Disclosed herein are finished products, methods, compositions and kits for derivatizing plastic (e.g., “polymer”) surfaces in a manner that renders the surfaces appropriate for various downstream applications. For example, flow cells incorporating modified plastic surfaces provide greatly enhanced stability for retention of attached chemical species such as polypeptides and nucleic acids.

Polymeric materials are described which have a bioflavonoid coating, the bioflavonoid content of the coating comprising at least naringin and neohesperidin. The use of such coated polymeric materials is also described as well as the process for making the coated polymeric materials.

A fiber-reinforced composite material includes a matrix resin, and reinforcing fibers, in which the matrix resin includes a polyaryl ketone resin and a resin having a nitrogen atom in a repeating structural unit. A surface of the fiber-reinforced composite material includes a portion in which a contact angle with water is 60° or less.

This invention relates to biodegradable starch-based pellets which foamable by irradiation, which are particularly suitable for the manufacture of foam articles, characterised in that they have a porous structure with a low porous external skin. This invention also relates to foam articles obtained from these.

A method for surface treatment of a silicone rubber includes: providing the silicone rubber bearing a polar group on a surface of the silicone rubber, and applying a multifunctional compound to the surface of the silicone rubber bearing the polar group to allow the multifunctional compound to react with the polar group to form a coating.

A polymer-based spherical powder preparation device and preparation process are disclosed. The preparation device comprises a mill milling system and an inductively coupled plasma powder spheroidization system. The mill milling system of the preparation device can achieve ultra-fine grinding of the material at room temperature by applying strong extrusion, shear and circumferential stress to the material; and the inductively coupled plasma powder spheroidization system using high temperature plasma as high temperature heat source, the polymer powder can be heated uniformly, and the melting and cooling rate is fast, so the spheroidization can be completed in a short time. The preparation process of polymer based spherical powder was integrated and continuously produced by the preparation device.

The present invention relates to a method for modifying the surface of a polymer substrate. Specifically, the present invention provides a method for modifying the surface of a polymer substrate using a plasma treatment, a hydrophilic primer and a coating agent including a hydrophobic fluorine compound.

A method of pre-treating plastic using plasms is disclosed. The plasma is applied to plastic in an atmosphere such as oxygen that encourages formation of functional groups on an otherwise inert plastic surface. The functional groups such as hydrogen group, carboxyl group, and formyl group are introduced on the surface of the recycled plastics. This allows the use of plastic to replace part of the sand aggregate in mortar, resulting in a more environmentally friendly mortar.

A manufacturing method of a resin sheet that is capable of being deformed, covering a front surface of a substrate, and protecting the substrate and that is capable of curing by being given energy from the external includes a liquid resin disposing step of disposing a liquid resin capable of curing by being given the energy from the external on a flat surface and a surface curing step of forming a resin coat layer through curing only an outer circumferential surface of the liquid resin by giving the energy with such intensity that the whole of the liquid resin does not cure to the liquid resin from the external and leaving the liquid resin that is not cured inside the resin coat layer.
