Provided is a preparation method for a double-layer working medium target tape with a plasma-enhanced interfacial bonding force for a micro laser thruster. Aiming at the problem that in an existing micro laser thruster, when a working medium is ablated by a laser beam, due to a weak interlayer interfacial bonding force between a transparent film substrate and the coating working medium, sputtering or bulging occurs, which remarkably reduces propulsive performance, a method for treating a surface of a transparent film substrate with a low-temperature plasma is used to increase surface energy of a film and an adhesive force of a working medium layer on a surface of the film, thereby enhancing the interlayer interfacial bonding force. According to the method in the present disclosure, the transparent film substrate is treated with the low-temperature plasma.

Compositions and methods for producing smoke suppressants are disclosed. The smoke suppressant molecularly encapsulates a naturally-occurring inorganic substrate, such as expanded volcanic ash.

components (i), (ii) and (iii) and the respective proportions thereof being chosen such that the support equipped with the coating can be elongated without the appearance of cracks in the coating.

A method for modifying a polymeric surface is disclosed. The polymeric surface is activated utilizing atmospheric pressure plasma. An atom transfer radical polymerization initiator is then coupled to the activated surface. A monomer is then polymerized on the activated surface utilizing an activators regenerated by electron transfer (ARGET) atom transfer radical polymerization (ATRP) process. The method enables brush-modification of the polymeric surface, even if the polymeric surface is substantially chemically inert. By way of example, the method enables a chemically inert, substantially hydrophobic polymer surface to be functionalized with substantially hydrophilic polymer brushes. The methods of the present disclosure have general applicability to a myriad of implementations where tunable surface chemistry is advantageous, such as filtration membranes, marine surfaces, and medical devices seeking a biocompatible coating.

The process for preparing contact lens with films by plasma enhanced chemical vapor deposition to apply plasma modification on contact lens to form hydrophilic functional groups on the surface of contact lens, and then respectively heating PEGMA and NVP into a gaseous state, and depositing the gaseous PEGMA and NVP on the substrate by means of PECVD so as to form the thin film on the substrate. By means of the thin film, the contact lens can reveal stable hydrophilicity and anti-fouling properties, so when the patient wear the contact lens, he or she does not feel uncomfortable foreign body sensation, significantly reducing the deposition of proteins and corneal infection risk.

In a laminate film 1 including a substrate 2, a polyurethane layer 3 formed on the substrate 2, and a metal vapor deposition layer 4 formed on the polyurethane layer 3, a coating liquid is applied on the substrate 2 and dried to produce the polyurethane layer 3. The coating liquid contains a water dispersible polyisocyanate and a polyurethane dispersion containing polyurethane resin produced by reaction of an isocyanate group-terminated prepolymer with a chain extender. The isocyanate group-terminated prepolymer is produced by reaction of a polyisocyanate component including xylylene diisocyanate and/or hydrogenated xylylene diisocyanate and a polyol component including diol having 2 to 6 carbon atoms and an active hydrogen group-containing compound containing a hydrophilic group.

Elastomeric components, such as a shoe outsole, are treated with a plasma application to clean and activate the elastomeric component. The application of plasma is controlled to achieve a sufficient surface composition change to enhance adhesion characteristics while not adversely physically deforming the elastomeric component. The plasma treatment is applied to increase carbonyl functional group concentrations within an altered region of the elastomeric component to within at least a range of 2%-15% of carbon atomic percentage composition. The cleaning and activation is controlled, in part, by ensuring a defined height offset range is maintained between the elastomeric component and the plasma source by a generated tool path. The elastomeric component may then be adhered, with an adhesive, to another component.
