Can polyacrylamide-phytic acid-polydopamine (PAAM/PA/PDA) conducting porous hydrogel?

In this article, for the first time, the polyacrylamide-phytic acid-polydopamine (termed as PAAM/PA/PDA) conducting porous hydrogel has been synthesized and could been employed for rapid detection and effective removal of Cu 2+. 2. Experimental section 2.1. Materials and reagents

What is polyacrylamide-phytic acid-polydopamine conducting hydrogel?

The polyacrylamide-phytic acid-polydopamine conducting hydrogel was synthesized for the first time. The conducting hydrogel presents a great removal capacity toward copper (II) ions. in real samples. 1. Introduction

Can polyacrylamide-phytic acid-polydopamine hydrogels be used as reusable adsorbents?

Herein, we demonstrate that the three-dimensional porous polyacrylamide-phytic acid-polydopamine (termed as PAAM/PA/PDA) hydrogel can be served as reusable adsorbent with high efficiency for either anionic or cationic dyes.

Is the conducting porous PAAM/PA/PDA hydrogel a novel material for electrochemical sensor?

In summary, the conducting porous PAAM/PA/PDA hydrogel has been synthesized and applied as a novel material for fabricating electrochemical sensor since the PAAM/PA/PDA hydrogel has high surface-area-to-volume ratio, enhanced electrical conductivity and relative strong mechanical properties.

How to test the conductive capacity of PAAM/PA/PDA hydrogel?

In order to test the conductive capacity, the PAAM/PA/PDA hydrogel is firstly used to fabricate an electrochemical sensor for Cu 2+ detection. The fabrication process is shown in Scheme 1b. The PAAM/PA/PDA hydrogel can directly form on the surface of GA modified GCE when the mixture of monomers is dropped on electrode surface.

Does Cu 2+ interact with PAAM/PA/PDA hydrogels?

In the presence of Cu 2+, the peaks of C-O, C˭O and O-H are shifted from 285.3 to 286.2 eV, 288.2–288.3 eV and 531.9–532.2 eV (as shown in Fig. S13 ), respectively. The result indicates that the Cu 2+ has strong interaction with hydroxyl group and carboxyl groups of PAAM/PA/PDA hydrogel.
