Aligned mat with coaxially spun PVP-5CB fibers a) before, b) during and c) after toluene exposure. Images on the left were taken when the mat was observed under nonchromatic crossed polarizers (scale bar 10 mm). In the right column, the images were captured during POM observation of the mat using crossed polarizers (scale bar 80 μm).
