Preparation and characterization of poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) films exhibiting the cocrystalline phase with carvacrol, a relevant natural antimicrobial, are reported. The relative intensity and linear dichroism of two O–H out-of-plane deformation peaks (at 698 and 717 cm−1) of carvacrol can be rationalized by assuming that these peaks are due to isolated and hydrogen-bonded guest molecules, respectively, and by slower desorption of carvacrol when included as isolated molecules in the cavities of the polymer host crystalline phase.
