High-performance membranes for protein separation are of great interest. In this study, new type of polysulfone (PSf) composite ultrafiltration membranes are created by blending PSf with polyaniline (PANi) nanofibers and functionalized multi-walled carbon nanotubes (MWNTs) and then casting the mixture solutions via a well-developed non-solvent/solvent induced phase separation technique, using deionized water as the coagulation bath. The compositions, morphologies and properties of as-formed membranes are fully investigated. We demonstrate that membrane characteristics such as porosity, hydrophilicity, conductivity and thermal stability for PSf can be significantly enhanced with the incorporation of hydrophilic and conductive compositions of functionalized-MWNTs and PANi nanofibers. The composite membranes exhibit comparable bovine serum albumin (BSA) selectivities (89-93 vs. 92%) but much improved water fluxes (31.5-88.9 vs. 9.2 gfd/psi) against pure PSf membranes.

AbstractSoft electronic devices that are bendable and stretchable require stretchable electric or electronic components. Nanostructured conducting materials or soft conducting polymers are one of the most promising fillers to achieve high performance and durability. Here, we report silver nanoparticles (AgNPs) embedded with single-walled carbon nanotubes (SWCNTs) synthesized in aqueous solutions at room temperature, using NaBH4 as a reducing agent in the presence of highly oxidized SWCNTs as efficient nucleation agents. Elastic composite films composed of the AgNPs-embedded SWCNTs, Ag flake, and polydimethylsiloxane are irradiated with radiation from a Xenon flash lamp within a time interval of one second for efficient sintering of conductive fillers. Under high irradiation energy, the stretchable electrodes are created with a maximum conductivity of 4,907 S cm−1 and a highly stretchable stability of over 10,000 cycles under a 20% strain. Moreover, under a low irradiation energy, strain sensors with a gauge factor of 76 under a 20% strain and 5.4 under a 5% strain are fabricated. For practical demonstration, the fabricated stretchable electrode and strain sensor are attached to a human finger for detecting the motions of the finger.
