Description

一般描述

N，N-二甲基乙酰胺（DMA）是一种非离子丙烯酸单体，可用于制备可溶胀的聚合物颗粒。

N,N-Dimethylacrylamide(DMAA) is a non-ionic polymer with high reactivity and low initiation temperature. The unique structure of DMMA can form a three-dimensional network with other hydrogels and enhance their water retention capacity. It is widely used in the preparation of hydrogels, polymeric flocculants, polymer coatings, and self-healing materials.

应用

DMA可用于合成光响应聚合物。它被用于通过均聚合在DMA侧链上
接枝聚硅氧烷而合成共聚物，或通过
接枝纤维素而形成纤维素聚合物 ，以及
用于甲基丙烯酸甲酯与DMA的共聚合或
DMA与苯乙烯和丁二烯的共聚合

N,N-Dimethylacrylamide(DMAA) can be used as a precursor to synthesize:

• A series of DMMA-based hydrogels for the removal of heavy metals and organic dyes from polluted water. These hydrogels are highly efficient in removing cationic dyes due to electrostatic interaction and hydrogen bonding in the DMMA backbone.
• Non-toxic luminescent carbon dot/poly(DMMA) nanocomposite via surface-initiated reversible addition-fragmentation chain transfer polymerization.
• Polymer coating for quartz crystal microbalance(QCM) sensor. The poly(DMMA) gel acts as a sensing material to adsorb Au(III) ions from HCl aqueous solution and it is inactive to most other metal ions and organic compounds.

特点和优势

• It is an appropriate precursor for copolymerization due to its low initiation temperature and high reactivity.
• Its unique structure forms a 3D network and improves the water retention capacity of hydrogels.
• It is highly soluble in water.
• It can easily bind to colloidal particles to enhance the bridging effect which plays a key role in flocculation.
