Abstract: | In this work, PA-6 core and PMMA shell composite nanofiber mats together with pure PMMA and PA-6 nanofibrous membranes were
obtained through electrospinning. Two kinds of transparent composites were fabricated by hot pressing multilayers of the composite
nanofiber mats and of the interlaced pure PA-6 with PMMA nanofibrous membranes, respectively, under the same processing condition
and with the same amount of PA-6 nanofiber content. Tensile properties and visible light transmittances of the two transparent
composites were characterized. It has been found that both the tensile behavior and the visible light transmittance of the
composites obtained from the composite nanofiber mats were better than the counterparts from the interlaced pure PA-6 and
PMMA nanofibrous membranes. With a minor loss of less than 10 % in the transparency, a maximal increase of around 20 % in
the tensile modulus and tensile strength has been recognized for a transparent composite from the composite nanofibers. Although
less efficient, the tensile strengths of the composites from the interlaced nanofibrous membranes were all higher than that
of a transparent panel processed from the pure PMMA nanofibers. |
