Abstract

The invention discloses an organic polymer gelator and a preparation method and application thereof. The organic polymer gelator is excellent in gelation ability, takes an aromatic polymer as a main chain and is structurally modified to enable a side chain to contain benzenesulfonyl imidogen, so that the organic polymer gelator and polarity organic solvent molecules can efficiently form a hydrogen-bond cross-linked structure, and further, gel is formed. The organic polymer gelator has potential application value and development potentials in the fields of water treatment agents, oil spill at sea, biological tissue engineering, drug transportation, food, cosmetics, biological sensing and sensitive device preparation and the like.

Description

technical field [0001] The invention belongs to the field of polymer materials, and specifically relates to an organic polymer gel factor, its preparation method and application. The polymer gel factor has high-efficiency gel performance in polar organic solvents, so it is used in water treatment, nano It has good application prospects in the fields of material templates and drug carriers. Background technique [0002] Due to the special properties of both solid and liquid, organogels are widely used in biological tissue engineering, drug delivery, inorganic material templates, water treatment agents, cosmetics, food, marine oil spills, biosensing and sensitive device preparation, propellant performance optimization, etc. It has great application potential and has attracted more and more attention. [0003] According to the different molecular weights of gelling factors, organogelling factors can be divided into low molecular weight organic gelling factors and organic polym...
