| Sumario: | The development of sustainable and multifunctional gel coats for fiber reinforced polymer (FRP) composites is crucial for expanding their range of applications. To address these issues, this study developed FRP composite, by introducing an ionic liquid (IL) in the gel coat as a finish coating. The novelty of this work relies in the activation of the gel coat by IL as a functional filler, in order to introduce static dissipative and antibacterial characteristics, two relevant functional characteristics of advanced coatings. The coating is based on the IL 1-butyl-3-methylimidazolium dicyanamide [BMIM][DCA] with an environmentally friendly epoxy resin, ensuring a reduced environmental impact, compared with traditional coatings in FRP composites. The influence of the incorporation of the IL in the gel coat on the morphological, structural, mechanical, antibacterial, and electrical properties were evaluated. The addition of IL increased the tensile strength, tensile strain, and flexural strain at break by 14%, 30%, and 20%, respectively compared to uncoated laminates. Meanwhile, coating decreased the flexural stress at break by around 6%. Notably, the presence of the IL demonstrated antimicrobial activity against E. coli, and S. aureus efficiently. Moreover, it demonstrated static dissipative characteristics after the IL addition. This study demonstrates a more sustainable way of adjusting the surface characteristics of FRP laminates |
