Abstract

processo de obtenção de biomateriais poliméricos via laser infravermelho 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.
