Hydrogels based on vinyl-caprolactam
The invention relates to a hydrogel based on vinyl caprolactam, with or without additional monomers, and at least two crosslinkers. The invention also relates to a method for obtaining said material and to the use thereof to culture cells/engineer cell monolayers, as well as supports for cell culture and transplant.
ENZYME-MEDIATED FREE RADICAL INITIATING SYSTEMS FOR THE PRODUCTION OF HYDROGELS AND CONTROLLED RADICAL POLYMERIZATION PROCESSES
The present disclosure describes, in part, an enzyme-mediated radical initiating system and methods of using the system to produce polymers, including polymeric hydrogels, at ambient conditions.
High temperature polyketone copolymers
Compositions and methods for amorphous high temperature polyketone polymers incorporating 2H-benzimidazol-2-one with dihalobenzophenone and bis(halobenzoyl)benzene as comonomer units are described herein. The polyketones polymers have advantageous properties, particularly in terms of high glass transition temperatures (T.sub.g), inherently flame resistance, good mechanical properties at elevated temperature, chemical resistance and dimensional stability in wet environment. The polymers are suitable for manufacturing high temperature molded systems and other articles of manufacture via injection molding, extrusion, compression molding, coating, blow molding, thermoforming, rotational molding and additive manufacturing.
Photonic crystal structure and anti-forgery color conversion film comprising same
An anti-forgery color conversion film includes a photonic crystal structure whose color is converted by an external stimulus such as a breath. The photonic crystal structure includes a first refractive index layer including a first polymer exhibiting a first refractive index; and a second refractive index layer which is alternately laminated with the first refractive index layer and includes a second polymer exhibiting a second refractive index. A consumer who purchases an article including the color conversion film may easily distinguish the authenticity of the article.
Methods for preparing superhydrophobic nano-microscale patterned films
The present application discloses methods for preparing superhydrophobic nano-microscale patterned films, films pre-pared from such methods and uses of such films as superhydrophobic coatings. The superhydrophobic nano- microscale patterned films comprise high aspect ratio nanoparticles such as boron nitride nanotubes (BNNTs) and/or carbon nanotubes (CNTs).
METHOD FOR MANUFACTURING CARBON NANOTUBE-BLENDED AGGREGATE
A method for manufacturing a carbon nanotube-blended aggregate of the present invention includes the steps of: (1) providing an aqueous solution of a water-soluble polymer having a concentration of 0.005 to 3.0% by mass; (2) impregnating carbon nanotubes with the aqueous solution of the water-soluble polymer in a proportion of 400 to 1,000 parts by mass relative to 100 parts by mass of the carbon nanotubes to prepare a wet aggregate; (3) shear-crushing the wet aggregate to obtain an aggregate of crushed products and (4) drying the aggregate of the crushed products to obtain a carbon nanotube-blended aggregate containing the water-soluble polymer.
System and method for adjusting carbon dioxide concentration in indoor atmospheres
An electrochemical device suited to modifying a carbon dioxide concentration in an interior space includes a cathode chamber with an inlet which receives a feed gas containing carbon dioxide. A reduction catalyst layer in the cathode chamber reduces carbon dioxide in the gas to form an ionic carrier species. An anode chamber with an outlet outputs a gas comprising carbon dioxide. A solid electrolyte membrane spaces the anode chamber from the cathode chamber and transports the ionic carrier species between the cathode chamber and the anode chamber. The membrane includes an ionic liquid. An oxidation catalyst layer in the anode chamber oxidizes the ionic carrier species to form carbon dioxide. A voltage source provides a voltage difference across the membrane.
MULTI-FUNCTION DIFFUSION FILM AND DIFFUSION PLATE CONTAINING THE SAME
A diffusion film is provided, including a matrix material including a reaction product of following components: a polythiol, a polyolefin, and a crosslinking agent having thiol and alkenyl functional groups; a photoluminescence material including at least a quantum dot or at least a fluorescent powder; and light diffusion particles including organic polymer particles and/or inorganic particles.
