Resumen:
Agustina Leonardi, María Eugenia Victoria Hormaiztegui,Veronica Lujan Mucci, Ignacio Esteban Dell´Erba, Maria Alejandra Fanovich andMirta Ines Aranguren, ?Functionalization of polyurethane nanocomposites witheither gold or silver nanoparticles?, SLAP 2018, Mar del Plata, 6-9 Noviembrede 2018.The aim of this work is the functionalization of films basedin polyurethanes and polycaprolactone (PU-PCL) with gold nanoparticles (AuNPs)or silver nanoparticles (AgNPs). The PU-PCL films can be prepared fromreactants obtained from renewable resources, giving a green alternative for thedevelopment of polymeric materials. They are used primarily as coatingmaterials or adhesives for various substrates. AuNPs with an average diameter close to 5 nm could be uniformlydispersed in the PU-PCL, these AuNPs showed a significant photothermal effecteven at very low concentrations when irradiated with a 532 nm laser at anirradiance close to 2 W/cm2. On the other hand, AgNPs synthesized employing glycerolas both solvent and reducing agent with a diameter close to 23 nm wereintroduced in the PU-PCL film. This kind of NPs has very interestingantibacterial properties. <!-- /* Font Definitions */ @font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face{font-family:Calibri;panose-1:2 15 5 2 2 2 4 3 2 4;mso-font-charset:0;mso-generic-font-family:swiss;mso-font-pitch:variable;mso-font-signature:-536859905 -1073732485 9 0 511 0;}@font-face{font-family:Times;panose-1:2 0 5 0 0 0 0 0 0 0;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:3 0 0 0 7 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-qformat:yes;mso-style-parent:"";margin:0cm;margin-bottom:.0001pt;mso-pagination:widow-orphan;font-size:12.0pt;font-family:Times;mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-bidi-font-family:"Times New Roman";mso-bidi-theme-font:minor-bidi;}.MsoChpDefault{mso-style-type:export-only;mso-default-props:yes;font-family:Times;mso-ascii-font-family:Times;mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-hansi-font-family:Times;mso-bidi-font-family:"Times New Roman";mso-bidi-theme-font:minor-bidi;}size:595.0pt 842.0pt;margin:72.0pt 72.0pt 72.0pt 72.0pt;mso-header-margin:35.45pt;mso-footer-margin:35.45pt;mso-paper-source:0;}div.WordSection1{page:WordSection1;}<!-- /* Font Definitions */ @font-face{font-family:Courier;panose-1:2 0 5 0 0 0 0 0 0 0;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:3 0 0 0 3 0;}@font-face{font-family:"Cambria Math";panose-1:2 4 5 3 5 4 6 3 2 4;mso-font-charset:0;mso-generic-font-family:roman;mso-font-pitch:variable;mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face{font-family:Calibri;panose-1:2 15 5 2 2 2 4 3 2 4;mso-font-charset:0;mso-generic-font-family:swiss;mso-font-pitch:variable;mso-font-signature:-536859905 -1073732485 9 0 511 0;}@font-face{font-family:Times;panose-1:2 0 5 0 0 0 0 0 0 0;mso-font-charset:0;mso-generic-font-family:auto;mso-font-pitch:variable;mso-font-signature:3 0 0 0 7 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal{mso-style-unhide:no;mso-style-qformat:yes;mso-style-parent:"";margin:0cm;margin-bottom:.0001pt;mso-pagination:widow-orphan;font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-font-family:"Times New Roman";}.MsoChpDefault{mso-style-type:export-only;mso-default-props:yes;font-size:10.0pt;mso-ansi-font-size:10.0pt;mso-bidi-font-size:10.0pt;font-family:Courier;mso-ascii-font-family:Courier;mso-fareast-font-family:Courier;mso-hansi-font-family:Courier;}size:612.0pt 792.0pt;margin:72.0pt 72.0pt 72.0pt 72.0pt;mso-header-margin:36.0pt;mso-footer-margin:36.0pt;mso-paper-source:0;}div.WordSection1{page:WordSection1;}mso-level-number-format:roman-lower;mso-level-tab-stop:324.0pt;mso-level-number-position:right;text-indent:-9.0pt;}ol{margin-bottom:0cm;}ul{margin-bottom:0cm;}
