138. Dramatically Enhanced Mechanical Performance of Nylon-6 Magnetic Composites with Nanostructured Hybrid One-Dimensional Carbon Nanotubes – Two-Dimensional Clay Nanoplatelet Heterostructures
Mechanically robust, magnetic nylon-6 nanocomposites reinforced by one-dimensional (1D) carbon nanotube (CNT)−two-dimensional (2D) clay nanoplatelet hybrids have been prepared using a simple melt-compounding technique. The direct iron-catalyzed chemical vapor deposition (CVD) growth of multiwalled CNTs utilizes iron oxide-immobilized clay nanoplatelets as substrates, carrying out in situ int...

Highly Efficient One-Pot Synthesis of COS-Based Block Copolymers by Using Organic Lewis Pairs
关键字：metal-free Lewis pairs，poly(monothiocarbonate) block copolymer，carbonyl sulfide，immortal polymerization
A one-pot synthesis of block copolymer with regioregular poly(monothiocarbonate) block
is described via metal-free catalysis. Lewis bases such as guanidine, quaternary onium salts,
and Lewis acid triethyl borane (TEB) were equivalently combined and used as the catalysts. By using polyethylene glycol (PEG) as the macromolecular chain transfer agent (CTA), narrow polydispersity block copolym...

Synthesis of monodisperse, large scale and high solid content latexes of poly(n-butyl acrylate) by a one-step batch emulsion polymerization
关键字：Emulsion polymerization Large particle size High solid content
Seeded emulsion polymerization and agglomerating method were well-known techniques for the production of polymeric latexes with large particle size and high solid content.
Obtaining latexes with monodisperse and particle size above 300 nm scale, however, was time-consuming and difficult by means of these methods. Here, stable, monodisperse
latexes with the controlled particle diameter (55–650 nm)...

A New Low-Bandgap Polymer Containing Benzene-Fused Quinoxaline: Significantly Enhanced Performance Caused by One Additional Benzene Ring
关键字：benzene-fused quinoxaline; low-bandgap; polymer solar cells
Two new alkoxy-substituted quinoxaline (Qx)-based copolymers, PBDTQx and PBDTPz, are
designed and synthesized. The only difference between these two polymers is that two methyl groups of the Qx are replaced by one additional fused benzene ring. The UV–Vis absorptions, thermal stability, energy levels, fi eld-effect carrier mobility, and photovoltaic characteristics of the two copolymers are sys...

One-Step Synthesis of a Thienylenepyridazinylenethienylene-based Coil-Rod-Coil Copolymer with Enhanced Emission and Improved Fluorescence Stability
关键字：aggregation锛宐lock copolymers锛宑onjugated polymers锛宖luorescence锛宱ligomers
A new coil-rod-coil copolymer is synthesized via Sonogashira coupling using one-step methodology. The copolymer PEG-OEPETPT-PEG constitutes of poly(ethylene glycol) (PEG) as the coil block, and oligo[p-(ethynylenephenyleneethynylene)-alt-(thienylenepyridazinylenethienylene)] (OEPETPT) as the rod segment. The conjugated polymer PEPETPT with the same conjugated building blocks is also synthesized fo...
