Embodiment Construction

[0036] The preferred embodiments of the invention will be further described in detail below.

[0037] Condoms include male and female condoms. In view of the fact that sexual behavior is mostly dominated by men, male condoms are the main products on the market. As a typical application, the following examples refer to male condoms, unless there are specific instructions for female condoms in some places.

[0038] A method for manufacturing a condom containing nanoscale materials of an embodiment, comprising the steps of:

[0039] S1, placing the condom base in a plasma environment so that the plasma is fully in contact with the condom base, thereby performing pretreatment on the condom base.

[0040] The formed condom matrix material is subjected to plasma pretreatment and surface modification, so that the combination degree of the fluoride and the condom matrix material can be improved.

[0041] S2, forming a layer of fluoride with nanoscale particle size on the surface of...

Abstract

The invention discloses a condom containing a nano-scale material and a manufacturing method for the condom. The manufacturing method comprises the following steps: S1, placing a condom base body into a plasma environment to pre-process; S2, forming a layer of fluoride with a nano-scale grain size on the surface of the condom base body. The condom with a nano-scale fluoride outer layer is small in bore diameter and can be used for blocking virus with a diameter of tens of nanometers. The polytetrafluoroethylene PTFE has a friction coefficient of only 0.04 and high self-lubrication, so that physical lubricating oil is not required to be especially added to a condom body.

Description

【Technical field】 [0001] The invention relates to a condom, in particular to a condom containing nanometer material and a manufacturing method thereof. 【Background technique】 [0002] The preparation methods of commercially available condoms are mostly based on a single material and a single dipping process. Whether it is latex, polyisoprene, polyurethane, or silica gel, these polymer materials have large pore sizes and high porosity, and there are natural pores ranging from hundreds or even thousands of nanometers. It is significantly effective in blocking large particle sizes, such as human sperm with a head width of about 3000 nanometers, that is, contraception. However, it is not so reliable when blocking viruses with smaller particle sizes in body fluids, such as hepatitis B virus with a diameter of 42 nanometers, human papillomavirus with a diameter of 50-55 nanometers, HIV with a diameter of 120 nanometers, and even smaller particles. up. According to the results o...
