The first metal layer 14 is cascading the surface with the first hard conating 12, therefore both surface configurations and the first hard conating 12
Surface configuration is identical.Therefore, in the first metal layer 14 and 14 corresponding region of particle, multiple raised 16 can be formed.
Similarly, when containing particle 15 in the second hard conating 22, the surface of second metal layer 24 can also form multiple raised 16.
When using volume to volume technique (roll to roll process) to manufacture the transparent conductive film 10 of strip, by
The surface of the first metal layer 14 and/or second metal layer 24 is set to form multiple raised 16 in particle 15.Therefore, transparent lead is being crimped
During electric thin film 10, multiple raised 16 can make to form point contact between two neighboring metal level, so as to prevent its inter-adhesive, pressure
Connect.
The bottom surface for being additionally, since particle 15 is planar structure.Therefore, the contact between particle 15 and base material 11 is changed into face and connect
Touch, contact area increase.When transparent conducting film 10 crimps, the pressure that particle 15 applies to the surface of base material 11 is fixed
, but because contact area increases, therefore particle 15 is smaller to pressure caused by base material 11, so as to be effectively prevented to base material 11

When transparent conducting film 10 crimps, and projection 16 forms support between two adjacent metal levels, can effectively prevent because of soil
The surface of body 16 has raised structures and the surface of metal level is caused to damage.
Specifically in the present embodiment, particle 15 is hemispherical and/or semi-cylindrical.In the first hard conating 12 and the second hard painting
In layer 22, the shape of particle 15 can be that one kind can also be a variety of mixing of different shapes.Wherein, hemispherical and semi-cylindrical
Particle be easy to machine-shaping, so as to advantageously reduce cost.
It is appreciated that in other embodiments, the shape of particle 15 is not limited to as both the above type.For example, particle
15 can also be in truncated cone-shaped, taper etc..
Further, in the present embodiment, line of the center of gravity of particle 15 positioned at the center along bottom surface 151 to top surface 153
On, and center of gravity is located at line close to one end of bottom surface 151.
That is, center of gravity is closer to bottom surface 151.First hard conating 12 and the second hard conating 22 (being collectively referred to as hard conating below)
Forming process it is as described above.When preparing transparent conducting film 10, elder generation's cloth by way of coating on the surface of base material 11
If the adhesive resin of a layer fluid shape；Before treating adhesive resin solidification, prefabricated particle 15 is sprayed thereon；Particle 15 exists
Natural subsidence in the presence of gravity, until being contacted with the surface of base material 11；Finally, solidify adhesive resin, can be included
The hard conating of particle 15.
Because the center of gravity of particle 15 is closer to bottom surface 151.Similar to the principle of tumbler, particle 15 in infall process just
Can occur autonomous upset under gravity, and cause bottom surface 151 towards base material 11 surface (certainly, based on probability, and
Not all particle 15 can be overturn to bottom surface 151 towards base material 11.But in all particles 15, bottom surface 151 is towards base material 11
Account for the overwhelming majority).Therefore, without taking other operations, the setting of the direction of particle 15 can be realized, so as to effectively simplify
The preparation flow of transparent conducting film 10.
In order to realize that more preferably resist blocking and that and resistance to compression connect effect, for the first metal layer 14 and the table of second metal layer 24

The height of projection 16, refer to that projection 16 protrudes from the height on the first metal layer 14 and/or the surface of second metal layer 24
Degree.Because the size of particle 15 is smaller, therefore it is difficult to be accurately controlled each raised 16 height.Therefore, by projection 16
Highly control is in above-mentioned altitude range.It is pointed out that in actual production, due to being difficult to each particle 15
Accurately controlled, therefore the height for having the projection 16 that few partial particulate 15 is formed being difficult to avoid that is located above range
Outside.But influenceed caused by part projection 16 negligible.
In general, the height of projection 16 is higher, then resist blocking and that effect is better.But with the rise of height,
The size of grain 15 so as to cause the haze value of transparent conducting film 10 also to increase therewith, and reaches one mutually in requisition for increase
Determine will to have a strong impact on after degree the optical effect of transparent conducting film 10.And in above-mentioned altitude range, transparent conductivity
Film 10 can preferably take into account resist blocking and that and optical effect.
Wherein, the height of projection 16 can be changed by adjusting the suspension degree of the size of particle 15 and particle 15.
