The upper and lower surface of son point layer 20, includes quantum dot 21 and diffusion particle 22 inside quantum dot layer.
The quantum dot film of water oxygen obstructing capacity high that the present invention is provided proposed first, and quantum dot is scattered in into crystallinity or half
Crystalline linear resin is central and is made film, because the linear resin of crystallinity or hemicrystalline has (1) strand Cheng Zhi
Chain, it is easy to close-packed arrays；(2) molecule chain rigidity is not high, does not have huge side base, and steric hindrance is small, and strand is be easily moved
The characteristics of.After linear resin film forming after the part as quantum dot layer, now linear resin molecule is still within amorphous state,
Quantum dot layer is heated to more than the glass transition temperature of resin, below melt temperature, the now volumetric expansion of linear resin,
Strand has enough kinergety and the free space to carry out the adjustment of Molecular connectivity indices, and strand is uniform in quantum dot layer
The nucleator of distribution is that lattice-site generation initial orientation is arranged in crystallite, and this phenomenon is that heterogeneous nucleation is crystallized.Wherein, meeting is crystallized
The transparency of quantum dot film is being influenceed to a certain degree, and the nucleator of addition can not only improve the crystalline rate of linear resin, also
The size of spherocrystal in resin can be reduced so that linear resin remains to keep the high grade of transparency after crystallizing, and does not interfere with liquid
Light in brilliant backlight module makes the optical effect of quantum dot film be guaranteed by quantum dot film.
Meanwhile, in the preparation technology of quantum dot film, direction that simple tension makes the strand of resin is carried out to film again
Orderly structure is arranged in, this phenomenon contributes to the homogeneous nucleation of resin to crystallize.
Under the collective effect of above two principle, the crystalline rate of linear resin molecule is greatly improved.Resin crystallization with
Afterwards, because strand makees regular tightly packed, the free volume of resin reduces, density increase, and then makes quantum dot layer entirety
Density increases, and vapor and oxygen molecule are difficult to pass through, even if the end face of quantum dot film is not covered with water oxygen barrier layer and can also prevent
Sealing steam and oxygen molecule enter the inside of quantum dot film, so as to play the protective effect to quantum dot.
The quantum dot film of the water oxygen obstructing capacity high that the present invention is provided avoids high temperature preparation method of the prior art, prevents
Destruction of the water oxygen to quantum dot in preparation process is stopped, there is the quantum dot film of the water oxygen obstructing capacity high being prepared into water oxygen to hinder
