1 The number in the code represents the concentration of the spinning solution; F1: the sample was in film form in the first stage; F2: the sample was in film form in the second stage; E1: the sample was in ethanol coagulation in the third stage; E2: the sample was in ethanol coagulation in the fourth stage.
