Detailed Description
Example 1
The method of fixing a laundry detergent additive of this embodiment comprises:
1) preparing ZnO nanowires by direct physical evaporation method, wherein the diameter is controlled to be 10-50nm, and the length is 5-100 um; and simultaneously, the HF is utilized to carry out surface chemical etching treatment to manufacture defects so as to promote the interaction of the nanowires and the coupling agent.
The method for manufacturing the defect point by performing surface chemical etching treatment by using HF comprises the following steps:
11) dispersing ZnO nanowires into 0.5% amino acid aqueous solution, and soaking for 1-5 min, wherein the amino acid is histidine (pI ═ 7.59) or lysine (pI ═ 9.74) with pI greater than 7 or a composition of the histidine and the lysine; as ZnO in aqueous solution has negative charge due to the action of hydroxyl, amino acid has positive charge when pH is less than isoelectric point pI, and the amino acid is adsorbed on the surface of ZnO nanowire.
12) Taking out the soaked ZnO nanowire and drying;
13) etching the dried ZnO nanowire by using HF with the concentration of 0.1-1% to form a plurality of defect points;
14) and dispersing the etched ZnO nanowire in a sodium hydroxide solution with the pH value larger than the pI again for desorption.
2) Preparation of the additive
Adding 1-2 parts of monoalkoxy titanate coupling hydrophilic modifier into an aqueous solution dispersion system containing 1-2 parts of glycerol, 0.2-1 part of carboxymethyl cellulose, 1-2 parts of sodium polyacrylate and 3-5 parts of polyvinylpyrrolidone, stirring uniformly, and slowly adding 10-30 parts of ZnO nanowires to prepare the hydrophilic ZnO nanowire dispersion liquid.
