Highly boron-selective adsorbent by radiation induced grafting of N-vinylformamide on polyethylene/polypropylene sheet followed by hydrolysis and glycidol treatment

“Functional upcycling” of polymer waste towards the design of new materials

“…Herein, we overview these examples to inspire scientists for implementing these strategies for upcycling of waste PE to produce new functional materials. Based on commercial PE materials, several functionalisation approaches have been applied, highlighting the adsorption applications of metal ions such as Au 3+ , Cu 2+ (Table 2(3)), 176,193 (Table 2(4)), 181 boron (Table 2(3)), 194 iodine (Table 2(3)), 158 CO 2 (Table 2(3)), 180 and organic pollutants (pesticides and antibiotics) (Table 2(5)). 149,199,202,203 The most common substrates include PE-PP nonwoven fibers or fabrics and films.…”
