PROCESS FOR PRODUCING POROUS FILMS AND FILM MATERIAL PRODUCED THEREFROM

A process for producing porous films (2), with the film (2) having a polymer matrix (M) and discrete domains (D) being provided in the matrix (M). According to the invention, it is proposed that the film (2) be subjected to a field for selective excitation of the domains (D), that the domains (D) be...

Zusammenfassung:A process for producing porous films (2), with the film (2) having a polymer matrix (M) and discrete domains (D) being provided in the matrix (M). According to the invention, it is proposed that the film (2) be subjected to a field for selective excitation of the domains (D), that the domains (D) be heated selectively relative to the remainer of the matrix by the excitation and that the pores (12) be produced in the domains (D) or in the region of the domains (D).
