description The present invention describes a method for producing biomaterials by using an infra-red laser to cause two polymer materials to adhere to each other. These biomaterials have numerous uses, in particular as polymer supports, scaffolds and coatings for artificial joint prostheses. The method improves the mechanical properties of the polymers, achieving satisfactory adhesion between the hydrogel and the substrate, minimising the wear of the components that form orthopedic devices, for example, which is one of the main causes of failure of such devices. La présente invention décrit un procédé d'obtention de biomatériaux par adhésion entre deux matériaux polymères au moyen d'un laser infrarouge. Parmi les nombreuses applications convenant à ces biomatériaux, on distingue les supports, les échafaudages et les revêtements polymères pour utilisation dans des prothèses articulaires artificielles. Le procédé améliore les propriétés mécaniques des polymères, permettant d'obtenir une adhésion appropriée entre l'hydrogel et le substrat, d'où une réduction de l'usure subie par les composants constituant les dispositifs orthopédiques, par exemple, l'une des principales causes de défaillance de ces dispositifs. A presente invenção descreve um processo de obtenção de biomateriais pela adesão entre dois materiais poliméricos, empregando laser infravermelho. Uma das inúmeras aplicações que cabem a esses biomateriais destacam-se suportes, scaffolds e recobrimentos poliméricos para uso em próteses articulares artificiais. O processo melhora as propriedades mecânicas dos polímeros, obtendo uma adesão adequada entre o hidrogel e o substrato, minimizando o desgaste sofrido pelos componentes que constituem dispositivos ortopédicos, por exemplo, um dos principais fatores que geram sua falência.
