Description
Technical Field
The invention relates to the technical field of polymer synthesis, in particular to a macromolecular surface modifier and a synthesis method thereof.
Background
At present, as the requirements on the hydrophobic, oleophobic, hydrophilic and lipophilic properties of the surface of the material are increased, for example, blood product packaging materials or flow guide materials, materials which are in contact with body fluid and have the effects of resisting bacteria and infection, materials which are in contact with the body fluid and need to reduce the surface energy, materials which can block toxic substances such as organic solvents, aldehyde ketones and the like, materials which can increase the liquid permeability, materials which can increase the oil absorption property and the like; these materials are used in particular in medical garments, protective clothing, thermoplastic films, thermoplastic fibers, face masks, laboratory clothing, blood permeable membranes, virus filtration membranes, gas exchange membranes, etc. However, most matrix materials do not have specific surface hydrophobic, oleophobic, hydrophilic and oleophilic properties, and therefore, a macromolecular surface modifier needs to be added for modification.
The macromolecular surface modifier is a polymer with the molecular weight of more than 1000, and compared with the micromolecular modifier, the macromolecular surface modifier has the advantages of multiple structures, controllable molecular weight, various functional groups, functional diversity and the like. In recent years, due to the potential industrial and commercial utility of macromolecular surface modifiers, the development of macromolecular surface modifiers of different types and structures has been pursued and extensively studied by researchers as an industrially important raw material.
Common polymerization modes of the conventional macromolecular surface modifier include ring-opening polymerization, Group Transfer Polymerization (GTP), Atom Transfer Radical Polymerization (ATRP) and reversible addition fragmentation-chain transfer polymerization (RAFT). Wherein, the atom transfer radical polymerization can effectively control the reaction process and design the required molecular structure and molecular weight. The ATRP reaction is suitable for various monomers, has mild reaction conditions, and is convenient to operate and the like. In practical application, the molecules can be designed, and substances with different hydrophilicity/hydrophobicity, polarity/non-polarity and the like can be combined together to adapt to different environments. At the same time, the copolymerization or grafting of macromolecules is carried out to achieve the purpose of molecular design, so that the product has different properties for different substances, namely, the interfacial activity of reactants is changed, and certain substances with poor solubility can be better dissolved with the reactants.
In the known prior art, invention CN103131079B discloses a microporous membrane and a battery separator containing the same. The microporous membrane takes polyolefin as a main raw material, and macromolecular surface modifiers are dispersed in the microporous membrane; one end of the macromolecular surface modifier is provided with a polyolefin chain segment which is hydrophilic to a matrix, and the other end is provided with a polyester or polyether block or graft chain segment which is electrophilic electrolyte. The macromolecular surface modifier is mainly polyolefin-polyester or polyether triblock copolymer, but the structure of the macromolecular surface modifier is different from that of the macromolecular surface modifier containing a hydroxyl chain segment, an isocyanate chain segment and a surface active group, and the application field of the macromolecular surface modifier is different.
The invention CN1970649B discloses a macromolecular surface modifier for modifying ceramic nanometer surfaces, which is an oligomer with the molecular weight of 3000-9000 and is obtained by the free radical initiated copolymerization of monomers such as (methyl) acrylic esters, vinyl siloxane and (methyl) acrylic acid, maleic anhydride, styrene, vinyl acetate, acrylonitrile and the like in an organic solvent. The macromolecular surface modifier is also different from the molecular structure related to the invention, the invention is free radical initiated copolymerization in the synthesis method, and the invention is functional group polymerization in Atom Transfer Radical Polymerization (ATRP) and has different application fields.
