In this paper

we introduced a new opened comprehensive experiment about polymer hydrogel.To improve students’ scientific research ability

six different experiments connected with each other about polymer hydrogel were designed combining with fiber materials

hydrogel and organic/inorganic hybrid materials. Experiments were rich and colorful as well as simple and easy to operate. Students are free to select the different experiments

design experimental procedure and operate. In this way the lack of "autonomy"and "design" in the comprehensive experiment was solved and giving fully the students’own initiative. Experimental results showed that the experimental design was reasonable and can fully stimulate the students’ interest and enthusiasm as well as effectively cultivate college students’abilities of discovery

understanding and solve problems independently. It is worthy of further promotion.
