实施例1
如图1所示，本发明提供的一种防蓝光膜100，包括依次设置的二氧化硅基底1、金属纳米颗粒结构2、石墨烯层3以及透明保护层4。其中所述金属纳米颗粒结构2由粒径均匀的金属纳米颗粒21组成，所述金属纳米颗粒结构2设置于所述二氧化硅基底1上；所述石墨烯层3覆盖于所述金属纳米颗粒结构2上；所述透明保护层4设置于所述石墨烯层3上面。
其中所述金属纳米颗粒21为Au以及Ag中的至少一种。其中所述纳米颗粒21的直径范围为30-80纳米。当光线入射到由贵金属构成的纳米颗粒上时，如果入射光子频率与贵金属纳米颗粒或金属岛传导电子的整体振动频率相匹配时，纳米颗粒或金属岛会对光子能量产生很强的吸收作用，就会发生局域表面等离子体共振。金属纳米颗粒21在石墨烯层3中，受到光激发时，产生局域等离子体共振，会增强石墨烯对波长为330-450纳米的高能短波的吸收，从而能够有效的防止伤害人体的高能短波蓝光的射出。如果所述纳米颗粒21的直径超出此范围，将会影响金属纳米颗粒21在石墨烯层3中形成局域等离子体共振，降低防蓝光膜100的效果。
其中所述透明保护层4厚度范围为50-200纳米。如果透明保护层4的厚度小于50纳米，会给防蓝光膜100的制造增加难度，增加生产成本；如果透明保护层4的厚度大于200纳米，会影响出光效果。
如图2、图3所示，本发明提供的一种防蓝光膜的制备方法。其中包括：步骤S1，提供二氧化硅基底；步骤S2，将金属纳米颗粒21和嵌段共聚物22共同分散于一甲苯溶剂中，将分散好的甲苯溶剂旋涂于步骤S1中所述二氧化硅基底1上，烘干所述分散好的甲苯溶剂形成膜层，通过等离子体刻蚀的方法刻蚀所述的膜层，去除所述的膜层中的嵌段共聚物22，在步骤S1中所述的二氧化硅基底上形成金属纳米颗粒结构2；步骤S3，通过化学气相沉积的方式在步骤S2中所述的金属纳米颗粒结构2上制备石墨烯层3；步骤S4，在所述石墨烯层3表面旋涂聚甲基丙烯酸甲酯溶液形成透明保护层4；步骤S5，烘干所述透明保护层4形成防蓝光膜100。
其中所述嵌段共聚物22为聚(苯乙烯)-b-聚(2-乙烯基吡啶)，其可以很好地避免金属纳米颗粒21的团聚，从而达到金属纳米颗粒21在甲苯溶液中的均匀分散。其中步骤S2中的等离子刻蚀，是干法刻蚀中最常见的一种形式，其原理是暴露在电子区域内的气体形成等离子体，由此产生的电离气体原子和释放高能的电子组成的气体，从而形成了等离子或离子，电离气体原子通过电场加速时，会释放足够的力量与表面驱逐力紧紧粘合材料或刻蚀表面。其中所述等离子体刻蚀可以采用H2以及Ar中的至少一种。
其中步骤S3中所述的化学气相沉积技术是利用气相中发生的化学过程，在工件表面形成功能性或装饰性的金属、非金属或化合物涂层。
如图4所示，本实施例的一种显示器件，包括依次设置的外框200、反射板300、发光二极管400、扩散板500、扩散片600、增亮膜700、液晶屏800以及防蓝光膜100。所述反射板300设置于所述外框200内，用于将发光二极管400发出的光向上反射，提高光的使用效率；所述发光二极管400设置于所述反射板300上；所述扩散板500设置于所述发光二极管400上；所述扩散片600设置于所述扩散板500上；所述增亮膜700设置于所述扩散片600上；所述液晶屏800设置于所述增亮膜700上；所述防蓝光膜100设置于所述液晶屏800上。防蓝光膜100的设置可以有效的吸收高能短波蓝光，降低对眼底视网膜的伤害，避免皮肤产生黄斑、雀斑，会减轻眼睛近视程度，降低视觉疲劳感。
