Abstract
A plastic member, for example, a hydrocarbon-based transparent polymer molded product is subjected to fluorination processing in a fluorine gas within a reaction device 8 to fluorinate only a surface layer thereof. Thus, a refractive index can be lowered, a surface reflection can be lowered, and light transmittance of a base material can be improved.
Claims24
A method of manufacturing a transparent member, comprising a step of preparing a member having a transparent hydrocarbon polymer at least on a surface portion thereof and a step of exposing a surface of the transparent hydrocarbon polymer to an atmosphere containing a fluorine gas to thereby fluorinate at least a part of the transparent hydrocarbon polymer.
(canceled)
A method of manufacturing a transparent member, including a step of forming a hydrocarbon material film on a substantially transparent plastic substrate and a step of bringing a surface of the hydrocarbon material film into contact with an atmosphere containing a fluorine gas to fluorinate at least a part of the hydrocarbon material film.
(canceled)
A method of manufacturing a transparent member, including a step of exposing a surface of at least a part of a transparent hydrocarbon polymer member to vaporized hydrocarbon or liquid hydrocarbon to form a hydrocarbon layer having a composition different from that of the polymer base material and a step of exposing the hydrocarbon layer to an atmosphere containing a fluorine gas to fluorinate the hydrocarbon layer.
