Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
The invention provides a preparation method of hydrophobic cotton, which is generally completed in two steps, wherein in the first step, a GA-Cu (II) complex modified layer is formed on cotton fabric through the quick coordination assembly reaction of GA (gallic acid) and Cu (II) (divalent copper ions), the reaction is very quick, and the color of the cotton fabric is changed from white to light yellow; in the second step, the GA-Cu (ii) complex modification layer is reacted with an amine, sulfur or alcohol containing molecule to produce a long chain hydrocarbon species by michael addition or schiff base reaction under basic conditions to produce a hydrophobic surface.
The method comprises the following steps of preparing a GA-Cu (II) complex modified layer, preparing a Schiff base reaction product, and reacting the GA-Cu (II) complex modified layer with a molecular containing amine, sulfur or alcohol to generate long-chain hydrocarbon substances, wherein the GA-Cu (II) complex modified layer formed by GA and Cu (II) is relatively stable and has relatively high reaction speed, and the cotton fabric has certain hydrophobic capacity. The more specific preparation method of the hydrophobic cotton comprises the following steps:
FIG. 1 is a flow chart of the process for making hydrophobic cotton according to the present invention. In the example shown in fig. 1, the hydrophobic cotton preparation method comprises: step S1, immersing the cotton fabric in the copper ion salt solution and the gallic acid solution in sequence to form a GA-Cu (II) complex modified layer on the surface of the cotton fabric; and step S2, reacting the GA-Cu (II) complex modified layer with amine, sulfur or alcohol containing molecules to generate long chain hydrocarbon substances by Michael addition or Schiff base reaction under alkaline conditions to obtain hydrophobic property. The copper ion salt solution comprises a copper sulfate solution or a copper chloride solution. The description will be made below with reference to a copper sulfate solution.
In a further embodiment, step S1 specifically includes immersing the cotton fabric in a copper sulfate solution having a concentration of 2.5mg/ml to 15mg/ml, and incubating at 70 ℃ to 100 ℃ for 30 min. The purpose of the step is to make the divalent copper ions uniformly adsorbed on the surface of the cotton fabric; the cotton fabric can be diluted by deionized water to remove redundant divalent copper ions, and ultrasonic oscillation can be assisted to ensure a better removal effect.
Further, the step S1 specifically includes immersing the cotton fabric taken out of the copper sulfate solution in a gallic acid solution with a concentration of 2mg/ml to 14mg/ml, so that a GA-Cu (ii) complex modified layer is formed on the surface of the cotton fabric. The cotton fabric has certain hydrophobic property, and the GA-Cu (II) complex structure is stable, so that the hydrophobic cotton prepared by the method has good durability.
In the embodiment of step S1, the present invention further provides a preferred embodiment, which includes: immersing the cotton fabric in a copper sulfate solution with the concentration of 10mg/ml, and preserving the heat for 30min at 80 ℃; then, the cotton fabric taken out of the copper sulfate solution is immersed in a gallic acid solution with the concentration of 12.8mg/ml, so that a GA-Cu (II) complex modified layer is formed on the surface of the cotton fabric. The preferred embodiments are presented with the objective of having hydrophobic properties as a first priority, and other combinations of preferred embodiments may be created with other objectives such as cost, etc. as a priority or consideration, and the invention is not limited in this regard. Various combinations are listed below in table 1 to illustrate the derivation of the preferred embodiment.
TABLE 1 Effect of CuSO4 concentration on the hydrophobic Properties of modified Cotton fabrics
As shown in table 1, when the concentration of the gallic acid solution was constant (specifically, 12.8mg/ml), the contact angle of the cotton fabric prepared by the step S1 with deionized water increased and then decreased as the concentration of the copper sulfate solution increased, and had the largest contact angle at the concentration of the copper sulfate solution of 10 mg/ml. As can be seen from Table 1, in another embodiment for cost savings, a copper sulfate solution concentration of 7.5mg/ml may be used. Of course, Table 1 is only made at a gallic acid solution concentration of 12.8mg/ml, and other preferred examples obtained by the same method using other gallic acid solutions are also within the protection of the present invention, and the comparison of the present invention is not limited.
Based on the above step S1 embodiment, in the specific embodiment of step S2, step S2 specifically includes immersing the cotton fabric with the GA-Cu (II) complex modified layer in an ethanol aqueous solution of octadecylamine with the concentration of 2mg/ml to 10mg/ml, and keeping the temperature at room temperature for 1h to 8h, so that the GA-Cu (II) complex modified layer of the cotton fabric reacts with molecules containing amine and alcohol to generate long-chain hydrocarbon substances to obtain hydrophobic property. The principle is that after the gallic acid and bivalent copper ion generate GA-Cu (II) complex, the free carboxyl of the gallic acid can also react with molecules containing amine, sulfur or alcohol to generate long-chain hydrocarbon substances, so that the surface energy of the hydrophobic cotton is further reduced, and the hydrophobic performance of the hydrophobic cotton is increased.
In the embodiment of step S2, the present invention also provides a preferred embodiment, which comprises immersing the cotton fabric with the GA-Cu (ii) complex modified layer in an aqueous solution of octadecyl amine alcohol with a concentration of 8mg/ml, and incubating at room temperature for 4h, so that the GA-Cu (ii) complex modified layer of the cotton fabric reacts with molecules containing amine and alcohol to generate long-chain hydrocarbon substances to obtain hydrophobic properties. The preferred embodiments are presented with the objective of providing hydrophobic properties, and other combinations of preferred embodiments may be created with the objective of priority or consideration of other objectives, such as manufacturing costs, and the invention is not limited in this regard. Various combinations are listed below in table 2 to illustrate the derivation of the preferred embodiment.
TABLE 2 Effect of octadecylamine concentration on the hydrophobic Properties of modified Cotton fabrics
In table 2, for simpler characterization of the concentration of the octadecylamine ethanol solution, the Octadecylamine (ODA) concentration was substituted. Wherein, when the concentration (12.8mg/ml) of the gallic acid solution and the concentration (10mg/ml) of the copper sulfate solution are unchanged, the contact angle of the cotton fabric prepared by the step S2 and the deionized water is increased and then decreased along with the increase of the concentration of the Octadecylamine (ODA) and the increase of the reaction time, and when the concentration of the Octadecylamine (ODA) is 8mg/ml and the reaction time is 4h, the contact angle of the prepared cotton fabric is the largest, and the hydrophobic property is the best. Of course, Table 2 is only made for the case where the concentration of gallic acid solution is 12.8mg/ml and the concentration of copper sulfate solution is 10mg/ml, and other preferred embodiments obtained by using gallic acid solution with other concentrations are also within the protection of the present invention, and the present invention is not limited thereto.
In a more complete example, the procedure for preparing hydrophobic cotton in the experiments of the present invention is as follows:
a piece of 5cm by 5cm pure cotton fabric was placed in a 500ml beaker, washed clean with deionized water, and then laid flat in the beaker and dried in a vacuum oven at 80 ℃. After drying, putting the washed fabric into a 500ml beaker, adding 20ml of copper sulfate solution with a certain concentration into the beaker, flatly spreading the fabric as much as possible so as to completely soak the fabric, adding 60ml of deionized water after soaking for 30min, ultrasonically shaking the fabric at room temperature until the fabric is fully diluted, adding 20ml of 12.8mg/ml gallic acid solution, ultrasonically shaking the fabric for 30min again, taking out the cotton fabric, washing the cotton fabric with a large amount of deionized water, and drying the cotton fabric in a vacuum oven at 60 ℃ to obtain the gallic acid-metal copper ion complex modified cotton fabric.
And (3) putting the dried modified cotton fabric into 80ml of octadecylamine ethanol aqueous solution with a certain concentration, and reacting for 4 hours at room temperature. And taking out the fabric, washing the fabric with ethanol and a large amount of deionized water, and drying the fabric in a vacuum oven at 60 ℃ to obtain the hydrophobic modified cotton fabric.
Wherein, the comparison graph of the infrared spectrum of the cotton fabric with hydrophobic property obtained primarily in the step S1 and the hydrophobic cotton prepared in the step S2 is shown as the following graph:
FIG. 2 is an infrared spectrogram of cotton fabric at each preparation stage of the present invention. As shown in figure 2, after the gallic acid-copper ion complex-octadecylamine copolymerization modification, the infrared spectrum of the cotton fabric is compared with that before the modification, and the stretching vibration absorption peak of hydroxyl at 3341cm < -1 > is weakened, because part of phenolic hydroxyl is consumed by octadecylamine reaction, so that the hydrophilic hydroxyl on the surface of the cotton fabric is greatly reduced, the surface energy is reduced, and the hydrophobicity of the material is enhanced. In FIG. 2, 2920cm-1 shows an asymmetric stretching vibration absorption peak of-CH 2-in octadecylamine, and 2856cm-1 shows a symmetric stretching vibration absorption peak of-CH 2-in octadecylamine. 1340cm-1 is the-NH-in-plane bending vibration peak of a primary or secondary amine. 1160cm-1, 1110cm-1, 1057cm-1 and 980cm-1 are the stretching vibration absorption peak of-C-O-C-, and 500cm-1 is the characteristic peak of cotton fiber. As can be seen from fig. 2, the surface energy of the hydrophobic cotton prepared through step S2 is significantly reduced compared to the hydrophobic cotton primarily obtained through step S1 and the original cotton fabric, so that the hydrophobic cotton prepared by the method of the present invention has better hydrophobicity, and in addition, the lower surface energy is also stronger in the stain resistance of the hydrophobic cotton prepared by the present invention. FIG. 3 is a comparative graph of the hydrophobic capacity of the hydrophobic cotton of the present invention. As shown in fig. 3, substances such as ink, milk or water are not easily soaked on the hydrophobic cotton fabric of the invention.
In addition, the invention also carries out an oil-water separation experiment of the hydrophobic cotton, and particularly, the experiment is shown in figures 4 to 7. Fig. 4 is a state diagram before oil-water separation. Wherein the water is dyed blue with a water soluble pigment (such as copper sulfate) for convenient discrimination between oil and water. FIG. 5 is a diagram showing a state after oil-water separation. FIG. 6 is a state diagram of the hydrophobic cotton of the present invention before oil-water separation. FIG. 7 is a diagram showing the state of the hydrophobic cotton of the present invention after oil-water separation. In fig. 7 water is blocked on the surface of the hydrophobic cotton fabric. And as can be seen from the results shown in fig. 5, the hydrophobic cotton of the present invention has a good oil-water separation effect.
The method comprises the steps of forming a GA-Cu (II) complex attachment layer by coordination assembly of Gallic Acid (GA) and copper sulfate (CuSO4) on the surface of cotton fabric, and then forming a hydrophobic modification layer on the surface of the cotton fabric by reaction of Octadecylamine (ODA) and carboxyl of the gallic acid. Water-oil separation research shows that the prepared hydrophobic cotton fabric has good separation capacity on oil-water mixtures such as vegetable oil/water, engine oil/water and the like, and the hydrophobic cotton fabric has excellent hydrophobic effect by reflecting from the side.
In addition, the invention also provides the hydrophobic cotton which is obtained by the preparation method described in each embodiment and has the beneficial effects of each hydrophobic cotton in each embodiment.
