As already referred, antimicrobial polymers can be prepared either by embedding an antimicrobial
agent into the polymer bulk during their processing or by applying a surface coating or modification
as a chemical or physical finishing treatment. Over the past decade, several surface grafting techniques
have been studied; however, the method used strongly depends on if the textile fiber is natural or
synthetic and also on its physico-chemical features. Different techniques have been used to achieve
textiles surface grafting, such as: (1) chemical grafting; (2) plasma-induced grafting using either
radiofrequency or microwave plasma; (3) radiation-induced grafting, which uses high-energy radiation
(e.g., -Co60 rays); and (4) light-induced grafting using a source of ultraviolet radiation [24,52,89].
