Abstract: 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.

Abstract: The attachment and proliferation of antibiotic resistant, biofilm-forming bacteria to oft-handled material surfaces has emerged as a growing concern, particularly in the biomedical, healthcare and food packaging industries. UV-curable phosphoniums bearing benzophenone anchors have been synthesized with a variety of alkyl, aryl, and fluoroalkyl functional groups at phosphorus to probe their efficacy as thermally stable antimicrobial additives in plastics or as surface coatings. In an embodiment, a phosphonium compound having the following formula has been synthesized:




in which R is a phosphine group substituted with alkyl, aryl, substituted alkyl, substituted aryl, heteroalkyl or any combination thereof. These materials maintained the ability to kill biofilm-forming bacteria even after being subject to abrasion processes, demonstrating the potential to serve as long-term antimicrobial materials.

Abstract: A method and apparatus for applying a faux wood grain finish to plastic architectural plastic boards. The method employs a climate-controlled area for denibbing of boards to prepare a surface and a sprayer to achieve a desired depth of color. A wiper spreads the sprayed on material to form a faux grain finish which may include faux wood knots. The boards are directed through a combination infrared and convection oven having independent curing zones providing specific drying profiles. Once cured, the boards are cooled with forced air cool down fans and transferred into a climate-controlled area for applying a topcoat. The topcoat board is passed through an oven set to a defined temperature for curing and cooled down with forced air cool down fans before packaging and shipping.

Abstract: Functionalized copolymers of isoolefins and conjugated diolefins, methods of preparing the copolymers, and their use as compatibilizers are disclosed. The diolefin monomer units of the co-polymer are modified at the C═C double bond along the backbone of the copolymer to include an oxygen containing functional group such as epoxide, ester or alcohol. The functionalized copolymers improve the wettability of a non-hydrophilic surface towards hydrophilic polymer and allows for the formation of homogenous layers of the hydrophilic polymers. In particular, the spreading of a hydrophilic polymer on a non-hydrophilic substrate is facilitated by applying the co-polymers as an interfacial layer between the two incompatible materials. The resulting coated substrates exhibit resistance to protein adsorption and cell growth after grafting. The co-polymers are especially suited in the coating of biomedical devices where a high degree of uniformity of the coated surface is required.
