CN - 19.01.2005

国际分类 A62D 7/00 申请号 03148843.9 申请人 Wang Rui 发明人 Wang Rui

一种纳米防非典口罩及隔离服，系用渗透浸渍纳米粒子的覆盖型纳米布制成。本发明选用能与病毒蛋白快速有效结合并且对人体无毒性的高分子多糖作为制作纳米多糖胶体的材料，纳米多糖胶体中纳米粒子的平均粒径小于100纳米，把普通非纳米布在纳米多糖胶体中浸渍烘干而成覆盖型纳米布，用4层覆盖型纳米布和2层普通非纳米布迭合成一体的复合布料制成的口罩及隔离服，对病毒(包括SARS冠状病毒)有极强的吸附隔离功能，可有效防止病毒进一步被动吸入机体，并具有良好的透气性能。

2.101130128口罩及/或衣服过滤(透气)系统

CN - 27.02.2008

国际分类 A62B 23/06 申请号 200710095962.X 申请人 Shanghai Zhongce Industries Co., Ltd. 发明人 Lin Mingyao

本发明涉及一种口罩及/或衣服过滤(透气)系统，属于纳米口罩及衣服和过滤技术领域。目前口罩及/或衣服过滤系统种类很多，使用材料包含布头，活性炭，不织布等等，但是现在口罩存在制造困难，效果不好，无法满足部分要求如SARS病毒及其他较小细菌，随着纳米技术的进步研究人员获得纳米过滤材料(片，膜片，卷)，纳米孔的大小1－5000纳米可以进行调整。为解决现有口罩制造困难，过滤速度慢，制造难的缺点，本发明在口罩及/或衣服安装多孔径纳米过滤材料(片，膜片，卷)，本发明具有过滤系统结构简单，过滤颗粒小(细菌，病毒都可以使用)，透气好，过滤效果好的优点。

国际分类 A62B 7/10 申请号 3105937 申请人 CHE' NAIDOO, ERIN 发明人 CHE' NAIDOO, ERIN

A face mask is provided. The face mask comprising a mask body, which includes a margin, and straps attached to the mask body proximate the margin for releasably retaining the mask on a user's face, the mask body including: an inner layer, which is a breathable material with interstitial spaces, and which has an inner surface and an outer surface; and a graphene layer which abuts the outer surface and is functionalized with a plurality of silver nanoparticles, to provide a functionalized graphene layer. Afunctionalized graphene mask insert is also provided.

4.3101797OPTICALLY TRANSPARENT FACE MASK FOR PROTECTING A USER FROM AIRBORNE PATHOGENS

CA - 16.09.2021

国际分类 A62B 23/00 申请号 3101797 申请人 HERRING, RODNEY 发明人 HERRING, RODNEY

A face mask comprising an optically transparent or optically semi-transparent mask body is provided. The face mask includes a periphery about an edge of the optically transparent or optically semi-transparent mask body and straps which are attached to the mask body proximate to the periphery or attached to the periphery for releasably retaining the mask on a user's face, the mask body including: an inner layer, which is an optically transparent or optically semi-transparent material with a plurality of passageways therethrough, and which has an inner surface and an outer surface; and a fiberglass fabric layer which abuts the outer surface of the inner layer and which comprises fiberglass ribbons. The fiberglass fabric may be functionalized with a visible light photocatalyst, which may be low iron oxide, iron-doped titanium dioxide.
