A random terpolymer of N-(2-hydroxypropyl) methacrylamide, carboxybetaine methacrylamide and sulfobetaine methacrylamide, and a polymer brush and to a functionalized polymer brush containing this terpolymer are disclosed. The random terpolymer increases the resistance of the substrate surface to non-specific adsorption of substances from biological media and/or to non-specific interaction with biological media components, and is suitable for use in the form of a polymer brush, for example in sensors or membranes.

Disclosed are co-polymers which are produced from reactive monomer mixtures and which have both high refractive index and a high Abbe number. These materials are well suited for use as implantable ophthalmic devices and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.

The present invention discloses a film for a medicine packaging and a method of preparing the same. The film for the medicine packaging includes a polymer film layer, a graphene composite layer and a light-curable adhesive, wherein the polymer film layer is bonded with a graphene composite layer by a light-curable adhesive, the graphene composite layer includes multiple graphene layers bonded by the light-curable adhesive; and the light-curable adhesive includes a hyperbranched cationic mussel-imitated polymer including a multi-hydroxylbenzoylbenzamide ene amide monomer, a cationic monomer and a photo-responsive monomer. The present invention provides strong adhesion with reduced adhesive layer, allowing greatly increasing the number of the graphene layers in the graphene composite layer without obvious increase in the total thickness and mass. This can meet the requirements of the medicine packaging material, as it obviously lowers the film's permeation to water vapor and oxygen and significantly enhances the tensile strength.

This present invention relates to a drug carrier comprising a polymer of γ-glutamyl transpeptidase catalyzing hydrolysis-induced charge reversal, and a method for preparing the same. It can have a long circulation time in the blood, and can realize a charge reversal from negatively charged or the neutral to positively charged around the tumor blood vessel region, so that the positively charged polymer effectively penetrates deep into the tumor tissue, fast entering into the tumor cells, and greatly improves the therapeutic effect of the drug on the tumor. This overcomes the problems of slow diffusion of traditional polymer drug carriers in tumors and weak interaction with tumor cells, and has great significance in the field of anticancer treatment in the medical field.
