摘要:
The present invention relates to a labelled particle, i.e. a particle comprising a component and a tracer compound, a composition comprising said labelled particle, a method of manufacturing said labelled particle, a method of manufacturing said composition, and a method of determining the presence of said labelled particles on a substrate surface or in a volume of a fluid selected from the group consisting of a gas, a liquid, and a supercritical fluid.
摘要:
The present invention provides nanoparticles of which matrix is a thermosetting resin in which a hydrophobic fluorescent substance is accumulated, wherein the nanoparticles have luminance that is high enough to enable pathological diagnosis by using a fluorescence image of a biological substance such as a protein, a nucleic acid, or the like, labeled with the nanoparticles. In the fluorescent substance-accumulated nanoparticle according to the present invention, the thermosetting resin includes a structural unit formed from a raw material having a hydrophobic substituent, and the fluorescent substance is accumulated in the nanoparticles by at least a hydrophobic interaction, preferably additionally by a stacking interaction, occurring between the fluorescent substance and the hydrophobic substituent of the thermosetting resin.
摘要:
The present disclosure provides a curable composition containing a benzoxazine, reactive diluent and a soluble polyimide. The curable composition, upon curing, renders an article having well balanced thermal, chemical and mechanical properties and may be used in a variety of applications, such as in coatings, structural composites and encapsulating systems for electronic and electrical components.
摘要:
The present invention relates to a halogen-free flame retardant resin composition, according to parts by weight, the resin composition comprises:(A) a mixture of phenoxyphosphazene compound (A 1 ) and compound (A 2 ) having dihydrobenzoxazine ring: 45-90 parts by weight, and the weight ratio of the phenoxyphosphazene compound (A 1 ) and the compound(A 2 ) having dihydrobenzoxazine ring is between 1:25-1:2; (B) an epoxy resin with epoxy equivalent of 500 -2000: 10-45 parts by weight; (C) a phenolic resin: 10-25 parts by weight, and (D) an amine curing agent: 0.5-10 parts by weight. The prepreg, laminate, metal-clad laminate for printed circuit prepared using the halogen-free flame retardant resin composition, have the advantages of high glass transition temperature (Tg), high thermal resistance, low dielectric dissipation factor, low water absorption as well as low C.T.E.
摘要:
Disclosed are solutions of polyvinylidene fluoride (PVDF) or copolymers of 1,1-difluoroethene in a solvent containing N-formylmorpholine (NFM), N-acetylmorpholine (NAM) or mixtures thereof and an additional co-solvent selected from among alkylene carbonate, mono-, di- or polyalkylene glycol dialkyl ether or mixtures thereof.
摘要:
A curable resin composition containing a blend of multifunctional benzoxazines, and composite materials derived therefrom. The benzoxazine blend contains the combination of (A) a difunctional benzoxazine component and (B) a multifunctional benzoxazine component with functionality of greater than 2. Cured matrix resins and cured composite materials containing such benzoxazine blend exhibit a significant retardation in the rate of organic solvent uptake as compared to the same cured matrix resins and composite materials without component (B).
