Description
본 발명은 침상형 무기입자 분산액, 필름용 조성물, 확산 필름 및 광학 부재에 관한 것이다.The present invention relates to a dispersion of acicular inorganic particles, a composition for a film, a diffusion film, and an optical member.
광학적으로 투명한 고분자 재료는 낮은 비용과 양호한 가공성, 가시광 영역에서의 높은 투과율 때문에 광학적 코팅과 광전자 소재로 널리 사용되고 있다. 최근에는 고굴절의 투명한 소재가 광학 필터, 렌즈, 반사면(reflector), 광도파로(optical waveguide), 확산필름(diffusion film), 반사 방지 필름(antireflection films), 태양전지(solar cell) 및 발광 다이오드(light emitting diode, LED)의 소재로 사용되고 있다. Optically transparent polymer materials are widely used as optical coatings and optoelectronic materials because of their low cost, good processability, and high transmittance in the visible light region. Recently, high refractive transparent materials have been used in optical filters, lenses, reflectors, optical waveguides, diffusion films, antireflection films, solar cells and light emitting diodes ( It is used as a material for light emitting diode (LED).
특히, 확산필름은 조명에 적용되는 경우 눈부심을 방지하기 위해 필수적인 것으로, 통상 투명한 플라스틱 재질로 된 기재 상에 광확산 비드를 코팅하거나 점착하여 제조된다. 또는, 확산필름의 일면 또는 양면에 마이크로 렌즈나 렌티큘러와 같은 광학 패턴을 형성하기도 한다. 그러나 확산필름은 그 형태상 광확산 효과가 제한적일 수 있고 유연하기도 하므로, 경우에 따라서는 더 두꺼우며 상대적으로 강성이어서 구조체의 역할도 겸할 수 있는 확산판으로 대체되거나 확산필름과 확산판이 함께 적용되는 경우도 있다.In particular, the diffusion film is essential to prevent glare when applied to lighting, and is usually manufactured by coating or adhering light diffusion beads on a substrate made of a transparent plastic material. Alternatively, optical patterns such as micro lenses or lenticulars may be formed on one or both sides of the diffusion film. However, since the diffuser film may have a limited light diffusion effect due to its shape and is flexible, in some cases it is thicker and relatively rigid, so it is replaced by a diffuser plate that can also serve as a structure, or when a diffuser film and a diffuser plate are applied together There is also
그러나, 확산필름은 어떤 형태이든 빛을 확산시키는 과정에서 불가피하게 광손실이 발생한다는 문제가 있다. 확산효과를 증대시키기 위해 확산판을 사용하는 경우에는 이 문제가 더 부각되는 경향이 있다.However, there is a problem that light loss inevitably occurs in the process of diffusing light in any form of the diffusion film. This problem tends to be more prominent when a diffusion plate is used to increase the diffusion effect.
확산필름의 일면에 광확산 입자로 이루어진 입자층을 형성하는 경우, 광확산용 입자로서 등방성 입자와 이방성 입자로 구분될 수 있다. 그러나, 입사 광량은 일정하기 때문에 필요한 방향으로만 광을 확산함으로써 휘도를 향상시키는 입자에 대한 연구가 필요한 실정이다.When a particle layer made of light diffusing particles is formed on one surface of the diffusion film, particles for light diffusing may be classified into isotropic particles and anisotropic particles. However, since the amount of incident light is constant, it is necessary to study particles that improve luminance by diffusing light only in a necessary direction.
본 발명은 상술한 문제점을 해결하기 위한 것으로, 본 발명의 목적은, 확산 투과성을 개선시킬 수 있는 침상형 무기입자 분산액, 필름용 조성물, 확산 필름 및 광학 부재를 제공하는 것이다.The present invention is to solve the above problems, and an object of the present invention is to provide an acicular inorganic particle dispersion, a composition for a film, a diffusion film, and an optical member capable of improving diffusion permeability.

본원에서 사용된 용어 "침상"은 가느다란, 침상 결정의 방사형 덩어리로 구성된 결정 습성을 지칭하고, 여기에 사용된 용어 "침상형의 티타니아 입자"는 침상 TiO2 결정자의 침상 집합체를 의미한다.As used herein, the term “acicular” refers to a crystal habit consisting of radial masses of slender, acicular crystals, and the term “acicular titania particles” as used herein refers to acicular aggregates of acicular TiO 2 crystallites.
일 실시형태에 있어서, 상기 침상형의 티타니아 입자는 특정 조건 하에서, 형태 조절제, 또는 형태 조절제의 혼합물의 존재 하에 수성 용액 내에서 가용성 TiO2 전구체 화합물, 또는 그러한 화합물의 혼합물을 열적으로 가수분해함에 의해 제조된 것일 수 있다.In one embodiment, the acicular titania particles are formed by thermally hydrolyzing a soluble TiO 2 precursor compound, or a mixture of such compounds, in an aqueous solution in the presence of a shape controlling agent, or a mixture of shape controlling agents, under specific conditions. may be manufactured.
일 실시형태에 있어서, 상기 침상형의 티타니아 입자는 루타일(rutile) 상인 것일 수 있다.In one embodiment, the acicular titania particles may be in a rutile phase.
일 실시형태에 있어서, 상기 침상형의 티타니아 입자의 종횡비는 30 : 1 내지 10 : 1 인 것일 수 있다. 종횡비가 30 : 1 초과인 경우 광확산 우세해서 투과 특성이 저하 될 수 있으며, 종횡비가 10 : 1 미만인 경우 투과 특성이 우세하고 광확산 특성이 저하 될 우려가 있다. In one embodiment, the aspect ratio of the acicular titania particles may be 30:1 to 10:1. When the aspect ratio is greater than 30:1, light diffusion is dominant and transmission characteristics may be deteriorated. When the aspect ratio is less than 10:1, transmission characteristics are dominant and light diffusion characteristics may be deteriorated.
일 실시형태에 있어서, 침상형의 티타니아 입자는 연장된, 즉, 막대-형, TiO2 결정자의 정렬된 침상 집합체를 포함하는 것일 수 있다. In one embodiment, the acicular titania particles may include aligned acicular aggregates of elongated, ie rod-shaped, TiO 2 crystallites.
일 실시형태에 있어서, 침상형의 티타니아 입자의 장직경이 10 ㎛ 미만 또는 30 ㎛ 초과에서는 분산과 입자의 배향 특성이 감소될 수 있어, 이방성 광확산 기능을 안정하게 발현시킬 수 없게 될 우려가 있다. 단 직경이 1 ㎛ 미만에서는 광확산의 기능적 역할이 저하되고 10 ㎛ 이상일 경우 확산광 특성이 우세할 우려가 있다.In one embodiment, if the major diameter of the acicular titania particles is less than 10 μm or greater than 30 μm, the dispersion and orientation characteristics of the particles may be reduced, so that the anisotropic light diffusion function may not be stably expressed. . However, if the diameter is less than 1 μm, the functional role of light diffusion is lowered, and if the diameter is more than 10 μm, there is a concern that the diffused light characteristics may prevail.
일 실시형태에 있어서, 상기 침상형의 티타니아 입자의 평균입도는 5 nm 내지 20 ㎛인 것일 수 있다. 상기 침상형 티타니아 입자의 평균입도가 5 nm 미만인 경우 확산특성보단 투과 특성이 우세하며, 20 ㎛ 초과인 경우 분산 및 배향 시키는 것이 곤란 할 수 있다.In one embodiment, the average particle size of the acicular titania particles may be 5 nm to 20 μm. When the average particle size of the acicular titania particles is less than 5 nm, the transmission characteristics are superior to the diffusion characteristics, and when the average particle size is greater than 20 μm, it may be difficult to disperse and orient them.
일 실시형태에 있어서, 상기 침상형의 티타니아 입자는, 상기 침상형 무기입자 분산액 중 5 중량% 내지 20 중량%인 것일 수 있다. 상기 침상형의 티타니아 입자는, 상기 침상형 무기입자 분산액 중 5 중량% 미만인 경우 분산액 내에서 입자의 상대적 비율이 낮아져 분산액의 분산 특성이 저하 될 수 있으며, 점도가 낮아 입자의 침전이 발생 할 가능성이 높다. 20 중량% 이상인 경우, 입자의 응집에 의한 Hardcake이 발생할 가능성이 높다. In one embodiment, the amount of acicular titania particles may be 5% to 20% by weight in the dispersion of acicular inorganic particles. When the acicular titania particles are less than 5% by weight in the dispersion of acicular inorganic particles, the relative ratio of the particles in the dispersion is lowered, which may lower the dispersion characteristics of the dispersion, and the possibility of precipitation of the particles may occur due to the low viscosity. high. If it is 20% by weight or more, there is a high possibility of hardcake caused by particle aggregation.

By causing, it is possible to form composite particles for optically transparent pressure-sensitive adhesive.

일 실시형태에 있어서, 상기 인산계 분산제는, 상기 침상형의 티타니아 입자 100 중량부 대비 10 중량부 내지 30 중량부인 것일 수 있다. 상기 인산계 분산제가 상기 침상형의 티타니아 입자 100 중량부 대비 10 중량부 미만인 경우 침상형의 티타니아 입자의 분산성을 향상시키기 위한 표면 개질 효과가 떨어질 수 있다, 30 중량부 초과하는 경우, 인산계 표면처리제가 용매에 충분히 용해되지 않아 표면 개질 효과가 저하되고, 분산액의 점도가 상승할 수 있다.In one embodiment, the phosphoric acid-based dispersant may be 10 parts by weight to 30 parts by weight based on 100 parts by weight of the acicular titania particles. If the amount of the phosphoric acid-based dispersant is less than 10 parts by weight relative to 100 parts by weight of the acicular titania particles, the surface modification effect for improving the dispersibility of the acicular titania particles may be reduced. If it exceeds 30 parts by weight, the phosphoric acid-based surface Since the treatment agent is not sufficiently dissolved in the solvent, the surface modification effect may decrease and the viscosity of the dispersion may increase.
