Our aim is the development of copolymer and composite hydrogels that, when implanted under the human skin, swell osmotically and thereby induce skin growth. During the polimerization reaction we are produced copolymers with varyable composition, which are proceed from two acrylic compounds [N- isopropyl- acrylamide (NIPAAm), and acrylamide (AAm)]. The mechanical strength and the swelling stability of the gels are enhanced by the addition of fillers [Na- montmorillonite (Na- m.) and with alkyl- ammonium ion organophilized Na- montmorillonites [(C n - m.), n = 4, 12, 18]. With this method we are synthetized composite- hydrogels. The filler content of composites varies between 1 and 25 wt%. We observed that in the case of composites synthesized with the addition of fillers, relatively low filler contents (1-5 wt%) resulted in more extensive swelling and stronger gel structure. In the course of the experiments the monomer composition of the gels (0/100-100/0 mol% NIPAAm/AAm) and in the case of composites, the quality (montmorillonite and organophilized montmorillonite) and quantity (1-25 wt%) of fillers are varied. The extent of swelling and the viscoelastic properties can be manipulated through the ratios of these parameters. In the case of certain copolymer and composite gels, values of desorption enthalpy (ΔH m ) corresponding to the actual water contents were also determined by thermoanalytical measurements (DSC). Swelling values determined by gravimetry and enthalpies calculated from DSC measurements were found to be in good correlation. Evaluation and comparison of the rheological and DSC results also allowed conclusions to be drawn concerning the types of interaction operating among the three components of the system, i.e. the polymer skeleton, the filler and water molecules. We found that water molecules within the gel matrix are bound to the 3-D polymer lattice with bonds of different strengths and the strength of these interactions are dependent on both hydrophilicity and charge conditions. In the case of hydrophobic NIPAAm composites a more extensive swelling can be achieved by applying montmorillonite fillers with hydrophobized surfaces, whereas in the case of hydrophilic AAm-based composites the use of hydrophilic montmorillonite fillers ensure more extensive swelling.}, keywords = {COPOLYMERS; DSC; mechanical properties; Skin expander; Swelling hydrogel; clay- mineral composites}, year = {2009}, eissn = {1788-0718}, pages = {13-32}, orcid-numbers = {Janovák, László/0000-0002-2066-319X; Kemény, Lajos/0000-0002-2119-9501; Dékány, Imre/0000-0001-5472-5355} } @mastersthesis{MTMT:246963, title = {Határfelületi és kolloid kölcsönhatások montmorillonit, vas-oxid, huminsav és kalciumion tartalmú összetett vizes diszperz rendszerekben}, url = {https://m2.mtmt.hu/api/publication/246963}, author = {Majzik, Andrea}, publisher = {SZTE}, unique-id = {246963}, year = {2008} } @article{MTMT:1329873, title = {Evolution of Surface Functional Groups in a Series of Progressively Oxidized Graphite Oxides}, url = {https://m2.mtmt.hu/api/publication/1329873}, author = {Szabó, Tamás and Berkesi, Ottó and Forgó, Péter and Vargáné Josepovits, Katalin and Sanakis, Yiannis and Petridis, Dimitris and Dékány, Imre}, doi = {10.1021/cm060258+}, journal-iso = {CHEM MATER}, journal = {CHEMISTRY OF MATERIALS}, volume = {18}, unique-id = {1329873}, issn = {0897-4756}, keywords = {MODEL; REDUCTION; composite; Nanotubes; C-13}, year = {2006}, eissn = {1520-5002}, pages = {2740-2749}, orcid-numbers = {Szabó, Tamás/0000-0001-8182-640X; Berkesi, Ottó/0000-0001-6184-1768; Forgó, Péter/0000-0002-0279-6896; Dékány, Imre/0000-0001-5472-5355} } @article{MTMT:1026051, title = {Hydration behavior and dynamics of water molecules in graphite oxide}, url = {https://m2.mtmt.hu/api/publication/1026051}, author = {Lerf, A and Buchsteiner, A and Pieper, J and Schottl, S and Dékány, Imre and Szabó, Tamás and Boehm, H P}, doi = {10.1016/j.jpcs.2006.01.031}, journal-iso = {J PHYS CHEM SOLIDS}, journal = {JOURNAL OF PHYSICS AND CHEMISTRY OF SOLIDS}, volume = {67}, unique-id = {1026051}, issn = {0022-3697}, year = {2006}, eissn = {1879-2553}, pages = {1106-1110}, orcid-numbers = {Dékány, Imre/0000-0001-5472-5355; Szabó, Tamás/0000-0001-8182-640X} } @article{MTMT:1013230, title = {Preparation of ultrathin membranes by layer-by-layer (LBL) deposition of oppositely charged inorganic colloids}, url = {https://m2.mtmt.hu/api/publication/1013230}, author = {Varga, Viktória and Erdőhelyi, András and Dékány, Imre}, doi = {10.1007/s00396-005-1405-3}, journal-iso = {COLLOID POLYM SCI}, journal = {COLLOID AND POLYMER SCIENCE}, volume = {284}, unique-id = {1013230}, issn = {0303-402X}, year = {2006}, eissn = {1435-1536}, pages = {611-619}, orcid-numbers = {Varga, Viktória/0000-0001-9933-7604; Erdőhelyi, András/0000-0002-0889-3988; Dékány, Imre/0000-0001-5472-5355} } @article{MTMT:1013229, title = {Preparation and investigation of structural and photocatalytic properties of phosphate modified titanium dioxide}, url = {https://m2.mtmt.hu/api/publication/1013229}, author = {Kőrösi, László Tamás and Dékány, Imre}, doi = {10.1016/j.colsurfa.2006.01.052}, journal-iso = {COLLOID SURFACE A}, journal = {COLLOIDS AND SURFACES A : PHYSICOCHEMICAL AND ENGINEERING ASPECTS}, volume = {280}, unique-id = {1013229}, issn = {0927-7757}, year = {2006}, eissn = {1873-4359}, pages = {146-154}, orcid-numbers = {Dékány, Imre/0000-0001-5472-5355} } @article{MTMT:1011029, title = {Enhanced acidity and pH-dependent surface charge characterization of successively oxidized graphite oxides}, url = {https://m2.mtmt.hu/api/publication/1011029}, author = {Szabó, Tamás and Csákiné Tombácz, Etelka and Nyergesné Illés, Erzsébet and Dékány, Imre}, doi = {10.1016/j.carbon.2005.08.005}, journal-iso = {CARBON}, journal = {CARBON}, volume = {44}, unique-id = {1011029}, issn = {0008-6223}, year = {2006}, eissn = {1873-3891}, pages = {537-545}, orcid-numbers = {Szabó, Tamás/0000-0001-8182-640X; Csákiné Tombácz, Etelka/0000-0002-2068-0459; Nyergesné Illés, Erzsébet/0000-0002-2901-9616; Dékány, Imre/0000-0001-5472-5355} } @article{MTMT:247013, title = {Photooxidation of dichloroacetic acid controlled by pH-stat technique using TiO2/layer silicate nanocomposites}, url = {https://m2.mtmt.hu/api/publication/247013}, author = {Kun, Róbert and Szekeres, Márta and Dékány, Imre}, doi = {10.1016/j.apcatb.2006.07.012}, journal-iso = {APPL CATAL B-ENVIRON}, journal = {APPLIED CATALYSIS B-ENVIRONMENTAL}, volume = {68}, unique-id = {247013}, issn = {0926-3373}, year = {2006}, eissn = {1873-3883}, pages = {49-58}, orcid-numbers = {Dékány, Imre/0000-0001-5472-5355} }
