Description

一种快速加热的防病毒玻璃及其制备方法
技术领域
本发明涉及功能玻璃技术领域，具体是一种快速加热的防病毒玻璃及其制备方法。
背景技术
冠状病毒于1937年首先在鸡身上分离出来。1965年，分离出第一株人的冠状病毒。由于在电子显微镜下可观察到其外膜上有明显的棒状粒子突起，使其形态看上去像中世纪欧洲帝王的皇冠，因此命名为“冠状病毒”。
自发现以来，冠状病毒就对人类的健康产生了严重的威胁，2003年影响全球的严重急性呼吸综合征（SARS）、2012年影响全球的中东呼吸综合征（EMRS-CoV）及2019年12月以来影响全球的新型冠状病毒（2019-nCoV）均对全球人类的健康及经济造成了重大的影响。
冠状病毒对热感，因此可对存在病毒的物体表面进行加热处理来杀死病毒，传统的电热玻璃为在夹层玻璃中间膜一侧嵌入极细的钨丝或铜丝等金属加热丝，这种方法处理的电热玻璃存在加热慢、加热不均匀及透过率不高的缺点。
发明内容
本发明的目的在于提供一种快速加热的防病毒玻璃及其制备方法，该玻璃能够实现快速加热的目的，加热均匀，同时保证玻璃的透过率；并且制备方法简单，易于实现。
本发明解决其技术问题所采用的技术方案是：
一种快速加热的防病毒玻璃，包括玻璃基底，玻璃基底顶面由下至上依次层叠有石墨烯层、金属网格层、透明氧化物导电层与抗氧化层；金属网格层的网孔孔径为0.5～2µm；所述玻璃基底与石墨烯层的一侧边缘之间夹设有第一电极，透明氧化物导电层与抗氧化层的一侧边缘之间夹设有第二电极。
进一步的，所述玻璃基底为厚度0.12～0.33mm的超薄玻璃。
进一步的，所述金属网格层采用的金属为钨、镍、铝、银或金。
进一步的，所述透明氧化物导电层为ITO薄膜、AZO薄膜或FTO薄膜。
进一步的，所述抗氧化层为SiO2、Al2O3或AlN，抗氧化层的厚度为20～50 nm。
进一步的，透明氧化物导电层为ITO薄膜时的厚度为20～50nm，透明氧化物导电层为AZO薄膜时的厚度为200～400nm。
本发明还提供一种快速加热的防病毒玻璃的制备方法，包括以下步骤：
S1、清洗玻璃基底，去除玻璃基底表面的污物；
S2、将第一电极封接在玻璃基底的顶面边缘；
S3、采用旋涂法在玻璃基底顶面胶体制备石墨烯层及单层聚苯乙烯微球，聚苯乙烯微球均匀分布于石墨烯层上，使石墨烯层的表面形成一组圆弧形凹陷；
S4、通过磁控溅射工艺，在步骤S3完成的表面镀制金属；镀制金属采用钨、镍、铝、银或金；
S5、去除聚苯乙烯微球，得到金属网格层；金属网格层的网孔与石墨烯层的圆弧形凹陷一一对应；
S6、通过磁控溅射工艺，在金属网格层顶面制备透明导电氧化物膜层；透明氧化物导电层为ITO薄膜、AZO薄膜或FTO薄膜；
S7、将第二电极封接在透明导电氧化物膜层的顶面边缘；
S8、在透明导电氧化物膜层上镀制抗氧化层，抗氧化层为SiO2、Al2O3或AlN，抗氧化层的厚度为30～50 nm；得到快速加热的防病毒玻璃。
进一步的，步骤S1的玻璃基底采用厚度0.12～0.33mm的超薄玻璃。
进一步的，步骤S3所述的胶体为石墨烯与聚苯乙烯微球的混合胶体，石墨烯与聚苯乙烯的质量比为1:50-100；聚苯乙烯微球的粒径为0.5～2µm。
进一步的，步骤S5采用四氢呋喃或甲苯有机溶剂超声清洗去除聚苯乙烯微球，超声清洗时间0.2～0.5h。
本发明的有益效果是：
一、石墨烯层、金属网格层和透明导电氧化物层的结合，能有效的降低整个膜系的电阻，通过电极进行电加热时，在电压和加热时间不变的情况下，根据焦耳定律Q=UIT，电阻降低，电流增大，进而产生的热量增加，能快速加热玻璃基底，杀死病毒。
二、通过石墨烯层、金属网格层和透明导电氧化物层的组合膜系结构，能够保证玻璃的透过率。
三、抗氧化层的增加能有效增加整个防病毒玻璃的使用寿命。
