[0012] 1. Material preparation
[0013] (1) Preparation of reagents
[0014] The main reagents are: palmitic acid (hexadecanoic acid), absolute ethanol (CH 3 CH 2 OH), sodium hydroxide (NaOH), glacial acetic acid (CH 3 COOH), hexamethylenetetramine (C 6 h 12 N 4 ), zinc nitrate (Zn(NO 3 ) 2 ·6H 2 O), zinc acetate (Zn(CH 3 COO) 2 2H 2 O).
[0015] (2) Tested cotton fabric
[0016] Cotton plain weave, purchased locally.
[0017] (3) Experimental instruments and equipment
[0018] Constant temperature magnetic stirrer, oven, ultrasonic cleaning machine.
[0019] 2. The specific process of preparing materials is:
[0020] a. Prepare 0.05mol / L zinc acetate alcohol solution at 60~65℃, add 0.10~0.15mol / L sodium hydroxide alcohol solution drop by drop under stirring until a transparent zinc oxide colloid with Tyndall phenomenon is formed solution;
[0021] b. Soak the cleaned cotton fabric in the colloidal solution of zinc oxide obtained in step a for 2-5 minutes, th...
