“…PNIPAM features a near body lower critical solution temperature (LCST = 32°C) and biocompatibility, and is thus very appealing for biomedical applications. [32][33][34][35][36] So far the reports mentioning both PVDF and PNIPAM only describe polymer blends for the preparation of electrospun fibers or flat membranes, or the grafting of PNIPAM on PVDF membranes. 37 To date, the preparation of PNIPAM-b-PVDF block copolymers (BCPs) and the study of their self-assembly in selective solvents have not been reported.…”

“…Furthermore, the internal resistance of modified-SWNT films, arising from the physical contact between components and the electron transfer resistance between the active materials and the substrate, could reflect the adhesion and π-π stacking system between copolymers and the nanotube [32][33][34]. Therefore, electrochemical impedance spectroscopy (EIS) measurements were performed from 10 5 Hz to 0.01 Hz.…”

One silsesquioxane-polythiophene hybrid copolymer, with combined star-like structure and intramolecular heterogeneity, was synthesized and sufficiently characterized via various methods, including FTIR, NMR, and SEC measurements. According to the exploration and characterization results, it was much more efficient at modifying SWNTs than its linear analogs in aqueous solution. The hydrophobic silsesquioxane core and PEDOT chains could locally anchor to the surface of the nanotubes, while the soluble flexible copolymer chains extended into the solution and rigid conjugated chains provided some π-π stacking effect to enhance adhesive force with the conjugated structure of the carbon nanotube, imparting steric stabilization to nanotube dispersion. The noncovalent interaction with SWNTs and solubility in aqueous solution improved the electrochemical characteristics of the modified-SWNT composite and availed for the preparation of a flexible and transparent electroactive film. Accordingly, this kind of silsesquioxane-polythiophene hybrid copolymer will be forwarded to apply to the assembling of flexible optoelectronic devices.

“…In recent years, biomolecular computing, as a significant branch of unconventional operations, has been responsible for numerous scientific developments and breakthroughs [1][2][3][4]. Of these, logic computing devices constructed by the integration of biocatalytic reaction and stimuli-responsive film electrode have shown enormous potential in some fields, such as biosensing [5][6][7], information transmission [8,9], medical diagnostics [10,11], and drug delivery [12]. However, these logic devices reported were often simple in operation and unable to simulate complex environments.…”

N-isopropylacrylamide was polymerized on the surface of copper-plated carbon paper electrode by a novel redox initiation system composed of persulfate and copper nanoparticles, and the PNIPAAmÀ Cu NPs@CP film electrode was obtained. Cyclic voltammetry (CV) results showed that the electrode exhibits a reversible temperature, pH and glucose switchable electrical signal response through the ferrocene carboxylic acid (Fc-(COOH)). With this basis, a 4-current output logic gate system consisting of 3-response inputs of temperature, pH, and glucose was fabricated and a corresponding logic circuit for 3-input/4-output ports was established. This work might provide a new avenue for the development of multi-valued biologic systems.
