▎ 摘　　要

NOVELTY - The method involves bonding the fluorescent acceptor group and the fluorescent donor group at the two ends of the high molecular chain, and then grafting one end of the high molecular chain on the surface of the nano particle. The nano-particles grafted with high molecular chain obtained in the solvent is dispersed, and shear is applied, and the excitation light is emitted to the dispersion liquid by the fluorescence spectrometer. The fluorescence emission spectrum is received by the receiver. The change trend of chain end distance of the macromolecule chain which is grafted on the surface of the nanometer particle with the change of the cutting speed is changed by change of the ratio of the fluorescence acceptor group and the characteristic peak of the fluorescence donor group. USE - Method for detecting macromolecule chain conformation grafted on surface in flow field in real time by using non-radiation energy transfer. ADVANTAGE - The method for real-time detecting macromolecule chain conformation grafted on the surface of nanoparticles in flow field by using non-radiation-energy transfer technology obtains different molecular weight different graft rate of nanoparticle surface macromolecule chain conformation along with the shear rate change of the general rule, so as to maintain a specific conformation in the specific shear rate of the high molecular chain of the surface of the nano-particle, determines the chain length of the macromolecule grafted on the surface of the target nano-particle according to the obtained rule, graft density and so on parameter, which provides guarantee for realizing accurate nano manufacturing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for predicting relationship between conformation of polymer chain grafted on surface of the nano-particle and the shearing rate in the flow field. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of the variation of the fluorescence signal on the surface of the particle with the shear rate.
