Grafting of a Stimuli Responsive Polymer on Nanolayered Coextruded PS/PCL Films by Surface Initiated Polymerization

surface-initiated polymerization: the characterization of polymer chain conformation, grafting density and polydispersity correlated to the grafting surface curvature

In our model, the immobile frozen particles are used to construct the spherical surface template of the NP. For a specific NP with determined radius, we first use the geodesic subdivision method to get all the vertex positions. This method is a repeated subdivision process of triangles. Starting with an icosahedron inscribed in the sphere, we first find the midpoint of each edge, and then push ...

Hierarchical Nested Wrinkles on Silica−Polymer Hybrid Films: Stimuli-Responsive Micro Periodic Surface Architectures

Stimuli-response on hierarchically-structured surface wrinkles is required for advanced filtration, catalysis and sensing applications. Although conventional processes can form hierarchical surface wrinkles, incorporation of stimuli-responsive features has not been achieved, limiting the potential multi-scale functionality of wrinkles. Here, we demonstrate a novel process that can fabricate sti...

Semiconducting polymer thin films by surface-confined stepwise click polymerization.

Surface-confined stepwise click polymerization was used to prepare surface-attached thin films of semiconducting polymers. These highly uniform films showed extended UV/vis absorption characteristics and a remarkable degree of molecular organization with a unidirectional alignment of the polymer chains normal to the surface.

Responsive PET nano/microfibers via surface-initiated polymerization.

Poly(ethylene terephthalate) (PET) is one of the most important thermoplastics in ubiquitous use today because of its mechanical properties, clarity, solvent resistance, and recyclability. In this work, we functionalize the surface of electrospun PET microfibers by growing poly(N-isopropylacrylamide) (PNIPAAm) brushes through a chemical sequence that avoids PET degradation to generate thermores...
