“…This feature would be advantageous for mass production in industrial‐scale preparations and commercial applications. An exceptional method for LbL assembly, that is 2‐in‐1 assembly, without sequential step‐by‐step film assembly of polyanion and polycation, was proposed by Schaaf and co‐workers . Alternate films with various combinations including poly(3,4‐ethylenedioxythiophene) with poly(styrene sulfonate), branched poly(ethyleneimine) with poly(styrene sulfonate), poly(diallyldimethylammonium) with poly(styrene sulfonate), and poly(allylamine hydrochloride) with poly(styrene sulfonate) were prepared by spin‐coating or dipping‐and‐drying from a single solution containing polycation/polyanion complexes.…”

mechanisms operate with excellent fl exibility/adaptability originating from cooperation of multiple dynamic systems. [ 1 ] In most cases, the functional components of these systems are assembled through non-covalent dynamic interactions. Although their assembled structures are often ambiguous, or "fuzzy," functions of biological systems are signifi cantly superior to any of the so far precisely constructed artifi cial machines and devices. Thus, fabrication of bio-like systems might be one of the ultimate goals of the science and technology of functional materials. There has already been some success in the synthesis of excellent new materials, [ 2 ] but these are still far inferior to biological materials systems from the point-of-view of specifi city, effi ciency, and adaptability, although incremental progress involving existing technological concepts may not change this situation. A certain paradigm shift in construction concepts of functional materials is necessary to establish an advanced approach towards truly dynamic functions.Fabrication of functional materials requires control of organization of their components with nanometer precision. The novel technological concept of nanotechnology has been established over the past few decades with a view to exploit nanometer-sized phenomena and to fabricate functional materials by precisely controlling the materials' structures at the nanoscale. [ 3 ] Several strategies of nanotechnology are simple extensions of the corresponding successful microtechnologies to nanofabrication. However, the control of nanoscale events and structures requires different approaches to those commonly applied in microtechnology. This is because physical phenomena at the nanoscale are quite different from microscopic phenomena. Effects occurring at the microscopic level are often similar to those occurring in the macroscopic regime. In contrast, nanoscale phenomena involving nanometer-sized objects are strongly infl uenced by thermal/statistical fl uctuations, mutual interactions, and possibly quantum effects between components. In many cases, such mutual actions are dynamically integrated, often resulting in unexpected properties and effects so that components of nanoscale systems cannot be controlled by intuitive means. To understand and therefore control nanoscale phenomena and to Objects in all dimensions are subject to translational dynamism and dynamic mutual interactions, and the ability to exert control over these events is one of the keys to the synthesis of functional materials. For the development of materials with truly dynamic functionalities, a paradigm shift from "nanotechnology" to "nanoarchitectonics" is proposed, with the aim of design and preparation of functional materials through dynamic harmonization of atomic-/molecular-level manipulation and control, chemical nanofabrication, self-organization, and fi eld-controlled organization. Here, various examples of dynamic functional materials are presented from the atom/molecularlevel to macroscopic dimensions. Thes...

“…[44,45] While the deposition of charged species remains the preferred approach, by favoring hydrogen bonding or unconventional bonding between the materials, several studies also report the adsorption of non-charged materials via inorganic-organic hybrid assemblies, stereocomplexed materials or lithographic techniques, thus, expanding the range to other materials than polyelectrolytes. [46][47][48] The aforementioned LbL-assemblies allow for the incorporation of pharmaceutical agents within the coating film to obtain control over the kinetics of the release of the incorporated agent using pH-driven changes. [49][50][51] The different synthesis routes for polyelectrolyte polymers include ionic polymerization, group transfer polymerization, controlled radical polymerization (Atom Transfer Radical Polymerization (ATRP), Reversible Addition Fragmentation chain Transfer (RAFT)), emulsion polymerization and group transfer polymerization.…”

Electrospun nanofibrous membranes offer superior properties over other polymeric membranes not only due to their high membrane porosity but also due to their high surface-to-volume ratio. A plethora of available polymers and post-modification methods allow the incorporation of "smart" responsiveness in fiber membranes. The pHresponsive property is achieved using polymers from the class of polyelectrolytes, which contain pH-dependent functional groups on their polymeric backbone. Electrospinning macroscopic membranes using polyelectrolytes earned considerable interest for biomedical and environmental applications due to the possibility to trigger chemical and physical changes of the membrane (swelling, wettability, degradation) in response to environmental pH-changes. Here, we review recent advancements in the field of electrospinning of pHresponsive nanofiber materials. Starting with the chemical background of pH-responsive polymers at the molecular level, we highlight the material-property transformation upon pH-change at the macroscopic membrane level and, finally, we provide an overview of recent applications of pH-responsive fiber membranes.

“…Taking in consideration that PEI and PEDOT:PSS are a polycation and a negatively charged zwitterion, respectively, a layer-by-layer method was employed for their deposition [32]. Firstly, a PEI anchoring layer was formed by immersing electrodes into a 1.5 mg/mL PEI solution for 20 min.…”

“…Drop-casting, spin-coating and inkjet printing seem to be the best alternatives. However, many publications report that films of the same conducting polymer obtained using distinct deposition methods show different characteristics [31,32]. These factors affect the reproducibility of standard potentials and the potential stability, important characteristics of ISE for their mass production.…”

Simple, robust, sensitive and low-cost all-solid-state ion-selective electrodes (SCISEs) are of interest in different fields, such as medicine, veterinary, water treatment, food control, environmental and pollution monitoring, security, etc.as a replacement for traditional ion-selective electrodes with liquid inner contact. In spite of their potential advantages, SCISEs remain mainly in the research laboratories. With the motivation of developing simple and low-cost SCISEs with possible commercial applications, we report a comparison study of six different commercial conducting materials, namely, polypyrrole-block-polycaprolactone (PPy-b-PCaprol), graphene/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) ink, poly(3,4-ethylenedioxythiophene):polyethylenglycol (PEDOT:PEG), high conductivity PEDOT:PSS, polyethylenimine (PEI) with PEDOT:PSS for their possible use as ion-to-electron transducer in polyurethane based pH-SCISEs. Among all studied pH-SCISES, PEDOT:PEG based electrodes exhibited the best results in terms of sensitivity, reproducibility and lifetime. Finally, these sensors were tested in different real samples showing good accuracy.
