“…2 Network polymers have been increasingly studied for their tunable functionalities, controllable pore geometries and wide range of applications. [35][36][37][38][39][40][41][42] Although conventional polymers and their derivatives, such as poly(acrylic acid), 43 cellulose, 44 carbonaceous materials, 45,46 poly(orthocarbonate), 47 microporous polymers, 48,49 poly(lactic acid), 50 polyaniline, [51][52][53] were used as superabsorbents to remove oils, metal ions, toxic dyes and organic solvents from water, some of these materials were synthesized by using transition metal catalysts and sometimes at high temperatures. 54 Therefore, new, low cost and effective adsorbents are always needed.…”
