FILLER DISPOSITION FILM
A filler disposition film that can use a commercially procurable filler material having good particle diameter uniformity, enables high positional precision of the filler disposition, can support even an increase in the surface area, and has a prescribed filler regularly disposed in a long resin film. Moreover, the rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more the average particle diameter of the prescribed filler, and a width of 0.2 mm or greater is 90% or greater. Such a rectangular area has a long-side direction that is substantially parallel to the long-side direction of the filler disposition film, and a widthwise direction that is substantially parallel to a short-side direction of the filler disposition film. The average particle diameter of the regularly disposed filler is from 0.4 μm to 100 μm.
1 . A filler disposition film in which a prescribed filler is regularly disposed in a long resin film, wherein
a rate of consistency of disposition of the filler in the filler disposition film in rectangular areas of a prescribed size having a length of 1000 times or more an average particle diameter of the filler, and a width of 0.2 mm or greater is 90% or greater.
2 . The filler disposition film according to claim 1 , wherein the rate of consistency of disposition of the filler is 98% or greater.
3 . The filler disposition film according to claim 1 , wherein the rectangular area is repeatedly present in a long-side direction of the filler disposition film.
4 . The filler disposition film according to claim 1 , wherein the rectangular area is any rectangular area in the filler disposition film.
5 . The filler disposition film according to claim 1 , wherein
a long-side direction of the rectangular area is substantially parallel to a long-side direction of the filler disposition film, and
a widthwise direction of the rectangular area is substantially parallel to a short-side direction of the filler disposition film.
6 . The filler disposition film according to claim 1 , wherein the average particle diameter of the regularly disposed filler is 400 nm or greater.
7 . The filler disposition film according to claim 1 , wherein the average particle diameter of the regularly disposed filler is 100 μm or less.
8 . The filler disposition film according to claim 1 , wherein a length in the long-side direction of any rectangular area is 50000 times or less the average particle diameter of the filler.
9 . The filler disposition film according to claim 1 , wherein a width in the short-side direction of any rectangular area is 500 mm or less.
10 . The filler disposition film according to claim 1 , wherein a film length of the filler disposition film is from 5 m to 5000 m.
11 . The filler disposition film according to claim 1 , wherein a number density of the regularly disposed filler is from 100 fillers/cm 2 to 50000000 fillers/cm 2 .
12 . The filler disposition film according to claim 1 , wherein the regularly disposed filler has substantially a same shape.
13 . The filler disposition film according to claim 1 , wherein the regularly disposed filler is disposed flush in the film surface direction of the filler disposition film.
14 . The filler disposition film according to claim 1 , further comprising another type of filler other than the regularly disposed filler.
15 . The filler disposition film according to claim 1 , wherein a surface of the resin film in the vicinity of the filler is concave or has waviness with respect to a tangent plane of the resin film at a central portion between adjacent fillers.
16 . A filler disposition film according to claim 1 wherein the filler disposition film is wound onto a winding core to form a film wound body.
17 . A method for controlling the filler disposition film according to claim 1 , the method including: marking in advance before and after an area in which an omission is present with respect to an original disposition of the filler, a non-disposition area, or an area of a different disposition, or recording these areas.
