coating method. The films were characterized by several microscopy techniques such as TEM, AFM, and SEM. Permeation test was performed to highlight the interconnected porous nature of the polymeric network obtained. Under applied water pressure, the micellar morphology was altered and a partial fusion of the micelles was observed that resulted in a change in the water permeability. Such hydrophilic nanoporous thin films with negatively charged interface could find applications in membrane filtration.

“…1). 34,[50][51][52][53] These monomers have been polymerised via RAFT [54][55][56] using an azide-functionalised CTA, which to the best of our knowledge, is the rst report of not only radical, but also controlled radical polymerisation of 2, 4, 5 and 6. It should be noted that photochemically-initiated radical polymerisation of 3, 52 and NMP, 57-59 ATRP [34][35][36][37] and RAFT 60 of 7 have been reported.…”

Design, synthesis and thermal behaviour of a series of well-defined clickable and triggerable sulfonate polymers

et al. 2015

In the printing industry, the exploitation of triggerable materials that can have their surface properties altered on application of a post-deposition external stimulus has been crucial for the production of robust layers and patterns. To this end, herein, a series of clickable poly(R-alkyl p-styrene sulfonate) homopolymers, with systematically varied thermally-labile protecting groups, has been synthesised via reversible addition-fragmentation chain transfer (RAFT) polymerisation. The polymer range has been designed to offer varied post-deposition thermal treatment to switch them from hydrophobic to hydrophilic. Suitable RAFT conditions have been identified to produce well-defined homopolymers (Đ, M w /M n < 1.11 in all cases) at high monomer conversions (>80% for all but one monomer) with controllable molar mass. Poly(p-styrene sulfonate) with an isobutyl protecting group has been shown to be the most readily thermolysed polymer that remains stable at room temperature, and was thus investigated further by incorporation into a diblock copolymer, P3HT-b-PiBSS, by click chemistry. The strategy for preparation of thermal modifiable block copolymers exploiting R-protected p-styrene sulfonates and azide-alkyne click chemistry presented herein allows the design of new, roll-to-roll processable materials for potential application in the printing industry, particularly organic electronics.
