[Biomacromolecules] Micro/nanoscale well and channel fabrication on organic polymer substrates via a combination of photochemical and alkaline hydrolysis etchings
With the utilization of photomasks, micro/nanoscale wells and channels with depths ranging from nanometers to several micrometers were fabricated on a poly(ethylene terephthalate) (PET) surface by a simple combination of photochemical and alkaline hydrolysis etching. The PET surface region could be directly and photochemically etched by UV light and N,N-dimethylformamide (DMF) to create 125...

Fabrication of a molecular-level multilayer film on organic polymer surfaces via chemical bonding assembly
A fresh multilayer film was fabricated on a molecular level and successfully tethered to the surface of a hydroxylated organic substrate via chemical bonding assembly (CBA). Sulfate anion groups (SO4-) were preintroduced onto the surface of biaxially oriented polypropylene (BOPP) films via a reference method. Upon hydrolysis of the SO4- groups, hydroxyl groups (--OH) were formed that subseque...

Covalently attached graft polymer monolayer on organic polymeric substrate via confined surface inhibition reaction
A grafting technique was proposed for the preparation of polymer monolayer on polymeric substrate. On the basis of our recent work on polymer-supported inhibitor (PSI), hydroquinone (HQ) was first implanted onto polypropylene (PP) surface through UV-initiated grafting. The resulting immobilized HQ was used as PSI for the thermal-induced free radical polymerization (FRP) of acrylic acid (AA). ...

A Biomimetic Chemical Approach to Facile Preparation of Large-Area, Patterned, ZnO Quantum Dot/Polymer Nanocomposites on Flexible Plastics
This study reports a new biomimetic approach to fabricate ZnO quantum dots (QDs) directed by surface-immobilized acidic-polymer brushes. Through multiple characterization methods including XPS, high-resolution TEM, SEM, AFM, XRD, UV-vis absorption and fluorescence spectroscopy, we found that surface-photografted poly(acrylic acid) chains could mediate the heterogeneous nucleation and growth proces...

Facile Preparation of a Patterned, Aminated Polymer Surface by UV-light-induced Surface Aminolysis
Introducing amine functional groups on polymer surfaces is extremely important for studying various processes that involve polymer surfaces. We report a novel and extremely simple method for preparing a tertiary-amine-terminated poly(ethylene terephthalate) (PET) surface by using a UV-light-induced surface aminolysis reaction. X-ray photoelectron spectroscopy and attenuated total-reflection infrar...

Probing chain interpenetration in polymer glasses by H-1 dipolar filter solid-state NMR under fast magic angle spinning
Chain interpenetration in polymer glasses was investigated by a new strategy combining preparation of an isotopically enriched polymer blend with analysis by 1H dipolar filtered solid-state NMR under fast magic angle spinning (MAS). The fast MAS at 25 kHz induces crucial changes in spin dynamics and selectively isolates the proton signal of hydrogenous PS chains in which protons are sufficiently...

Characterization of polymer compatibility by H-1 dipolar filter solid-state NMR under fast magic angle spinning.
Polymer compatibility was investigated by a new strategy reported in our recent communication combining preparation of an isotopically enriched polymer blend with analysis by dipolar filter 1H solid-state NMR under fast magic angle spinning (MAS). Technical details concerning the optimization of the experimental conditions of this method were first discussed. The intimate segment mixing and interc...

Fluorescent conjugated polymer molecular wire chemosensors for transition metal ion recognition and signaling
Conjugated polymer molecular wires have advantages over small molecules for sensing applications due to enhancements associated with electronic communication along the polymer backbone. The majority of examples from the literature focus on fluorescence “turn-off” as the mechanism of sensor response. The energy transfer mechanism involved in these polymers focuses on energy transfe...
