Description
Technical Field
The invention belongs to the technical field of polymer preparation, and particularly relates to a Y-type fluorine-containing amphiphilic polymer and preparation and application thereof.
Background
Currently, surfactants are widely used in daily life, such as cosmetics, textiles, medicine, construction, and other fields, mainly because they are dissolved in liquids to significantly reduce the surface tension or interfacial tension of the solutions, which plays a vital role in improving the performance of the materials. Today, researchers have found that fluorinated materials tend to exhibit unique hydrophobic oleophobicity, chemical stability, thermal stability, etc., due to the small atomic radius, low polarizability, and high bond energy of fluorine atoms, fluorinated surfactants have emerged. It was found that the minimum surface tension value of fluorosurfactant at the critical micelle concentration is significantly lower than for hydrocarbon surfactant. Along with the development of industrial technology, the large-scale production and application of fluorine-containing surfactants such as perfluorooctanoic acid (PFOA), perfluorooctyl sulfonic acid (PFOS) and the like are realized, while enjoying the welfare, people gradually find that the long fluorocarbon chain compound is easy to biologically accumulate and difficult to degrade in nature due to the stable property (J.fluoro chem.2009,130, 1192-1199), which not only causes great threat to human beings, but also endangers the natural environment for the human beings to live. Therefore, it is important to design a fluorosurfactant with excellent surface activity and no bioaccumulation, mainly by developing a short fluorocarbon chain surfactant or inserting a heteroatom such as N, O in a long fluorocarbon chain to make it easy to degrade.
In recent years, various types of surfactants, such as gemini surfactants, bola surfactants (Colloids surf. B Biointerfaces 2005,46,78), multi-chain surfactants (Langmuir 2015,31,10664) and the like, are designed and developed according to actual demands, and the unique structures of the molecules improve the surface activity of the molecules, so that the molecular surfactants have important application values in the fields of oilfield exploitation, emulsion polymerization, membrane protein treatment and the like. In 2019, zhou and colleagues used polyethylene glycol (PEG) and isophorone diisocyanate (IPDI) as raw materials, and a series of nonionic urethane fluorinated surfactants (J.mol. Liq.2019,296, 111851) were rapidly synthesized by a one-pot method. The two short fluoroalkyl chains are connected to one PEG molecule through two IPDI spacers, so that the surface tension of water can be reduced to 17.8-28.7mN/m, and the mode of introducing polyurethane into the molecular structure so as to connect the two fluoroalkyl short chains opens up a new green feasible way for preparing novel fluorine-containing surfactant. Ameduri et al prepared PVDF (polyvinylidene fluoride) emulsion (chem. Commun.2018,54,11399) using the degradable fluorinated surfactant 3-hydroxy-2- (trifluoromethyl) propionic acid (MAF-OH) as an emulsifier. The average particle size of the prepared PVDF latex particles decreases with increasing concentration of MAF-OH, and when MAF-OH is 2.0wt.%, the obtained PVDF latex particles are perfectly spherical, and the particle size is about 100nm.
Recently, the addition reaction between perfluoroalkyl iodides and α, ω -nonconjugated dienes has attracted interest to researchers because fluorinated segments can be simply and efficiently introduced into the molecular structure by this method. The addition reaction based on the interaction of halogen bond (XB) provides a green and efficient strategy for preparing fluorine-containing compounds. Among them, various types of amines, phosphines, halide salts and the like can be used as catalysts to activate the carbon-iodine bond of perfluoroalkyl iodides under the induction of visible light, promoting the addition reaction with alpha, omega-nonconjugated dienes. The above work opens the possibility of proposing an optimized synthesis method to obtain novel fluorosurfactants.

Example 2: surface activity research of Y-type fluorine-containing amphiphilic polymer
The present invention performed a static surface tension test on a series of Y-type fluorine-containing amphiphilic polymers obtained, FIG. 5 is F containing-CHI-bonds m EG n F m -I amphiphilic compound, FIG. 6 is F obtained by reductive iodination thereof m EG n F m . The static surface tension test data shows that the static surface tension value rapidly decreases along with the increase of the concentration and then becomes stable, and the surfactant molecules saturate at the gas-liquid interface and start to spontaneously form aggregates in the aqueous solution, and the turning point of the curve corresponds to the critical micelle concentration. The critical micelle concentration and the corresponding minimum surface tension data are summarized in table 1.
TABLE 1F at 25℃ m EG n F m (n=8, 13; m=4, 6) surface properties in aqueous solution
The CMC of the synthesized fluorine-containing surfactant molecules in the aqueous solution is very low, can reach 0.69mmol/L, is far lower than CMC (10 mmol/L) of PFOA, and can reach 18.5mN/m of the lowest surface tension value. This is mainly due to the molecules we synthesizeThe water molecules are more easily and tightly arranged on the surface of the water molecules in a Y shape, and occupy a certain area at the gas-liquid interface, so that the water molecules have smaller critical micelle concentration. From F 4 EG 8 F 4 -I and F 6 EG 8 F 6 As can be seen from the comparison of the data of the formula I, the adsorption quantity gamma of the surfactant at the gas-liquid interface is increased along with the increase of the length of the fluorine chain max Increased average minimum area a per surfactant molecule min And (3) reducing. These phenomena may be due to the fact that lengthening the fluorocarbon chain (increasing the size of the hydrophobic tail) may increase the steric effect, the interaction between F-F is enhanced, leading to an increase in the number of aggregates, the smaller the minimum surface tension value. And F (F) 6 EG 13 F 6 -I and F 6 EG 8 F 6 Comparison of I shows that as the hydrophilic chain length increases, the adsorption of surfactant at the gas-liquid interface decreases, correspondingly the average minimum area A per surfactant molecule min The increase, i.e., the more loosely arranged surfactant molecules at the gas-liquid interface. After reduction of the carbon-iodine bond to a hydrocarbon bond, the hydrophobicity is stronger. With increasing concentration, the minimum surface tension of the surfactant is obviously reduced, compared with the adsorption amount of the surfactant at the gas-liquid interface is reduced when iodine is not extracted, and accordingly the average minimum area A of each surfactant molecule is correspondingly reduced min And (3) increasing.
Example 3: influence of pH and electrolyte on surface tension
For surfactants, not only good surface activity but also stable performance under extreme conditions is important, and therefore, it is essential to conduct salt tolerance and pH tolerance tests on fluorosurfactants. In the research of the invention, we first explore the stability of the surface properties of the synthesized Y-type fluorine-containing amphiphilic polymer in the presence of electrolyte. As shown in fig. 7a, the surface tension does not substantially change as the concentration of sodium chloride in the aqueous solution increases. Subsequently, we have formulated a series of aqueous surfactant solutions of different pH (FIG. 7 b), which shows that pH changes at room temperature have little effect on surface activity, and that pH changes may have an effect on structure and properties if "ester groups" are present in the Y-type fluorine-containing amphiphilic polymer in a high temperature environment. In summary, the series of compounds has excellent salt and pH resistance at room temperature.
Example 4: wetting and spreading Property study
For some low energy solid surfaces, researchers often add surfactants to the solution to adjust the solid-liquid interface so that the solution exhibits good wetting and spreading properties on the solid surface, and contact angles are considered as criteria for evaluating such properties, with smaller contact angle values indicating better wetting properties. In this invention, the inventors formulated a range of aqueous surfactant solutions at concentrations of 0.1wt.% and 0.01wt.%, investigated their wettability on parafilm or polytetrafluoroethylene film and compared to the wettability of perfluorooctanoic acid. As shown in FIG. 8 and FIG. 9, the prepared aqueous solution of the fluorine-containing surfactant can show excellent wettability on the parafilm, and the contact angle is smaller when the concentration is higher, namely the better the wettability is, the contact angle can reach about 55.7 DEG at the lowest, and the contact angle is obviously lower than the contact angle (-83.1 DEG) of PFOA. Furthermore, the inventors have chosen polytetrafluoroethylene as the substrate (see fig. 10), and still see that the aqueous fluorosurfactant solutions of this series have better wettability (39.5 °) than perfluorooctanoic acid (64.5 °) at the same concentration. It follows that the series of surfactants can still exhibit excellent wetting properties at very low concentrations, meaning that the series of fluorosurfactants may have potential application in the textile, paper industry.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations and modifications of the present invention will be apparent to those of ordinary skill in the art in light of the foregoing description. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
