“…Essential oils (EOs) are mixtures extracted from plants (i.e., flowers, buds, seeds, leaves, twigs, bark, herbs, wood, fruits, and roots), their main components present antimicrobial activity [1][2][3][4][5][6][7] and are used in medicine, agriculture, cosmetics, and food industry. [8] In particular the phenolic monoterpenes, as for instance thymol and carvacrol, isomers presenting the hydroxyl group (-OH) in different positions of the aromatic ring, [9] have been recognized as the principal active compounds extracted from thyme (Thymus vulgaris).…”

Thymol and carvacrol, relevant natural antimicrobial molecules, induce co‐crystallization and, in absence of any mechanical stretching, also high degrees of axial orientation on s‐PS amorphous fibers. The release of thymol and carvacrol from s‐PS co‐crystalline fibers has been analyzed to realize long‐term antimicrobial fabrics. Partition between isolated guest molecules, present in co‐crystalline phase or simply dissolved in the amorphous phase, has been investigated by FTIR and thermogravimetric measurements. These analyses have been confirmed by polarized FTIR spectra of axially oriented s‐PS films.
