“…It supports the proposed mechanism of continuous flux of hydrophobic PPy particles formed during rapid mixing of Py solution with FeCl 3 solution followed by agglomeration at the air‐water interface. The X‐Ray Diffraction pattern of the PPy film is shown in Figure (c) which indicates the amorphous nature of the film with a similar kind of pattern as reported for powder PPy . The characteristic broad scattering peak of PPy is observed at 2θ=25.2 ° , corresponding to a d‐spacing of 3.5 A ° .…”

“…[16] However,t he processability remains ac hallenging issue because the water/oil interfaces formed in the bulk liquid phases can be easily disturbed by external interference,w hich hamper the continuous fabrication of PPy films. [17] This issue could be effectively settled by our superspreading strategy.Since the fluidity of the confined oil layer was restricted by the organogels,the stability of the spreading liquid layer was significantly improved. Theoxidant and monomer were introduced to the water phase and oil layers,r espectively (Figure 4b).…”

Liquid spreading is of significant interest in science and technology. Although surface topography engineering and liquid surface-tension regulating can facilitate spreading, the spreading layers in these strategies are inevitably inhomogeneous or contaminated with surfactants. Herein, we show a general strategy to realize the superspreading of liquids on mutually soluble gel surfaces. The cooperation of the hydraulic pressure under liquid phase and liquid-like property of gel surfaces can dramatically eliminate the local pinning effect and enhance the advancement of three-phase contact line, thus forming stable and homogeneous superspreading liquid layers. Such liquid layers can be converted into various functional thin polymer films with controlled thicknesses (nm- to µm-scale) through one-step polymerization of the reactants. Our strategy offers opportunities for large-scale synthesis of versatile functional thin films for various applications.

Recently,m etal-organic frameworks (MOFs) with multifunctional pore chemistry have been intensively investigated for positioning the desired morphology at specific locations onto substrates for manufacturing devices.H erein, we develop am icro-confined interfacial synthesis (MIS) approach for fabrication of av ariety of free-standing MOF superstructures with desired shapes.T his approach for engineering MOFs provides three key features:1 )insitu synthesis of various free-standing MOF superstructures with controlled compositions,s hape,a nd thickness using am old membrane; 2) adding magnetic functionality into MOF superstructures by loading with Fe 3 O 4 nanoparticles;3 )transferring the synthesized MOF superstructural arrayontoflat or curved surface of various substrates.The MIS route with versatile potential opens the door for an umber of new perspectives in various applications.Metal-organic frameworks (MOFs) are ac lass of multifunctional porous materials which are composed of metal ions and organic ligands linked through coordination bonds,a nd possessing open framework structures with inherent high microporosities.[1] With their facile preparation, high porosity, and tunable architecture,great efforts have been devoted, in the last two decades,t ot he synthesis of new open architectures with distinctive properties. [1, 2] Recently,i ntensive research efforts are focused on controlling the morphology for construction of zero-(0D), one-(1D), two-(2D), and three-dimensional (3D) superstructures composed of wellintergrown nanocrystals as building blocks on desired substrates for device applications,s uch as sensors,e lectronics, supercapacitors,and batteries. [3][4][5][6][7] Forf ull and broad utilization of MOFs,i ti sh ighly desirable to have the capability to fabricate af ree-standing MOF superstructure formable in any desired shape and to transfer this shaped superstructure to any desired substrate. Theb ottom-up approaches reported, such as LangmuirBlodgett deposition, layer-by-layer,l iquid-phase epitaxy,o r self-assembly monolayer method are often complex, time consuming,a nd the shaping of the MOF involves multistep procedures.[4] Usually as econdary growth reaction was necessary on the seed-deposited surface of the substrate. Thus,the extra steps of template removal or peeling from the substrate might be needed to collect the free-standing MOF structures with specific shape,w hich often damaged the MOFs,leading to defects.Moreover,i mparting functionality and heterogeneity to MOFs has not yet been fully exploited, with the use of inappropriate additives,such as binders for fragile crystalline MOFs that damage their pristine features. [7] Therefore,i ti s desirable to develop an innovative synthetic method to localize such coordination reactions within ad esired space for structuring the free-standing MOF assemblies into films, membranes,o rp atterns.I np articular,t he transfer of the structured MOF features would facilitate the integration of MOFs into device fabrication for application sys...
