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. 2015 (Kemény Lajos (Bőrgyógyászat, immunoló...); 2015.05.07. 10:25:14) false true true false true false GOLD 2025-05-13 true https://doi.org/10.1556/Nano.2008.00002 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 false false false false 2015-09-13T20:57:04.000+0000 2015-05-07T10:34:08.000+0000 Bőrgyógyászati és Allergológiai Klinika (SZTE / SZAOK); Kolloidkémiai Tanszék (SZTE / TTIK / KTCS) 4 25 2 4 0 false 10080109 10067876 Language 10002 /api/language/10002 Angol Angol English true 2 true PersonAuthorship 4237861 /api/authorship/4237861 Janovák, L ✉ [Janovák, László (Kémia), szerző] Kolloidkémiai Tanszék (SZTE / TTIK / KTCS) 1 0.25 true false true Author 10030258 /api/author/10030258 Janovák László (Kémia) Janovák László true 10030258 true Janovák L true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false 17985733 true PersonAuthorship 6288117 /api/authorship/6288117 Varga, J [Varga, János (plasztikai sebészet), szerző] Bőrgyógyászati és Allergológiai Klinika (SZTE / SZAOK) 2 0.25 false false Author 10028324 /api/author/10028324 Varga János (plasztikai sebészet) Varga János true 10028324 true Varga J true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false 21583669 true PersonAuthorship 6288118 /api/authorship/6288118 Kemény, L [Kemény, Lajos (Bőrgyógyászat, im...), szerző] Bőrgyógyászati és Allergológiai Klinika (SZTE / SZAOK) 3 0.25 false false Author 10001275 /api/author/10001275 Kemény Lajos (Bőrgyógyászat, immunológia) Kemény Lajos true 10001275 true Kemény L true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false 21583668 true PersonAuthorship 6288119 /api/authorship/6288119 Dékány, I [Dékány, Imre (Kolloidkémia, any...), szerző] 4 0.25 false true Author 2034702 /api/author/2034702 Dékány Imre (Kolloidkémia, anyagtudomány) Dékány Imre true 2034702 true Dékány I true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false 21583667 true PublicationIdentifier 978944 /api/publicationidentifier/978944 DOI: 10.1556/Nano.2008.00002 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true GOLD true IDENTICAL 10.1556/Nano.2008.00002 https://doi.org/10.1556/Nano.2008.00002 false 1135861 true PublicationIdentifier 978943 /api/publicationidentifier/978943 Scopus: 77954824604 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true false DIFFERENT 77954824604 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-77954824604 false 1135860 true PublicationIdentifier 15919992 /api/publicationidentifier/15919992 Matarka: 982204 PlainSource 33 /api/publicationsource/33 Matarka PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Matarka Matarka https://matarka.hu/egy-kozlemeny-oldala.php?MatarkaID=@@@ true true 33 true IDENTICAL 982204 https://matarka.hu/egy-kozlemeny-oldala.php?MatarkaID=982204 false true Classification 10154 /api/classification/10154 Fizika true true Classification 10293 /api/classification/10293 Kémiai tudományok true true Classification 12215 /api/classification/12215 Klinikai orvostan true true Classification 10002 /api/classification/10002 Természettudományok true true Keyword 3582 /api/keyword/3582 COPOLYMERS true 3582 true Keyword 4359 /api/keyword/4359 DSC true 4359 true Keyword 11684 /api/keyword/11684 mechanical properties true 11684 true Keyword 1113991 /api/keyword/1113991 Skin expander true 1113991 true Keyword 1113993 /api/keyword/1113993 Swelling hydrogel true 1113993 true Keyword 1353200 /api/keyword/1353200 clay- mineral composites true 1353200 true Reference 1990366 /api/reference/1990366 1.
