Langmuir, 29, 12176–12182: Single-Chain Mechanics of Poly(N,N-diethylacrylamide) and Poly(N-isopropylacrylamide): Comparative Study Reveals the Effect of Hydrogen Bond Donors
The
single-chain mechanics of two similar thermosensitive polymers, poly(N,N-diethyl-acrylamide) (PDEAM) and poly(N-isopropyl-acrylamide) (PNIPAM), have been studied by atomic
force microscopy-based single-molecule
force spectroscopy (SMFS). In a typical nonpolar organic
solvent, octane, both the two polymers show the same
inherent elasticity, although they have different substitutional groups. ...

209. Polydopamine-coated electrospun poly(vinyl alcohol)/poly(acrylic acid) membranes as efficient dye adsorbent with good recyclability.
Free-standing poly(vinyl alcohol)/poly(acrylic acid) (PVA/PAA) membranes with polydopamine (PDA) coating were prepared based on the combination of electrospinning and self-polymerization of dopamine. This is a facile, mild, controllable, and low-energy consumption process without any rigorous restriction to reactive conditions. Benefiting from the high specific surface area of electrospun membrane...

Synthesis and micellization of amphiphilic multi-branched poly(p-dioxanone)-block-poly(ethylene glycol)
A novel multi-branched crystalline-coil block copolymer composed of hydrophilic polyethylene glycol (PEG) block and multi-branched crystallisable poly(p-dioxanone) (PPDO) block was prepared. Firstly, multi-branched PPDO was prepared via polycondensation of AB2-type HOOC-PPDO-2OH precursor, which was synthesized by using 2,2-bis(hydroxymethyl) propionic acid as initiator for ring opening polymeri...

Well-Defined Amphiphilic Poly(p-dioxanone)-grafted Poly(vinyl alcohol) Copolymers: Synthesis and Micellization
A series of amphiphilic biodegradable and biocompatible poly(p-dioxanone)-grafted poly(vinyl alcohol) (PVA) copolymers with well-defined structure were obtained by a three-step synthesis based on the "grafting from" concept. The first step (protection step), called the partial silylation of PVA hydroxyl groups, was accomplished by 1,1,1,3,3,3-hexamethyl-disilazane and catalyst chlorotrimethylsilan...

Thermal properties and non-isothermal cry-stallization behavior of biodegradable poly(p-dioxanone)/poly(vinyl alcohol) blends
Blends of two biodegradable semicrystalline polymers, poly(p-dioxanone) (PPDO) and poly(vinyl alcohol) (PVA) were prepared with different compositions. The thermal stability, phase morphology and thermal behavior of the blends were studied by using thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). From the TGA data, it can be seen tha...

Copolymerization of poly (vinyl alcohol)-graft-poly (1, 4-dioxan-2-one) with designed molecular structure by a solid-state polymerization method
Poly(vinyl alcohol)-graft-poly(1,4-dioxan-2-one) (PVA-g-PPDO) with designed molecular structure was synthesized by a solid-state polymerization. The solid-state copolymerization was preceded by a graft copolymerization of PDO initiated with PVA as a multifunctional initiator, and Sn(Oct)(2) as a coininitiator/catalyst in a homogeneous molten state. The polymerization temperature was then decreased...

Green Poly(ε-caprolactone) Composites Reinforced with the Electrospun Polylactide/Poly(ε-caprolactone) Blend Fiber Mats
ACS Sustainable Chemistry & Engineering 2014, 2(9), 2102-2110
ABSTRACT:
As two typical aliphatic polyesters, biodegradable poly(ε-caprolactone) (PCL) and polylactide (PLA) show quite different mechanical properties. Compounding them together is therefore an interesting topic on the fabrication of biomaterials with tailorable properties. The composite technology was used in...

Synthesis and drug release of star shape poly(benzyl L-aspartate)-b-poly(ethylene glycol) copolymers with POSS cores
Star shape amphiphilic block copolymers with polyhedral oligomeric silsesquioxanes as cores were synthesized using the “arm-first” strategy. Firstly, the block copolymer poly(benzyl L-aspartate)-b-poly(ethylene glycol) (PBLA-b-PEG) was synthesized via ring-opening polymerization of β-benzyl L-aspartate-N-carboxyanhydride (BLA-NCA) with α-Methoxy-ω-aminopoly(ethylene glycol) (mPEG-NH2) as a ma...

Drug release of pH-sensitive poly(L-aspartate)-b-poly(ethylene glycol) micelles with POSS cores
Amphiphilic poly(L-aspartate)-b-poly(ethy1ene glycol) block copolymers were synthesized and immobilized on polyhedral oligomeric silsesquioxanes (POSS) to receive star shape copolymers. 1-(3-Aminopropyl) imidazole was conjugated on the pendant groups of poly(L-aspartate) segments to fabricate pH-sensitive micelles. Anticancer drug doxorubicin (DOX) was trapped in the micelles to investigate the ef...
