Abstract

Abstract The present invention is the formation of solid polymer layers under vacuum. More specifically, the present invention is the use of "standard" polymer layer-making equipment that is generally used in an atmospheric environment in a vacuum, and degassing the monomer material prior to injection into the vacuum. Additional layers of polymer or metal may be vacuum deposited onto solid polymer layers. Formation of polymer layers under a vacuum improves material and surface characteristics, and subsequent quality of bonding to additional layers. Further advantages include use of less to no photoinitiator for curing, faster curing, fewer impurities in the polymer electrolyte, as well as improvement in material properties including no trapped gas resulting in greater density, and reduced monomer wetting angle that facilitates spreading of the monomer and provides a smoother finished surface.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 70 words
A method of making a first solid polymer layer, comprising the steps of: (a) placing a moving substrate into a vacuum chamber, (b) placing a mechanical liquid-monomer spreading apparatus into the vacuum chamber; (c) degassing a first liquid monomer, (d) depositing a first thin layer of the degassed liquid monomer from said liquid-monomer spreading apparatus onto the moving substrate within the vacuum chamber, and (e) curing said first thin layer.
Claim 2
Independent Claim 70 words
A method of making a first solid polymer layer, comprising the steps of: (a) placing a moving substrate into a vacuum chamber, (b) placing a mechanical liquid-monomer spreading apparatus into the vacuum chamber; (c) degassing a first liquid monomer, (d) depositing a first thin layer of the degassed liquid monomer from said liquid-monomer spreading apparatus onto the moving substrate within the vacuum chamber, and (e) curing said first thin layer.
Claim 3
Dependent Claim 22 words
A method as recited in claim 1, further comprising the step of: (a) vacuum depositing metal onto said first solid polymer layer.
Claim 4
Dependent Claim 38 words
A method as recited in claim 1, further comprising the steps of: (a) depositing a second thin layer of a second degassed liquid monomer onto said first solid polymer layer under vacuum, (i) curing said second thin layer.
Claim 5
Dependent Claim 35 words
A method as recited in claim 2, further comprising the steps of: (a) depositing a second thin layer of a second degassed liquid monomer onto said metal under vacuum, (i) curing said second thin layer.
Claim 6
Dependent Claim 18 words
A method as recited in claim 1, wherein said first liquid monomer is a liquid monomer cathode material.
Claim 7
Dependent Claim 27 words
A method as recited in claim 5, wherein a layer of metal is deposited onto said moving substrate in advance of depositing said liquid monomer cathode material.
