“…Recently, our research group proposed a new efficient approach to producing PHMs carrying inorganic NPs on the surface of pores 31, 32. The strategy utilized two effects occurring concurrently: PIPS in the mixture containing a monomer, an initiator, a crosslinker, a porogen solvent and NPs, and the diffusion of NPs to the interface between the polymer and the porogenic solvent.…”

Polymer-based porous hybrid materials (PHMs) carrying inorganic nanoparticles on the surface of pores have important applications in chemical and biological sensing, in chromatography, and in heterogeneous catalysis. This Feature Article provides an overview of the recent developments in the synthesis and fabrication of multifunctional PHMs using polymerizationinduced phase separation. Exemplary applications of a PHM coated with gold nanorods were demonstrated for the simultaneous detection of different analytes using surface enhanced Raman scattering (SERS) spectroscopy and fl uorescence microscopy.

We investigated by Transmission Electron Microscopy (TEM) the morphologies of crosslinked copolymers from methacrylate monomers from methylmethacrylate (MMA) and trifluoroethylmethacrylate (TFEMA), polydimethylsiloxane (PDMS) macromers with molecular weight (Mn) of 1,700 and 4,700 g/mol, and crosslinker. Depending on the PDMS content, we observed, spherical PMMA islands in which small PDMS domains were dispersed, PMMA continuous phase, closely packed PTFEMA islands, and homogeneously dispersed PDMS domains were observed with low or middle magnification. Fine observation at 100,000‐fold magnification revealed the “fundamental” common size domain, which was determined by the Mn value of the PDMS macromer. Thus we found two microstructure types: (1) a “fundamental domain” due to the Mn of the PDMS macromer, and (2) an aggregated domain. The former was constant under all conditions, but the latter was affected by the comonomer and its ratio. The present results are essential in understanding the chemical and physical characteristics of crosslinked copolymers from PDMS macromers. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Additive manufacturing is a technology that promises to disrupt the conventional manufacturing industry due to its ability to create complex structures with improved macroscopic control not available with existing techniques like molding or milling. In addition to superior macroscopic structural control, photoprinting methods such as digital light projection can enable molecular‐scale control over the fabrication process by taking advantage of the self‐sorting or assembly properties of the monomers themselves. Polymerization‐induced phase separation (PIPS) allows for the remarkable introduction of microscopic control into additive manufacturing, using polymer‐rich and polymer‐poor regions that rely on incompatibilities to phase separate during polymerization creating new complex materials not achieved by traditional methods. With the incorporation of porogens or filler materials, microporosity and/or surface functionalization can be introduced in a facile one‐step printing process. This expands the potential applications of 3D printed materials, to include micro‐ and macroscale structural control. Using PIPS as a design strategy, polymeric materials with previously unprecedented capabilities can be produced with ease enabling 3D printing to grow into its full potential as a manufacturing tool. © 2024 Society of Chemical Industry.
