“…Recently, hybrid conductive organic polymers like polyaniline, poly (dioxy-3,4-ethylenethiophene) and polypyrrole were used with traditional additive manufacturing materials like metals, paving the transition from 3D to 4D printing. Compared with traditional 3D, 4D printed material structures could response to external stimuli (voltage, force, heat), which is the core properties of soft-robotics or flexible wearable electronics ( Martinelli et al, 2022 ).…”

Hybrid materials or hybrids incorporating organic and inorganic constituents are emerging as a very potent and promising class of materials due to the diverse but complementary nature of their properties. This complementarity leads to a perfect synergy of properties of the desired materials and products as well as to an extensive range of their application areas. Recently, we have overviewed and classified hybrid materials describing inorganics-in-organics in Part-I (Saveleva, et al., Front. Chem., 2019, 7, 179). Here, we extend that work in Part-II describing organics–on-inorganics, i.e., inorganic materials modified by organic moieties, their structure and functionalities. Inorganic constituents comprise of colloids/nanoparticles and flat surfaces/matrices comprise of metallic (noble metal, metal oxide, metal-organic framework, magnetic nanoparticles, alloy) and non-metallic (minerals, clays, carbons, and ceramics) materials; while organic additives can include molecules (polymers, fluorescence dyes, surfactants), biomolecules (proteins, carbohydtrates, antibodies and nucleic acids) and even higher-level organisms such as cells, bacteria, and microorganisms. Similarly to what was described in Part-I, we look at similar and dissimilar properties of organic-inorganic materials summarizing those bringing complementarity and composition. A broad range of applications of these hybrid materials is also presented whose development is spurred by engaging different scientific research communities.

“…[14] However, PEDOT:PSS is insoluble and infusible, thus, the synthesis of 3D conductive materials is still a challenge. [15,16] For that reason, additive manufacturing 3D printing methods are increasingly being used in order to create conductive hydrogels using different type of techniques such as inkjet printing, [17,18] extrusion-based printing [19][20][21] and light-based printing. [22][23][24] Very recently, we have shown that PEDOT can be copolymerized with poly(𝜖-caprolactone) (PCL) biopolyester, leading to PEDOT-g-PCL graft copolymers.…”

Functional inks for light‐based 3D printing are actively being searched for being able to exploit all the potentialities of additive manufacturing. Herein, a fast visible‐light photopolymerization process is showed of conductive PEDOT:PSS hydrogels. For this purpose, a new Type II photoinitiator system (PIS) based on riboflavin (Rf), triethanolamine (TEA), and poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is investigated for the visible light photopolymerization of acrylic monomers. PEDOT:PSS has a dual role by accelerating the photoinitiation process and providing conductivity to the obtained hydrogels. Using this PIS, full monomer conversion is achieved in less than 2 min using visible light. First, the PIS mechanism is studied, proposing that electron transfer between the triplet excited state of the dye (3Rf*) and the amine (TEA) is catalyzed by PEDOT:PSS. Second, a series of poly(2‐hydroxyethyl acrylate)/PEDOT:PSS hydrogels with different compositions are obtained by photopolymerization. The presence of PEDOT:PSS negatively influences the swelling properties of hydrogels, but significantly increases its mechanical modulus and electrical properties. The new PIS has also been tested for 3D printing in a commercially available Digital Light Processing (DLP) 3D printer (405 nm wavelength), obtaining high resolution and 500 µm hole size conductive scaffolds.

“…Polyaniline (PANI) is the most representative conductive polymer material, which has the advantages of structural stability, simple synthesis, low cost, and environmental friendliness. In recent years, it has shown good application prospects in biomedicine, 22 functional materials, 23,24 energy conversion and storage, 25–27 catalysis and other fields 28 . Over the years, a lot of research works using PANI as the carrier material of Ag NPs has been conducted 29–32 .…”

Ag nanoparticles (Ag NPs) nanocomposites are promising catalysts for nitro compound reduction, but simultaneously meeting the requirements of high catalytic activity, stability, recyclability and facile preparation is highly difficult. Herein, the three‐dimensional (3D) porous magnetic polyaniline (PANI) was synthesized using phytic acid (PA) as the dopant/crosslinker, and a recyclable PANI/Ag NPs nanocomposite (PMPA) was obtained through the in situ redox between PANI and AgNO3. Characterization results demonstrate that PMPA exhibits a typical 3D porous structure constructed by coral‐like PANI framework with well‐dispersed Ag NPs (10–20 nm) firmly anchored. The PMPA can efficiently catalyze the 4‐nitrophenol (4‐NP) reduction, with a reaction rate constant of 9.5 × 10−3 s−1 (and 1067.4 s−1 g−1), which is highly competitive to the previously reported high‐performance Ag NPs catalysts. This is probably due to the favorable mass/electron conduction of 3D porous structure and strong interaction between PA and Ag. Moreover, the magnetism renders PMPA recyclability via a simple magnetic attraction, and the reaction rate constant remains at a high level after six reuse cycles, up to 4.8 × 10−3 s−1. This work highlights the important role of 3D porous PANI in structure of Ag NPs nanocomposites, and paves a new way to develop recyclable catalysts with facile preparation and high catalytic performance.Highlights Facile synthesis via in situ reaction between 3D porous PANI and AgNO3. Stable dispersion and strong anchor attributed to phytic acid. Conductive porous structure to facilitate mass/electron transportation. Outstanding catalytic performance for 4‐NP reduction and recycle by magnetism.
