Sep 15, 2020 · Cross-linked nanofiber films had a water contact angle change rate of 24.2%-40% in 10 s, which was much lower than that of uncross-linked nanofiber (50.8%). This may be because the polar groups on the zein/PVA molecular chain were consumed during the cross-linking reaction, which reduced the hydrophilicity of the nanofibers.

Our results show that the microhardness and elastic modulus for cross-linked chitosan films are higher than the uncross-linked films.

The TGA curves of uncross-linked blends, analyzed under nitrogen atmosphere, are shown in Fig. 3.The temperatures of 5 and 10% decomposition for both uncross-linked and cross-linked blends are summarized in Table 2.These temperatures decrease with increasing wax content for uncross-linked blends, being somewhere … In contrast to chemical cross-links, physical cross-links are formed by weaker interactions. For example, sodium alginate gels upon exposure to calcium ions, which form ionic bonds that bridge between alginate chains. [5] Both uncross-linked and cross-linked composite films have an amorphous structure with homogenous aspect and different degrees of flexibility depending on the alginate/k-carrageenan ratio. It is worth mentioning that the fully cross-linked composite films are water resistant, an indispensable characteristic that defines a hydrogel formation.
