Antimicrobial crosslinked polystyrene nanospheres with controlled release characteristics were produced via a mini-emulsion polymerization technique and characterized by SEM and dynamic light scattering. Depending on the composition and the amount of the surfactant added, this method produced distinct nanosized (35–200 nm) beads. Uniform films of selected nanobeads that incorporated polypropylene were subsequently uniaxially drawn. The release profile of the antimicrobial agent was correlated with the induced molecular orientation of the polymer matrix revealed by polarized Raman spectroscopy.
