Abstract
Provided are non-linear stimuli-responsive block copolymers, methods for synthesizing the block copolymers, and coating compositions comprising the block copolymers. In an embodiment, a composition is provided that comprises a non-linear stimuli-responsive block copolymer comprising a polyethylene glycol (PEG) block and a poly((2-dimethylamino)ethyl methacrylate) (PDMAEMA) block, wherein the non-linear stimuli-responsive block copolymer comprises a core region and three or more branches extending away from the core region, wherein the three or more branches comprise a branch comprising the PEG block, a branch comprising the PDMAEMA block, a branch comprising both the PEG block and the PDMAEMA block, or a combination thereof.

A composition comprising a non-linear stimuli-responsive block copolymer comprising a polyethylene glycol (PEG) block and a poly((2-dimethylamino)ethyl methacrylate) (PDMAEMA) block, wherein the non-linear stimuli-responsive block copolymer comprises a core region and three or more branches extending away from the core region, wherein the three or more branches comprise a branch comprising the PEG block, a branch comprising the PDMAEMA block, a branch comprising both the PEG block and the PDMAEMA block, or a combination thereof, wherein the non-linear stimuli-responsive block copolymer has a star morphology wherein the core region comprises a central molecular moiety and the three or more branches extend radially away from the core region, and further wherein the central molecular moiety is a sorbitan moiety, a branched alkyl moiety, or a diamide moiety.
A composition comprising a non-linear stimuli-responsive block copolymer comprising a polyethylene glycol (PEG) block and a poly((2-dimethylamino)ethyl methacrylate) (PDMAEMA) block, wherein the non-linear stimuli-responsive block copolymer comprises a core region and three or more branches extending away from the core region, wherein the three or more branches comprise a branch comprising the PEG block, a branch comprising the PDMAEMA block, a branch comprising both the PEG block and the PDMAEMA block, or a combination thereof, wherein the non-linear stimuli-responsive block copolymer has a star morphology wherein the core region comprises a central molecular moiety and the three or more branches extend radially away from the core region, wherein the central molecular moiety is a sorbitan moiety, wherein the three or more branches comprise a PEG branch and multiple PEG-PDMAEMA branches, and wherein the PEG branch comprises a fatty acid moiety covalently bound to a PEG block of the PEG branch.
A composition comprising a non-linear stimuli-responsive block copolymer comprising a polyethylene glycol (PEG) block and a poly((2-dimethylamino)ethyl methacrylate) (PDMAEMA) block, wherein the non-linear stimuli-responsive block copolymer comprises a core region and three or more branches extending away from the core region, wherein the three or more branches comprise a branch comprising the PEG block, a branch comprising the PDMAEMA block, a branch comprising both the PEG block and the PDMAEMA block, or a combination thereof, wherein the non-linear stimuli-responsive block copolymer has a comb morphology wherein the core region comprises an extended, polymeric molecular chain and the three or more branches are distributed along the extended, polymeric molecular chain and extend away therefrom.
A composition comprising a non-linear stimuli-responsive block copolymer comprising a polyethylene glycol (PEG) block and a poly((2-dimethylamino)ethyl methacrylate) (PDMAEMA) block, wherein the non-linear stimuli-responsive block copolymer comprises a core region and three or more branches extending away from the core region, wherein the three or more branches comprise a branch comprising the PEG block, a branch comprising the PDMAEMA block, a branch comprising both the PEG block and the PDMAEMA block, or a combination thereof, wherein the composition further comprises pigment particles and a solvent, and further wherein the pigment particles comprise TiO2 particles.
