Abstract
Provided is a vinylidene fluoride resin film that is produced using a film composition including at least a vinylidene fluoride resin and inorganic particles; and that includes a plurality of protrusions on at least one surface thereof. Among the plurality of protrusions, the number of protrusions greater than 0.10 μm in height from a flat surface at which the protrusions are not present is from 7.0 to 50 per 0.10 mm2 of the vinylidene fluoride resin film.
Claims9
A vinylidene fluoride resin film comprising a film composition comprising a vinylidene fluoride resin and inorganic particles, wherein
- the vinylidene fluoride resin film comprises a plurality of protrusions on at least one surface thereof;
- among the plurality of protrusions, the number of protrusions greater than 0.10 μm in height from a flat surface at which the protrusions are not present is from 7.0 to 50 per 0.10 mm2 of the vinylidene fluoride resin film;
- the vinylidene fluoride resin is a vinylidene fluoride homopolymer;
- and
- a relationship 0.14<d/t<0.75 is satisfied, where an average particle size of the inorganic particles is d (μm) and a film thickness of the vinylidene fluoride resin film is t (μm).
