Embodiment 1
[0016] Step 1: configuration mass concentration is 2% chitosan aqueous solution respectively (chitosan obtains through degradation, and its molecular weight is about 3000), mass concentration is 2% gum arabic aqueous solution, mass concentration is 2% terbinaline hydrochloride Fen cream aqueous solution;
[0017] Step 2: the chitosan aqueous solution, gum arabic aqueous solution and terbinafine hydrochloride aqueous solution of step 1 gained are mixed according to the ratio of core wall 2:1, wall material ratio (chitosan / gum arabic) 1:1, mix The sequence is to first mix the gum arabic aqueous solution and the terbinafine hydrochloride solution, then add the chitosan solution, place the beaker in a constant temperature water bath, and stir for 15 minutes at a temperature of 40°C and a stirring speed of 400r / min;
[0018] Step 3: Use sodium hydroxide with a molar concentration of 0.1mol / L to adjust the pH value of the mixed solution obtained in step 2 to 5 to cause complex coace...
