Preparation and properties of a photocrosslinked MCl_n-doped PDMA-g-PSMA hydrogel

Abstract

Na+ or Mg2+ doping can improve the elongation at break, equilibrium swelling ratio and self-healing efficiency of PDMA-g-PSMA hydrogels. Among them, MgCl2-doped PDMA-g-PSMA has better shape stability, lower friction coefficient and lower wear loss.

Mechanical, robust and conductive eco-friendly self-assembling hydrogel: a novel material for electromagnetic shielding

“…[1][2][3][4][5][6][7] Radiofrequency and broadband electromagnetic waves have gradually gained popularity, especially with the development of portable devices such as Bluetooth, tablet computers and electronic monitoring devices. [8][9][10][11][12][13][14][15] However, while these devices bring us the convenience of life, they are accompanied by the issue of electromagnetic wave pollution. 11,16,17 The increasingly serious issue of extremely harmful electromagnetic radiation pollution, caused by the misuse of various electronic products and improper recycling behavior of equipment waste, poses irreparable harm and endangers the environment, humans, and other species.…”
