Synthesis of Emulsion-Templated Acrylic-Based Porous Polymers: From Brittle to Elastomeric

Tunc, Yeliz
Hasırcı, Nesrin
High internal phase emulsion polymers (PolyHIPEs) are novel materials that have high porosity and interconnected open-cell structure and are used in various applications such as supports for catalytic systems, media for separation of similar molecules, and scaffolds for tissue engineering. In this study, 90% porous acrylic based polyHIPE structures with various cellular structure and mechanical characteristics were developed by using stearyl acrylate (SA), isodecyl acrylate (IDA), isobornyl methacrylate (IBMA), and divinylbenzene (DVB). Elastomeric polyHIPEs were produced from the comonomers of SA and IDA, and had high ability of recovery when the applied stress was removed. IBMA based polyHIPEs were brittle and demonstrated higher Young's modulus and compression strength than that of conventional styrene based polyHIPEs at the same void volume. Therefore, by varying the composition, it became possible to alter the mechanical properties of polyHIPEs from brittle to elastomeric, without changing the interconnected cellular structures.


Synthesis of acrylic based high internal phase emulsion polymers and their application in chromatography
Tunç, Yeliz; Hasırcı, Nesrin; Department of Polymer Science and Technology (2009)
High internal phase emulsion polymers (PolyHIPEs) are new generation materials with their high porosity and interconnected open-cell structures and finds applications in areas such as supports for catalytic systems, separation media and tissue engineering scaffolds. Styrene based PolyHIPEs are currently the most popular choice, but solvent compatibility and poor mechanical properties of these materials prevent their applications. Therefore development of new polyHIPEs with desired mechanical and cellular pr...

Koltuksuz, Barış; Tinçer, İsmail Teoman; Özçubukçu, Salih; Department of Polymer Science and Technology (2015)
High density polyethylene (HDPE) and polypropylene (PP) are two commonly used thermoplastic polymers existing in the commodity plastic market due to their developed and easy post-reactor processability characteristics. Although these two polymers can be subjected to reprocessing, they eventually experience critical losses in their main physical and mechanical properties at elevated temperatures. With the aim of preventing these losses in their mechanical and thermal properties in their individual and blende...

A series of novel photocrosslinked shape-stabilized phase change materials (PCMs) based on tetradecanol and lauric acid have been prepared by UV technique for the purpose of thermal energy storage applications. Both lauric acid and tetradecanol were reacted with glycidyl methacrylate to form acrylated structures for covalently integrate into polyurethane (PU) based UV matrix to prevent leakage problem. The heating process phase change enthalpy is measured between 9 and 77 J/g, and the freezing process phase...

It is demonstrated that aqueous dispersions of micrometer-sized liquid crystal (LC) droplets provide the basis of a general and facile methodology for the templated synthesis of spherical and nonspherical polymeric micro-particles with complex internal structure and porosity. Specifically, nematic droplets of reactive (RM257)/nonreactive mesogens with distinct internal configurations are prepared using a range of approaches, the reactive mesogens are photopolymerized, and then the nonreactive mesogens are e...
Synthesis of CuO nanostructures on zeolite-Y and investigation of their CO2 adsorption properties
Boruban, Cansu; Nalbant Esentürk, Emren (2017-10-01)
Copper(II) oxide (CuO) nanoparticles (NPs) in two different morphologies, spiky and spherical, were synthesized on zeolite-Y by a modified impregnation method, and their CO2 adsorbing capabilities were investigated under standard conditions (1 atm and 298 K). The properties and CO2 adsorption performances of the hybrid systems were characterized by transmission electron microscopy, scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, X-ray photoelectron spectroscopy, atomic absorption s...
