The invention relates to a method for producing a carrier layer with a hydrophilic polymeric nanocoating wherein a polymeric carrier layer is produced with filaments of polymer material(s). Further the hydrophilic polymer nanocoating is applied by means of a low pressure plasma polymerization process using organic precursor monomers onto the polymeric carrier layer and/or composite membrane. Additionally, the invention relates to a carrier layer with a polymeric hydrophilic nanocoating.

This application relates to omniphobic materials which are physically and chemically modified at their surface to create hierarchically structured materials with both nanoscale and microscale structures that provide the omniphobic properties. Methods of making such omniphobic surfaces with hierarchical structures and uses thereof, including as flexible films that repel contaminants are also disclosed in the application.

A regenerable antimicrobial coating with long-lasting efficacy for use in medical applications including implants, medical instruments or devices, and hospital equipment is disclosed. The regenerable antimicrobial coating is derived from a polymer doped with a metal derivative which has been exposed to vapor-phase hydrogen peroxide, wherein hydrogen peroxide is sequestered in or on the doped polymer.

The present invention relates to a method for preparing a porous polymer film having a controlled pore depth, and a porous polymer film prepared thereby. A method for preparing a porous polymer film according to the present invention allows the pore depth of a porous film to be controlled simply and at a low cost, and thus allows adjustment of the light reflectance of the prepared film. A large-area film can be prepared by means of a simple method and thus can be applied to various industry fields. Films having different reflectance can be prepared and thus can be applied as low-reflection and high-reflection films for solar cells, and also as a low-reflection or high-reflection thin polymer film in the construction field or material and equipment field.

A method of producing a film-attached resin base may include supplying a surface treatment gas including at least fluorine gas to a resin base including reinforcing fibers so that embrittled regions are formed in a surface of the resin base and the reinforcing fiber present near the surface of the resin base is modified at least partially; removing at least the embrittled regions so that an uneven surface is formed on the resin base and the reinforcing fiber is at least partially exposed in the uneven surface; and forming a film onto the uneven surface of the resin base.

An object is to provide a method for manufacturing a spectacle lens having an excellent cut ratio of light having a wavelength of 420 nm and further having an excellent appearance, and a spectacle lens.

[1] A method for manufacturing a spectacle lens, including a step of immersing a substrate in an immersion liquid containing an indole-based UV absorber, and [2] a spectacle lens including a substrate impregnated with an indole-based UV absorber by a dyeing method.

A method for producing a carrier layer with a hydrophilic polymeric nanocoating wherein a polymeric carrier layer is produced with filaments of polymer material(s). The hydrophilic polymer nanocoating is applied with a low pressure plasma polymerization process using organic precursor monomers deposited onto the polymeric carrier layer and/or composite membrane. Additionally, a carrier layer includes a polymeric hydrophilic nanocoating.

The present invention relates to a process for texturing surfaces providing the latter with superhydrophobic, superoleophobic, superhydrophilic or even superoleophilic properties. This process comprises i) a step of texturing the surface (via the deposition of nanoparticles of different sizes); ii) a step of curing the surface thus textured (with a curing agent); and, optionally, a step of modifying the properties of the surface with perfluorinated (and therefore hydrophobic) molecules. This process is suitable, inter alia, for treating transparent and/or heat-sensitive materials and surfaces. Specifically, none of the steps of the process use a temperature higher than 100 C. Thus, the process of the invention is particularly suitable for treating transparent surfaces composed of non-mineral materials, such as polycarbonate for example, as it wilt affect neither their transparency nor their optical properties.

A method for applying a sulfonation treatment to a thermoplastic part includes installing a gas sulfonation assembly on one or more surfaces of the thermoplastic part by forming a vacuum bag on the one or more surfaces. The vacuum bag forms a sealed cavity between the vacuum bag and a treatment portion of the one or more surfaces. The method further includes drawing a vacuum in the sealed cavity with the gas sulfonation assembly, directing a sulfonating gas into the sealed cavity with the gas sulfonation assembly to sulfonate the treatment portion, removing the sulfonating gas from the sealed cavity with the gas sulfonation assembly, removing the gas sulfonation assembly from the thermoplastic part, applying a neutralizing agent to the treatment portion, and applying at least one coating to the treatment portion.
