摘要： A method is provided for removing a residue from a surface. The method includes steps of applying a cleaning medium to the surface containing the residue. The cleaning medium comprises up to 100 wt. % of at least a solvent. Allowing the cleaning medium to be in contact with the residue for at least 5 seconds to swell/dissolve the residue for removing the residue from the surface. At least 50 wt. % of the residue and the cleaning medium are removed from the surface by wiping the surface with a shear force. The residue contains a sulfonated polymer having an ion exchange capacity (IEC) of greater than 0.5 meq/g. The sulfonated polymer can kill >90% of microbes coming in contact with the sulfonated polymer in less than 30 min.

摘要： A polyelectrolyte composition is disclosed comprising (a) a polyionic multiblock polymer (PILSBC) comprising a styrenic block copolymer (SBC) precursor having at least a quaternary ammonium salt; (b) a cross-linking agent comprising a compound having at least two amino groups; (c) a lithium salt; and (d) an ionic liquid. The SBC precursor comprises at least a block D derived from a substituted vinyl aromatic monomer; a block A derived from a vinyl aromatic monomer; and optionally a block B derived from a conjugated diene monomer. The polyelectrolyte composition has a mol ratio of the ionic liquid to the quaternary ammonium salt of 0.1:1-1:1. The polyelectrolyte composition provides improved ionic conductivity and electrochemical properties, and can be used in batteries, e.g., a Li-ion battery.

摘要： An antimicrobial wipe is disclosed comprising a substrate and an antimicrobial composition. The antimicrobial composition contains a sulfonated block copolymer having an ion exchange capacity (IEC) of >0.5 meq/g, and (ii) a solvent system. The solvent system contains a mixture of two or more solvents selected from the group consisting of organic solvents, inorganic solvents, terpene-based compounds, and decarboxylated rosin acids. The antimicrobial wipe is in the form of a fabric, a sponge, a toilette, and the like. The sulfonated block copolymer is partially or fully dissolved in the solvent system, such that when the wipe is in contact with a target surface, the sulfonated block copolymer is imparted from the wipe onto the surface forming a coating layer. The coating layer causes a reduction in a microbe concentration by at least 1 log10 CFU (colony forming units) within 120 minutes upon contact.
