Polymer Shell Nanocapsules Containing a Natural Antimicrobial Oil for Footwear Applications
In this study, a series of melamine-formaldehyde (MF) nanocapsules containing essential oils as natural biocides with different polymer-to-oil ratio was prepared to be applied to footwear materials (lining, insoles, etc…) by an in situ polymerization (O/W) method. The nanocapsule physicochemical properties were characterized; the average size distribution was determined by DLS and the chemical structure was analyzed by FTIR spectroscopy. The antimicrobial effect of the essential oils was analyzed in solid media by measuring the inhibition diffusion halos in agar for 24 h. Finally, the incorporation of the synthesized nanocapsules into footwear materials was analyzed by scanning electron microscopy (SEM).
