Attenuated total Interpenetrating polymer network hydrogel reﬂection-Fourier transform infrared spectroscopy (ATR-FTIR) and thermogravimetric analysis (TGA) conﬁrmed pH-sensitivity the formation hybrid network of NFC and PDMAEMA. The IPN hydrogels possess uniform pore structure and Thermosensitivity 2 −1 high porosity (> 97%). The speciﬁc surface area and compressive strength were higher than 82 m g and Adsorption 1.26 kPa,
