Carboxylic acid functionalized multi-walled carbon nanotube-adsorption onto poly(methyl methacrylate) microspheres.
We prepared multi-walled carbon nanotube (MWNT) coated polymeric microspheres i.e., carboxylic acid functionalized MWNT (c-MWNT) adsorbed onto poly(methyl methacrylate) (PMMA) microspheres. Initially, the MWNT was functionalized with carboxylic acid functional group and PMMA microspheres were synthesized via a dispersion polymerization method separately. The c-MWNT/PMMA microspheres were then fabricated by blending technique i.e., simple mixing of c-MWNT and PMMA microspheres dispersed solutions under ultrasonication. Surface morphologies of the c-MWNT-adsorbed PMMA microspheres were observed using scanning electron microscopy (SEM). In addition, c-MWNT/PMMA microsphere suspension dispersed in silicone oil showed typical electrorheological characteristics of fibril structure under an applied electric field.
