“…Recently, corresponding examples have newly appeared in the literature for the engineering of various ME-MOPs. [43][44][45][46][47][48] From the aspect of synthesis, the combined noncovalent and covalent assembly strategies for the engineering of ME-MOPs can be classied into three cases: selftemplate noncovalent-covalent synthesis, concomitant noncovalent and covalent synthesis, and step-by-step noncovalent and covalent synthesis.…”

“…Some methods for preparing POP films have been reported previously, such as surface-initiated growing, layerby-layer crosslinking, hyper-branched structuring, etc. 116,[160][161][162] However, it is quite difficult to control the structure of materials in these methods, and the prepared films are often nonporous. To meet the practical requirements, it is highly desirable to develop a method to prepare thin films which can retain both polymeric framework and porosity.…”

Foam Silica Films Synthesized by Calcium Chloride-Assisted Emulsification

The development of porous films presenting accessible high specific surface area is important to design new adsorbents, sensors or catalyst supports. Here, we describe a simple method to prepare a foam silica coating by using an evaporation induced emulsification method assisted by calcium chloride. An alcoholic silica sol containing calcium chloride and a poly(ethylene oxide) containing polymer is deposited on a substrate by dip-coating. The alcohol evaporation induces a phase separation between a silica-rich phase and a calciumrich one. The droplets size increases via a coalescence process until the sol gelation, which determines the final pore size comprised between 100 nm and 3 µm. Thermal analysis and droplet evaporation monitoring both confirm that the solvent departure is delayed by the presence of calcium chloride into the sol. Influence of the polymer nature on the porosity is discussed. Using a block copolymer such as the Pluronic F-127, which strongly stabilizes the emulsion, allows to reach a low pore size (400 nm) while on the opposite, we propose to use a short poly(ethylene glycol) (PEG) such as the PEG-400, which weakly stabilizes it, leading 2 to larger pores (2-3 microns). Moreover, we show that adding a zirconium salt (ZrOCl 2 .8H 2 O) into the silica sol speeds up the condensation step of the silica network and leads to the decreasing in the pore size.
