摘要:A method for a synthesis of a polymer containing multiple epoxy groups includes steps of: under protection of nitrogen or argon, with a photosensitive free radical initiator under an ultraviolet light irradiation, initiating a mixture of a dithiol compound and alkynyl glycidyl ether or other alkynyl-containing compounds to proceed a thiol-yne polymerization, so as to obtain the polymer. The number of the epoxy groups is able to be adjusted through changing a type of a dithiol monomer, a mixing ratio of the dithiol monomer, and a mixing ratio between the alkynyl glycidyl ether and other alkynyl compounds. The present invention has advantages of: fast reaction, convenient process, easy post-processing, a large number of the epoxy groups, and adjustable and controllable content. The obtained polymer has a wide potential application in fields of coating, adhesive, ink, encapsulating material, resin for composite material, additive, high performance material, function material, and so on.

权利人:CORNING INC
摘要:A method for making oligomers is described. The method includes reacting a polyol with a precursor having mixed functionality. The precursor includes a curable functional group and an isocyanate group capable of reacting with an alcohol group of the polyol. The precursor reacts with the alcohol group of the polyol to form a urethane linkage and to add a covalently bonded curable functional group to the polyol. The oligomers can be included in coating compositions for optical fiber and lead to coatings having improved tear strength.

摘要:The preparation of monodispersed TiO 2 nanocrystals with nanocrystal size between 1-30 nm is described herein. These TiO 2 nanocrystals are used to prepare dispersions into solvents, formulation into monomers, oligomers, and polymers, and nanocomposites from the resulting formulations. Dispersions of nanocrystals can be formed in various solvents at high loading, high transmittance, and low viscosity. Formulations incorporating these nanocrystals and a matrix material are highly stable, where the resulting nanocomposites have high refractive index and are optically transparent in the visible wavelengths, with very little or no scattering.

标题:Use of functionalized and non-functionalized ecms, ecm fragments, peptides and bioactive components to create cell adhesive 3d printed objects

摘要:Embodiments of this disclosure relate to bioinks and bioink compositions. These bioinks may be 3D printed into a hydrogel. The printed hydrogel may support primary cell and induced pluripotent stem cell attachment, proliferation, and spreading. Compounds in the bioink may be modified to incorporate chemical functionality, such as by chemical synthesis means. Incorporating chemical functionality may allow the incorporation of modified material as a component in the bioink. The modifications may allow chemical conjugation of a desired component. The desired component may maintain its cell interactive feature to aid in cell attachment and proliferation. Such incorporation may allow modulation of the bioprinted object's mechanical properties without interfering with cell adhesion.
