Abstract

In this article, we present new samples of lamellar magnetic nanocomposites based on the self-assembly of a polystyrene-b-poly(n-butyl methacrylate) diblock copolymer synthesized by atom transfer radical polymerization. The polymer films were loaded with magnetic iron oxide nanoparticles covered with polystyrene chains grown by surface initiated-ATRP. The nanostructuration of the pure and magnetically loaded copolymer films on silicon was studied by atomic force microscopy, ellipsometry, neutron reflectivity and contact angle measurement. The present study highlights the strong influence of the copolymer extremity - driven itself by the choice of the ATRP chemical route - on the order of the repetition sequences of the blocks in the multi-lamellar films. In addition, a narrower distribution of the nanoparticles' sizes was examined as a control parameter of the SI-ATRP reaction.

Production of singlet oxygen (1O2), a selective reactive oxygen species (ROS) produced by irradiation under visible light of organic photosensitizers, has attracted increasing interest in the fields of fine chemistry,1photo-decontamination of air/water,2antimicrobial materials,3or Photodynamic Therapy (PDT).4Immobilization of photosensitizers on solid substrates improves their handling, recyclability, stability and facilitates purification steps to remove photocatalyst from reactants in fine chemistry. In that context, functional waterborne latex synthesized by the scalable emulsion polymerization process, are versatile to prepare photosensitizer-supported materials either as stable colloidal particles or as polymer film. We will present two strategies to design photosensitizer-grafted polymer colloids. First, film forming latex particle with a decorated shell will be synthesized by polymerization-induced self-assembly (PISA, Fig. 1 left).5Secondly, crosslinked particles will be synthesized by miniemulsion copolymerization to produce core-functionalized particles(PISA, Fig. 1 right). The organic photosensitizer chosen to synthesize the functional monomer is the Rose Bengal molecule.

Abstract

The four-step synthesis of amphiphilic glycopolymers associating dextran as backbone and poly(methyl methacrylate) (PMMA) as grafts is reported, using the “grafting from” strategy. In the first step, the dextran OH functions were partially acetylated. The second step consisted in linking initiator groups by reaction of 2-bromoisobutyryl bromide (BiBB) with the unprotected OH functions. Third, the atom transfer radical polymerization (ATRP) of methyl methacrylate was carried out in DMSO from the resulting dextran derivative used as a macroinitiator. Finally, the cleavage of the acetate groups led to the expected glycopolymers. Careful attention was given both to the copolymer structure and the control of polymerization. PMMA grafts were analyzed by SEC-MALLS after their deliberate cleavage from the backbone to evidence a controlled polymerization. Moreover, the mildness of the final deprotection conditions was proved to ensure acetate cleavage without either degrading dextran backbone and PMMA grafts or cleaving grafts from dextran backbone. © 2008 Wiley Periodicals, Inc.
