| Abstract Scope |
The consumption of coconut water generates a large amount of fiber. These natural fibers for being exposed to the environment can suffer different types of degradation. One type of degradation is the photochemistry caused by ultraviolet (UV) radiation from solar radiation, which can cause scission in the molecular chains of the fibers and morphological changes. This work aimed to evaluate the changes caused on the surface of coconut fiber when exposed to ultraviolet (UV) radiation for 50 hours, being evaluated through the analysis of water absorption index, scanning electron microscopy (SEM), and roughness. Based on the results presented, it is concluded that UV radiation causes chemical and superficial changes in coconut fibers, making them more hydrophobic and rough. |
