A packing container featuring markedly improved slipping property and non-adhering property for its contents. In the packing container filled with a content (7), at least part of the surface that comes in contact with the content (7) is a liquid-permeable surface (1) which holds a lubricating liquid (5) different from the content (7).

An embodiment relates to a multi-layer, biaxially oriented polyester (BOPET) film comprising a food contact substance, wherein the BOPET has a percent release in a retort test after can lamination such that substantially all food contacting the BOPET during the retort test is released. Another embodiment relates to a method comprising applying a food contact material comprising a food contact substance to a multi-layer, biaxially oriented polyester (BOPET) film, wherein the food contact material is prepared at around room temperature without heating.

A coating composition for application to a subsea component or structure includes a cellulose acetate, a plasticizer, a vegetable oil, and an ethylene-based polymer stabilizer that are mixed together. The plasticizer is epoxidized linseed oil. The vegetable oil is selected from the group including vegetable oil and soybean oil. The ethylene-based polymer stabilizer has a pigment carried therein. The ethylene-based polymer stabilizer is low-density polyethylene. The pigment is titanium dioxide and carbon black.

A composition for forming a bio-compatible membrane applicable to building material, such as concrete, cement, etc., to a method of applying said composition for forming a biocompatible membrane, a biocompatible membrane, use of said membrane for various purposes, and to building material comprising said membrane.

A coating having a hydrogel layer of a hydrogel of a polysaccharide and polymer brushes attached to the hydrogel layer. A process for making the coating, having the steps of: a) providing the hydrogel layer on a substrate, b) attaching an initiator having a radically transferable atom on the hydrogel layer and c) reacting monomers with the initiator to form the polymer brushes attached to the hydrogel layer.

A self-healing, scratch resistant slippery surface that is manufactured by wicking a chemically-inert, high-density liquid coating over a roughened solid surface featuring micro and nanoscale topographies is described. Such a slippery surface shows anti-wetting properties, as well as exhibits significant reduction of adhesion of a broad range of biological materials, including particles in suspension or solution. Specifically, the slippery surfaces can be applied to medical devices and equipment to effectively repel biological materials such as blood, and prevent, reduce, or delay coagulation and surface-mediated clot formation. Moreover, the slippery surfaces can be used to prevent fouling by microorganisms such as bacteria.

Marine coatings including cationic polymers hydrolyzable to nonfouling zwitterionic polymers, coated marine surfaces, and methods for making and using the marine coatings.

Thermal Marine Coating System is a bio-inhibitor for a water immersive surface including and not limited to a ship hull, off-shore windmill, buoy, and/or any other aquatic object. The bio-inhibiting action repels micro and macro organisms thereby preventing attachment to a vessel or other aquatic object immersed in seawater and/or freshwater. The coating matrix comprises waxes and a metallic soap very slowly and continuously agitated at constant temperature from blending of ingredients through application onto prepared substrate. The integrity of the matrix is non-porous and long lasting.

The present invention discloses a method of constructing a solid slippery surface, belonging to the technical field of preparation of lubricating materials. The method of constructing a solid slippery surface comprises (1) constructing a metal oxide coating on the surface of a metal substrate by anodic oxidation, and then modifying the metal oxide coating using a low surface energy material to afford a superhydrophobic coating; and (2) fulling mixing photothermal nanoparticles and solid paraffin, followed by infusing the mixture onto the surface of the superhydrophobic coating to afford the solid slippery surface. The preparation method of the present invention is performed in a simple process and is environmentally friendly. The solid slippery surface constructed in the present invention has excellent photothermal and anti-icing performance, making some improvements in the field of copper metal anti-icing.
