Resumo: | The use of inorganic nanoparticles in polymer nanocomposites allows gain in mechanical resistance and new properties. However, the incorporation of organic layer functionalized nanoparticles alters the material’s properties in a not fully understood manner. This work has the objective of analyzing the nature of interaction between the organic layer functionalized nanoparticles and the commercial polyurethane adhesive matrix (Adcote 555) and the consequences over physical-chemical properties in relation to the mass percentage of nanoparticles added. The nanoparticles were synthesized with a magnetite core and a poly(1,4-butanediol) organic shell. The mixtures were divided in two groups: low nanoparticles concentration, from 0,05%wt to 5,0%wt, and highly concentrated, up to 90%wt. Tensile and DSC tests allowed the nanocomposites mechanical and thermal properties analysis, respectively. MET imaging and SAXS analysis allowed to determine inorganic core and organic shell sizes, respectively. The nanocomposites’ mechanical behavior wasn’t the expected for conventional nanocomposites. On the contrary, the organic shell seems to have a camouflage effect over the inorganic core and the mechanical and thermal behavior seem the be guided more strongly by the volumetric fraction of the nanoparticles organic shell than their inorganic cores. Thus, it was concluded that the nanocomposites’ properties are ruled by the interphase between matrix and organic shell. The magnetite core’s contribution was to attribute magnetic properties to the highly concentrated nanocomposites. |

Contudo, a adição de nanopartículas funcionalizadas com capa orgânica altera as propriedades do material de forma ainda não plenamente estudada. Este trabalho tem como objetivo analisar a natureza da interação entre nanopartículas funcionalizadas com capa orgânica e a matriz polimérica de adesivo comercial de base poliuretano (Adcote 555) e as consequências sobre as propriedades físico-químicas do adesivo em função do percentual mássico de nanopartículas incorporadas. As nanopartículas foram sintetizadas com núcleo de magnetita e capa orgânica de poli(1,4-butanodiol). A incorporação de nanopartículas foi realizada em dois grupos de concentração: concentrações baixas, de 0,05% até 5,0% em massa, e em altas concentrações, até 90% em massa. Ensaio de tração uniaxial e de DSC permitiram análise do comportamento mecânico e térmico, respectivamente, das composições. Análise de MET e de SAXS permitiram verificação do tamanho dos núcleos e da capa orgânica das nanopartículas, respectivamente. As composições não se comportaram mecanicamente da forma esperada para nanocompósitos convencionais. Ao contrário, a capa orgânica parece ter efeito de camuflagem do núcleo inorgânico e o comportamento mecânico e térmico foi mais fortemente guiado pela contribuição volumétrica da capa orgânica das nanopartículas do que de seus núcleos inorgânicos. Assim, concluiu-se que as propriedades do nanocompósito são regidas pela interfase entre matriz e capa orgânica. A contribuição do núcleo de magnetita foi atribuição de características magnéticas aos nanocompósitos altamente concentrados.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)CNPq: 131365/2016-9CAPES: 001FAPESP: 2016/13191-7porUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMUFSCarNanocompósitos poliméricosNanopartículas inorgânicas funcionalizadas com capa orgânicaPolymer nanocompositesInorganic nanoparticleENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICA::MATERIAIS NAO METALICOSNanocompósitos de poliuretano comercial e nanopartículas híbridas de núcleo Fe3O4 funcionalizado com capa orgânica de Poli(1,4-Butanodiol)Nanocomposites of commercial polyurethane and hybrid nanoparticles of Fe3O4 nucleus and Poly(1,4-butanediol) organic shellinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisOnline6006009c25e6a7-a2cd-4058-97ed-441bc2793123info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINAL_VD Dissertação Cibele.pdf_VD Dissertação Cibele.pdfVersão Definitiva Dissertação de Mestradoapplication/pdf1639750https://repositorio.ufscar.br/bitstream/ufscar/10646/1/_VD%20Disserta%c3%a7%c3%a3o%20Cibele.pdfeb841c0f181fda256c7e365dc8f91b4aMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81957https://repositorio.ufscar.br/bitstream/ufscar/10646/3/license.txtae0398b6f8b235e40ad82cba6c50031dMD53TEXT_VD Dissertação Cibele.pdf.txt_VD Dissertação Cibele.pdf.txtExtracted texttext/plain94741https://repositorio.ufscar.br/bitstream/ufscar/10646/4/_VD%20Disserta%c3%a7%c3%a3o%20Cibele.pdf.txtdaf8f9334d492b671ea108d01bb19cc3MD54THUMBNAIL_VD Dissertação Cibele.pdf.jpg_VD Dissertação Cibele.pdf.jpgIM Thumbnailimage/jpeg6364https://repositorio.ufscar.br/bitstream/ufscar/10646/5/_VD%20Disserta%c3%a7%c3%a3o%20Cibele.pdf.jpg4b0d2c14c32455ca010b3790be60f6e9MD55ufscar/106462023-09-18 18:31:17.688oai:repositorio.ufscar.br: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Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:17Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |

The use of inorganic nanoparticles in polymer nanocomposites allows gain in mechanical resistance and new properties. However, the incorporation of organic layer functionalized nanoparticles alters the material’s properties in a not fully understood manner. This work has the objective of analyzing the nature of interaction between the organic layer functionalized nanoparticles and the commercial polyurethane adhesive matrix (Adcote 555) and the consequences over physical-chemical properties in relation to the mass percentage of nanoparticles added. The nanoparticles were synthesized with a magnetite core and a poly(1,4-butanediol) organic shell. The mixtures were divided in two groups: low nanoparticles concentration, from 0,05%wt to 5,0%wt, and highly concentrated, up to 90%wt. Tensile and DSC tests allowed the nanocomposites mechanical and thermal properties analysis, respectively. MET imaging and SAXS analysis allowed to determine inorganic core and organic shell sizes, respectively. The nanocomposites’ mechanical behavior wasn’t the expected for conventional nanocomposites. On the contrary, the organic shell seems to have a camouflage effect over the inorganic core and the mechanical and thermal behavior seem the be guided more strongly by the volumetric fraction of the nanoparticles organic shell than their inorganic cores. Thus, it was concluded that the nanocomposites’ properties are ruled by the interphase between matrix and organic shell. The magnetite core’s contribution was to attribute magnetic properties to the highly concentrated nanocomposites. |
