Dissipative particle dynamics study on the multicompartment micelles self-assembled from the mixture of diblock copolymer poly(ethyl ethylene)-bolck-poly(ethylene oxide) and homopolymer poly(propylene oxide) in aqueous solution
Dissipative particle dynamics (DPD) method is applied to model the self-assembly of diblock copolymer poly(ethyl ethylene)-block-poly(ethylene oxide) (PEE-b-PEO) and homopolymer poly(propylene oxide) (PPO) in aqueous solution. In this study, several segments are coarse-grained into a single simulation bead based on the experimental density. For the self-assembly of pure diblock copolymer PEE-b-PEO...

Synthesis of Star-shaped Poly(ε-caprolactone)-b- poly(L-lactide)-b- poly(D,L-lactide-co-glycolid) from Hexakis[p-(hydroxymethyl)phenoxy]cyclotriphosphazene Initiator via Ring-Opening Polymerization
Hexaarmed star-shaped hydroxyl-terminated
poly(e-caprolactone) (PCL) was successfully synthesized via
the ring-opening polymerization of e-caprolactone (CL) with
hexakis[p-(hydroxymethyl)phenoxy]cyclotriphosphazene initiator
and stannous octoate catalyst in bulk. The star-shaped
PCL with hydroxy end groups could be used as amacroinitiator
for block copolymerization with L-lactide (L-LA). The...

Synthesis and characterization of well-defined ABC 3-Miktoarm star-shaped terpolymers based on poly(styrene), poly(ethylene oxide), and poly(caprolactone) by combination of the living anionic polymerization with the ring-opening polymerization.
A series of well-defined ABC 3-Miktoarm star-shaped terpolymers [Poly(styrene)-Poly(ethylene oxide)-Poly(e-caprolactone)](PS-PEO-PCL) with different molecular weight was synthesized by combination of the ‘‘living’’ anionic polymerization with the ring-opening polymerization (ROP) using macro-initiator strategy. Firstly, the ‘‘living’’ poly(styryl)lit...

Langmuir 2015: Effects of Water on the Single-chain Elasticity of poly(U) RNA
关键字：RNA
Water,
the dominant component in the physiological condition, is a complicated
solvent, which greatly affects the properties of solute molecules. Here, we utilize
atomic force microscope-based single-molecule force spectroscopy to study the
influence of water on the single-molecule elasticity of an unstructured
single-stranded RNA (poly(U)). In nonpolar solvents, RNA presents its inherent
elastici...

Single-chain mechanics of poly(N-isopropyl-acrylamide) in the water/methanol mixed solvent
关键字：PNIPAM
The variation of the single-chain mechanics of PNIPAM for the entire
range of the methanol molar fraction (χmethanol) (0 ~
100%) in the water/methanol mixed solvent have been studied by AFM-based single-molecule
force spectroscopy at RT. In general, the single-chain mechanics of PNIPAM
shows a reentrant variation upon the change of χmethanol from 0 to
100%. The possible mechanism for the re...

Unexpected Temperature-dependent Single Chain Mechanics of Poly(N-isopropyl-acrylamide) in Water
关键字：PNIPAM
Poly(N-isopropyl-acrylamide) (PNIPAM) is a paradigm
thermal sensitive polymer, which has a lower critical solution temperature
(LCST) around 32oC in water. Herein by AFM-based single molecule
force spectroscopy (SMFS), we measured the single chain elasticity of PNIPAM
across the LCST in water. Below LCST, the force curves obtained at different
temperatures have no remarkable difference; while abov...
