Structure and Properties of Nano-Scale Regenerated Silk Nonwoven
Electrospinning was used to fabricate nano-scale regenerated silk nonwoven (ERSF). The distribution of pore diameter in the nonwoven was measured with a mercury porosimeter. The effects of area density (g/m2) of ERSF on air and water permeability, water absorption and mechanical properties were investigated. Meanwhile, the orient characteristics of mechanical properties were discussed. The results showed that the average pore diameter of ERSF was about micra, and the specific surface area was high when the mercuric capacity was bulky. With the increase of the area density, the air penetrability and the contact angle with water of ERSF tended to decrease, while the water transmission rate had no evident change. The breaking strain, stress and specific breaking energy of ERSF were especially prominent affected by the area density. It could be concluded that nano-scale regenerated silk nonwoven was isotropy in mechanical properties, because the direction of a sample had no notable impact on the stress-strain behavior.
