Folding Polymers with Pendant Hydrogen Bonding Motifs in Water: The Effect of Polymer Length and Concentration on the Shape and Size of Single-Chain Polymeric Nanoparticles

Stals, Patrick J. M.; Gillissen, Martijn A. J.; Paffen, Tim F. E.; de Greef, Tom F. A.; Lindner, Peter; Meijer, E. W.; Palmans, Anja R. A.; Voets, Ilja K.

A set of random copolymers based on a benzene-1,3,5-tricarboxamide functional methacrylate (BTAMA) and oligoethylene glycol methacrylate (oEGMA) with different degrees of polymerization (DP, from 110 to 450) and a 10 mol % loading of BTAMA were prepared using RAFT polymerizations. The pendant BTA units encode for the formation of helical…

Direct Observation of Plugs and Intrawall Pores in SBA-15 Using Low Voltage High Resolution Scanning Electron Microscopy and the Influence of Solvent Properties on Plug-Formation

Kjellman, Tomas; Asahina, Shunsuke; Schmitt, Julien; Impéror-Clerc, Marianne; Terasaki, Osamu; Alfredsson, Viveka

Through the use of low voltage high resolution scanning electron microscopy (LV-HRSEM) we have studied the fine details of the intricate pore structure of SBA-15. Intrawall pores and deviations from the ideal and uniform cylindrical pores are clearly observed, and we report for the first time the direct observation of…

Influence of microporosity in SBA-15 on the release properties of anticancer drug dasatinib

Kjellman, T.; Xia, X.; Alfredsson, V.; Garcia-Bennett, A. E.

The release of the hydrophobic cancer drug dasatinib from two mesoporous silica materials as drug delivery vehicles has been studied. One material is a reference 2D-hexagonal SBA-15 with the typical bimodal pore system with ordered primary mesopores and disordered intrawall pores. The other material is a modified version of the…

Orientation specific deposition of mesoporous particles

Kjellman, Tomas; Bodén, Niklas; Wennerström, Håkan; Edler, Karen J.; Alfredsson, Viveka

We present a protocol for a facile orientation specific deposition of plate-like mesoporous SBA-15 silica particles onto a surface (mesopores oriented normal to surface). A drop of an aqueous dispersion of particles is placed on the surface and water vaporizes under controlled relative humidity. Three requirements are essential for uniform…

Highly proton conducting electrolyte membranes based on poly (arylene sulfone) s with tetrasulfonated segments

Weiber, E. Annika; Takamuku, Shogo; Jannasch, Patric

A series of fully aromatic polymers having only sulfone bridges linking the aromatic rings have been synthesized via polycondensations and studied as proton-exchange membranes. Mixtures of tetrasulfonated 4,4′-bis-1,1′-biphenyl (BCPSBP), non-sulfonated BCPSBP, and 4,4′-thiobisbenzenethiol were copolymerized by nucleophilic aromatic substitution reactions to obtain…
