[求助] 石高全老师文献中高导电PEDOT:PSS水凝胶制备

石高全老师文献中高导电PEDOT

SS水凝胶制备
Preparation of PEDOT：PSS Hydrogels:

A PEDOT：PSS suspension (10.5 mg mL−1, Clevios, PH1000) containing containing H2SO4 (0.1 mol L−1) was sealed in a glass vial or a glass capillary (inner diameter = 0.5 mm) or a mold with desired size and shape. This system was kept at 90 °C for 3 h. The hydrogel fiber was released from the glass capillary to water by blowing air through the capillary. The as-prepared hydrogel was purified by repeated washing with deionized water. For the preparation of hydrogel film, PEDOT：PSS suspension in H2SO4 (0.1 mol L−1) was blade cast on a glass plate and maintained under a steam bath with a temperature of 90 °C for 3 h.

文献中水凝胶的制备方面有疑惑，理解有两种方式。第一种：将10.5 mg mL−1的PEDOT：PSS溶液加入配好的0.1 mol L−1硫酸中，此中方法制备的水凝胶硫酸体积不确定，只能试。第二种：在10.5 mg mL−1的PEDOT：PSS溶液中加入硫酸，体系中硫酸的浓度为0.1 mol L−1。不知道他们制备水凝胶是哪一种？各位网友帮忙解答
