摘要

A novel Nylon-6 fishnet fiber with the anti-adhesion of seaweeds was prepared by UV radiation-initiated grafting of acrylic acid (AA) onto Nylon-6 fibers, and its structure was characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The influences of grafting conditions, such as irradiation dose, temperature, concentration of monomer, inorganic acid, and inhibitor etc., on grafting rate were studied, and the antiadhesion of seaweeds was evaluated with Dunaliella. The results showed that the grafting amount of Nylon-g-AA was increased with the increase of irradiation time. With the increase of concentration of AA, temperature, reaction time, inorganic acid, and inhibitor, the grafting amount increased firstly and then decreased, respectively. Nylon-6 fibers modified by Poly(acrylic acid) (PAA) had a strong effect on the adhesion of Dunaliella, and the antiadhesion was improved with the increase of the grafting amount. Results from the mechanical analysis revealed that the tensile strength of the UV-irradiation fibers decreased.
