An acid labile branched PDMAEMA/acetal copolymer with amino group was synthesized by the DE-ATRP and followed by Michael addition. The degradation of the polymer was strongly pH-dependent. High nucleic acid transfection efficiency with low cytotoxicity was observed compared to its non-degradable copolymer counterpart.
A well-defined poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA-b-C60) was synthesized using the atom transfer radical polymerization (ATRP) technique and betainized with 1,3-sulfobetaine to yield a Bet-PDMAEMA-b-C60. The solution properties were then studied by light transmittance, viscometric, 1H NMR laser light scattering, and transmission electron macroscopic techniques. It was found that...
Background and Aim: graphene is a two-dimensional nanostructure consist of a single layer of SP2 carbon atoms that arranged by covalent bonds in a hexagonal bee web. The reinforcement by GO is due to functional groups that lead to strong interaction, dispersion and stress distribution. Due to lower mechanical properties and strength of PEMA than PMMA, we evaluate effect of GO on mechanical prop...
