Determinación de la energía libre superficial del líquido sinovial humano en biomateriales
2021
In this work, the results of adherence between human synovial fluid and two specific implant materials, polytetrafluoroethylene (PTFE) and Cobalt-Chromium-Molybdenum (Co-Cr-Mo), are investigated through the measurement of contact angles. Behavior, which is a function of the interactions between liquid and solid surface, is analyzed; Surfaces determine the shear stress relation, coefficient of friction, and flow. The interaction between synovial fluid and prosthetic construction materials is poorly understood. The method used was the sessile drop, and evaluated with Young’s equation.
