一般描述
N,N-Dimethylacetamide (DMAc) is widely used to compose solvent mixtures for cellulose. Static and dynamic light scattering studies of cellulose dissolved in varying concentrations of DMAc/LiCl mixtures have been reported.
应用
N,N-Dimethylacetamide have been used as solvent in the preparation of nanocomposite materials, comprising of cellulose and hydroxyapatite, using microwave-assisted method. It has also been used as a solvent for poly(ether imides), which can be used to coat magnesium alloys, in order to prevent corrosion.

An amphiphilic triblock co-polymer of poly(vinyl pyrrolidone)-b-poly(methyl methacrylate)-b-poly(vinyl pyrrolidone) (PVP-b-PMMA-b-PVP) was synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization. The block co-polymer can be directly blended with polyethersulfone (PES) using dimethylacetamide (DMAC) as the solvent to prepare flat sheet and

Hierarchical self-assembly offers elegant and energy-efficient bottom-up strategies for the structuring of complex materials. For block copolymers, the last decade witnessed great progress in diversifying the structural complexity of solution-based assemblies into multicompartment micelles. However, a general understanding of what
