pH responsive nanoplates from bulk self-assembly of UV-crosslinkable poly(tert-butyl acrylate)-block-poly(2-cinnamoyloxyethyl methacrylate)

Original Paper


We report the dispersed nanoplates prepared from bulk self-assembly of diblock copolymer poly(tert-butyl acrylate)-block-poly(2-cinnamoyloxyethyl methacrylate) (PtBA-b-PCEMA) with PCEMA as a UV-crosslinkable segment and PtBA as a hydrolysable segment. PtBA-b-P(HEMA-TMS) was synthesized through a two step ATRP and functionalized to PtBA-b-PCEMA. The diblock copolymer with 55.7 % weight ratio of PCEMA bulk was assembled into lamellar morphology and characterized by small-angle X-ray scattering (SAXS). After UV-crosslinking, the dispersed nanoplates were prepared by dispersing the crosslinked bulk self-assembly in a good solvent of the PtBA segment and characterized by transmission electron microscopy (TEM). The dispersed nanoplates have crosslinked PCEMA as the cores and the solubilized PtBA as the coronas. After hydrolysis of the PtBA segment into poly(acrylic acid) (PAA), the crosslinked nanoobjects could be dispersed in water and showed reversible pH-responsibility.
