报道了一种溴化咪唑鎓丙烯酸酯的纳米乳胶共聚物（25 - 30 nm），其提供了单壁碳纳米管（SWCNT）的稳定水性分散体以及粘附到塑料上的导热和导电涂层。这种分散单壁碳纳米管的方法通过同时提供稳定和粘合剂功能而超越了以前的报道。所得的薄膜表现出10倍的各向异性的导热性和导电性，并出现界面声子散射问题。除了提供简单的抗静电层配方外，在成膜时组装的导电网络还提供了一种新的途径来为电沉积用塑料涂底漆。这些纳米胶乳的功效归因于在其他研究中显示的对石墨烯表面具有亲和力的咪唑鎓和溴化物组分。
A nanolatex copolymer (25−30 nm) of an imidalozium bromide acrylate is reported that provides stable waterborne dispersions of single-walled carbon nanotubes (SWCNT) and thermally and electrically conducting coatings that adhere to plastics. This approach to dispersing SWCNT leaps past previous reports by providing stabilization and binder functions simultaneously. Resulting films exhibit 10-fold anisotropy in both thermal and electrical conductivity and appear free of interfacial phonon scattering problems. The electrically conducting networks assembled upon film formation provide a new route to priming plastics for electrodeposition in addition to providing simple antistatic layer formulations. The efficacy of these nanolatexes is assigned to the imidazolium and bromide components shown in other studies to have an affinity for graphene surfaces.
