ABSTRACT
A hydrophilic polyelectrolyte ion channel grafted polymer film based on carboxyl nitrile butadiene rubber latex (XNBRL) was prepared to enhance electrical conductivity and durability. In this research, XNBR was grafted with sodium acrylate (PAAS-g-XNBR), and cetyltrimethylammonium bromide (CTAB) was used to adsorb the monomer around the XNBR particles to form a new negative charge layer. The prepared PAAS-g-XNBR membrane section formed a continuous polyelectrolyte distribution, which prevented the formation of pores. Because the polyelectrolyte is strongly bound to the substrate by grafting chemical bonds, the ionic antistatic properties of the prepared film are durable and washable. Furthermore, the mechanical properties and antistatic properties of the film are balanced by the appropriate monomer content, and the appropriate vulcanization temperature also controls the appropriate moisture and crosslinking degree of the film. The results show that at 50% humidity, the optimal latex film achieves excellent conductive and antistatic properties (107 Ω) and good tensile strength (4.19 MPa), which present good application prospects in the field of thick protective touchscreen gloves with adjustable color.
