synthesis of acrylic core shell Composite Polymers and properties of plastisol gels
Progress in Organic Coatings, 2004Co-Authors: G J Wang, C.-s. Kang, R G JinAbstract:Abstract Heterogeneous latices of acrylic core–shell Polymers were designed and prepared via a two-stage seeded emulsion polymerization for plastisol–gel of automotive underbody coatings and body sealers. 1,6-Hexanediol diacrylate (HDDA) was introduced to the rubbery core and/or the glassy shell with interpenetrating polymer network (IPN). The latices were characterized by submicron particle sizer, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The properties of plastisol–gels prepared by mixing the core–shell Polymers and DOP/TCP plasticizers were investigated by testing the storage stability of plastisols and the mechanical properties of plastigels. These novel core–shell Polymers represent a highly positive innovation and a wide application in automotive industry instead of the hazardous material PVC plastisol.

urethane acrylic Composite polymer emulsions
Progress in Organic Coatings, 1996Co-Authors: Yoshihiro Okamoto, Yoshiki Hasegawa, Fumio YoshinoAbstract:Blends of waterborne urethane and acrylic polymer systems were studied to obtain a Composite emulsion that would have all of the advantages of the two Polymers without their associated disadvantages. An approach to achieve extensive polymer-polymer interactions through crosslinking reactions was studied to optimize the positive aspects of each polymer. The crosslink system used an acrylic polymer emulsion containing keto or aldo groups and a polyurethane dispersion incorporating a hydrazine group. The degree of crosslinking was determined by FT-IR Single package, ambient temperature crosslinking emulsions were obtained by using this system. In addition to the excellent properties these two Polymers normally possess, the crosslinked blends exhibit synergistic effects in film properties, such as good solvent resistance and low heat sensitivity over a wide range. Composite Polymers of this type could be useful in applications where high durability is required: tennis court coatings, floor coatings, laminating adhesives. and paper and textile finishes.

Magnetic filaments for anisotropic Composite Polymers
Nanotechnology, 2020Co-Authors: Laurence Ourry, Damien Le Roy, Samir Mekkaoui, Thierry Douillard, Anne-laure Deman, Vincent SallesAbstract:The use of contactless magnetic forces meets numerous needs in microelectromechanical systems (MEMS) or microfluidic devices. In this view, heterogeneous materials integrating magnetic nanostructures within a non-magnetic matrix such as polymer can produce local variations of magnetic field, at the sub-micrometer scale. Here we report on the synthesis of magnetic Composites using electrospun nanofilaments and a polydimethylsiloxane (PDMS) matrix. Varying the precursor nature and heat treatment conditions, we obtained single phase filaments of Fe, FeNi, and MFe2O4 (M = Co, Fe, Ni). Thanks to a fine investigation of their structure and morphology, it was possible to measure from magnetically-soft (µ0HC ≤ 5 mT) to relatively hard (µ0HC up to 93 mT, MR/MS up to 0.5) behaviors. The common one-dimensional shape of these filaments leads to an anisotropic magnetic response. This can be exploited to achieve self-organization of the filaments in arrays within the non-magnetic matrix. We show the first step towards the development of magnetically anisotropic membranes of PDMS with 0.23 wt% Fe filaments. These Composite materials are promising for implementing magnetic functions in microsystems while circumventing complex micro-fabrication steps.

conductive films based on Composite Polymers containing ionic liquids absorbed on crosslinked polymeric ionic like liquids sillps
Polymer, 2015Co-Authors: Belen Altava, Vicente Compan, Andreu Andrio, L F Del Castillo, Sergio Molla, M I Burguete, Eduardo Garciaverdugo, Santiago V LuisAbstract:Polymerization of styrenic monomers containing imidazolium subunits in the presence of crosslinking monomers and using ionic liquids (ILs) as porogenic agents provides Composite materials with excellent mechanical properties and displaying conductivities that are in the same order of magnitude than those shown by bulk ILs. This approach allows the use of high crosslinking degrees and low IL-loadings without compromising the required properties of the resulting Composites. Besides, no appreciable leaching of the bulk IL component is detected.
