优选的,所述基材层的厚度为10微米~200微米之间。
本发明还提供一种光透微纳薄膜的制造方法,包括以下步骤:
步骤一,加工基材层,采用PVC、PET、PC中的任意一种或组合加工基材层;
步骤二,加工微纳结构层,在上述步骤一完成的基材层表面用热压印或紫外压印的方法制作所述微纳结构层;
步骤三,加工纳米颗粒涂敷层,在上述步骤二完成的微纳结构层之上用喷涂或辊涂的涂布方法涂一层纳米颗粒涂层形成纳米颗粒涂敷层;
步骤四,在所述基材层远离微纳结构层的另一端涂布透明的透明光学可移胶,再复合一层离型膜;

附图说明
图1为本发明提供的光透微纳薄膜的结构示意图;
图2为本发明提供的光透微纳薄膜中的微纳结构层的结构示意图。
具体实施方式
以下将参考附图并结合实施例来详细说明本发明。需要说明的是,在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。为叙述方便,下文中如出现“上”、“下”、“左”、“右”字样,仅表示与附图本身的上、下、左、右方向一致,并不对结构起限定作用。
如图1~2所示,本发明提供的一种光透微纳薄膜包括基材层1、设于所述基材层1一端的透明光学可移胶2,设于所述基材层1另一端的微纳结构层3,在所述透明光学可移胶2远离微纳结构层3的一端设有离型膜4,在所述微纳结构层3远离透明光学可移胶2的一端设有纳米颗粒涂敷层5。
所述基材层1采用PVC、PET、PC等透明聚合物材料的一种或组合加工形成。
PVC(Polyvinyl chloride),聚氯乙烯,在过氧化物、偶氮化合物等引发剂;或在光、热作用下按自由基聚合反应机理聚合而成的聚合物。
PET(Polyethylene terephthalate),聚对苯二甲酸乙二醇酯,由对苯二甲酸二甲酯与乙二醇酯交换或以对苯二甲酸与乙二醇酯化先合成对苯二甲酸双羟乙酯,然后再进行缩聚反应制得。属结晶型饱和聚酯,为乳白色或浅黄色、高度结晶的聚合物,表面平滑有光泽。
PC(Polycarbonate)PC,聚碳酸酯塑料,是非晶态聚合物,在熔化和冷却后变成透明的玻璃状物,具有优良的光学和力学性能。
上述材料都具有透明度高,可阻挡紫外线,光泽性好的特性。
所述基材层1的厚度为10微米~200微米之间。如选用PET的材料,其厚度则为150微米。
所述透明光学可移胶2是一种预成型的胶贴,为具有一定柔韧性的高透明胶,方便贴附于大幅玻璃等载体上。
所述微纳结构层3都过所述微纳结构层3都过在基材层1上用纳米压印的方法制成,其可有效管理光线传播方向,有效屏蔽照射到屏幕的干扰光线环境光的干扰,不会减少传播只至观察者眼中的机会,而相对增加投影图像强度。在所述微纳结构层外层涂布有纳米颗粒层。
上排布设有多个凸点32和凹点33,其中,n个凸点32中设置至少一个凹点33,n为大于三的正整数。在本实施例中n为4。4个凸点32和一个凹点33形成一个光学结构区31,所述微纳结构层3由多个光学结构区31组成。
如图2所示,所述光学结构区31的正投影为规则的正多边形。每个所述光学结构区中,n个凸点32和一个凹点33构成棱锥结构。所述棱锥结构由四个不等面的三角面构成。在其它实施例中,所述棱锥结构也可以由四个或以上或小于四个的等面或不等面的三角面构成。
每个所述光学结构区31中的凹点33位于该光学结构区31正多边形中心向一侧偏置上。在本实施例中,向图2中的左侧偏置。每个所述光学结构区31中,4个凸点32和一个凹点33构成棱锥结构。该呈棱锥的偏置结构的结合,可让微纳结构层具有较好的透光性的同时又能清晰看到激光投影机投放在其上的图像。
每个所述光学结构区31中,4个凸点32在一个凹点33的周边设置,相邻的两个光学结构区31共用一侧凸点32。
所述纳米颗粒涂敷层5内为多层包覆结构的纳米颗粒,其可对特定波长光线具有吸收和散射作用。所述的纳米颗粒涂敷层对波长近似650nm,530nm,450nm的入射光线具有选择性散射和折射作用。
本发明还提供一种光透微纳薄膜的制造方法,包括以下步骤:
步骤S1,加工基材层,采用PVC、PET、PC中的任意一种或组合加工基材层。
步骤S2,加工微纳结构层,在上述步骤一完成的基材层表面用纳米压印的方法制作所述微纳结构层。所述纳米压印法为加温加压的热压印法或紫外光辐射固化的紫外成型方法。纳米压印的法即通过专用模具在基材层表面压印成多个棱锥形的光学结构区。
步骤S3,加工纳米颗粒涂敷层,在上述步骤二完成的微纳结构层之上用喷涂或辊涂的涂布方法涂一层纳米颗粒涂层形成纳米颗粒涂敷层。所述纳米颗粒涂层包括纳米颗粒材料和聚合物材料组合构成,所述聚合物材料为热风干燥聚合物涂料或紫外光辐射固化。所述纳米颗粒材料为多层包覆结构的纳米颗粒材料,其为金属氧化物和/或半导体氧化物。纳米颗粒对特定波长的光波具有吸收和散射的作用。
在本实施例中,纳米颗粒采用二氧化硅、二氧化钛以及银包覆中任意两种或三种组合,这种组合材料对投影机投送的图像光波在红(650nm)绿(530nm)兰(450nm)有很高的响应值,而对环境中的其它杂散光基本不会吸收和散射。
步骤S4,在所述基材层远离微纳结构层的另一端涂布透明的透明光学可移胶,再复合一层离型膜。
步骤S5,完成光透微纳薄膜的加工。
