Several experimental techniques were used to evaluate cork and membrane surface modification after plasma treatment and the influence on the microcapsules adsorption, namely, Static and Dynamic Contact Angle, Energy Dispersive Spectroscopy (EDS), Fourier Transform Infrared Spectroscopy (FT-IR), Differential Scanning Calorimetry (DSC), Scanning Electron Microscopy (SEM) and Tensile Strength. The plasma treatment greatly increases the hydrophilicity of both materials, justifying that more microcapsules are adsorbed on this composite. Chemical and physical characterization of the cork agglomerate and polymer membrane confirmed significant surface alteration.

Different experimental techniques were used to evaluate the surface alterations of the substrate pretreated with DBD plasma, namely, static and dynamic contact angle, surface energy, energy dispersive spectroscopy (EDS), scanning electronic microscopy and differential scanning calorimetry. Plasma discharge greatly increases the wettability and surface energy of the samples. Chemical and physical analyses of the cork agglomerate confirmed considerable surface modification.

Por ser tratar de um material inerte, muitas vezes torna-se necessário modificar a superfície deste substrato com o intuito de melhorar a sua interação com outros tipos de materiais nos processos de estamparia, tingimento, acabamentos entre outros. Diferentes técnicas foram utilizadas para analisar a cortiça após o tratamento plasmático. Verificou-se, com os resultados obtidos, que o plasma DBD foi capaz de melhorar as propriedades superficiais de um aglomerado de cortiça e sua interação com microcápsulas, criando a possibilidade de desenvolver produtos sustentáveis e inovadores.
