Background: Polyacrylamide hydrogel plays an important role in many areas. There also has been growing interest in polyacrylamide hydrogel modification by polymerizing and crosslinking methods, introducing different groups to obtain various functions. Purpose: The aim is to propose a novel one-step irradiation-induced polymerizing and crosslinking method to prepare polyacrylamide (PAAm) composite hydrogel with polystyrene (PS) nanospheres. Methods: The chemical structures of PAAm composite hydrogel with PS nanospheres were measured by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron Spectroscopy (XPS). Scanning electron microscopy (SEM) was used to observe the surface structure of the composite hydrogel. Adsorption ability of hydrogel was evaluated via water and ethanol. Results: It is found that the PS nanospheres were introduced successfully to PAAm hydrogel, which were of superior absorption in deionized water and normal saline water. Conclusion: This novel one-step irradiation-induced method is proved to be simple and feasible to prepare PAAm composite hydrogel with PS nanospheres at room temperature.
