Facile Preparation of Novel Peptosomes through Complex Self-Assembly of Hyperbranched Polyester and Polypeptide,
This work reported for the first time a facile template-free method to
prepare polypeptide-based vesicles (peptosomes) through one-step complex
self-assembly of carboxyl-terminated hyperbranched polyester and
cationic poly-l-lysine (PLL). The
preparation of such peptosomes, named complex peptosomes (CPs) here, is
very simple just by mixing two kinds of polymer aqueous solutions
togethe...

SoftMatter--Redox control of GPx catalytic activity through mediating self-assembly of Fmoc-phenyalanine selenide into switchable supramolecular architectures
Artificial enzymes capable of achieving tunable catalytic activity through stimuli control of enzymatic structure transition are of significance in biosensor and biomedicine research. Herein we report a novel smart glutathione peroxidise (GPx) mimic with modulatory catalytic activity based on redox-induced supramolecular self-assembly. First, an amphiphilic Fmoc-phenylalanine-based selenide was de...

Study on the influence of reaction time on the structure and properties of the PVDF membrane modified through the method of atom transfer radical polymerization
A thermo-responsive membrane, PVDF-g-PNIPAAm, was successfully prepared from poly(vinylidene fluoride) (PVDF) membrane through surface-initiated atom transfer radical polymerization (ATRP) of a thermo-responsive monomer, N-isopropyl acrylamide (NIPAAm). The influence of the reaction time on ATRP was studied in detail. The grafting membrane was characterized by scanning electron microscopy (SEM), F...

139. Supertough Polylactide Materials Prepared through In Situ Reactive Blending with PEG-Based Diacrylate Monomer
Supertough biocompatible and biodegradable polylactide materials were
fabricated by applying a novel and facile method involving reactive
blending of polylactide (PLA) and poly(ethylene glycol) diacylate
(PEGDA) monomer with no addition of exogenous radical initiators. Torque
analysis and FT-IR spectra confirm that cross-linking reaction of
acylate groups occurs in the melt blending process a...

Halogen-free flame retardant poly (vinyl alcohol) foams prepared through thermal processing
Novel
halogen-free flame retardant PVA-based composite foams were successfully prepared
through continuous extrusion foaming using water as plasticizer and blowing
agent. The morphology, cellular structure and flame retardancy of
the prepared PVA foams were investigated. It was found that the halogen-free flame retardant containing
nitrogen-phosphorus (NPCs) were well dispersed in PVA matrix due...

Poly (vinyl alcohol)/melamine phosphate composites prepared through thermal processing: thermal stability and flame retardancy
Abstract: Poly
(vinyl alcohol)/melamine phosphate composites (PVA/MP) as a novel halogen-free flame retardant foam
matrix were
prepared through thermal processing, and then their
thermal stability and flame retardancy were investigated by thermo-gravimetric
analysis (TGA), micro-scale combustion calorimeter (MCC), cone calorimeter, vertical burning test and limiting oxygen index test
(LOI). It was...

Realizing the simultaneously improved toughness and strength of ultra-thin LLDPE parts through annealing
Ultra-thin LLDPE parts were prepared by microinjection molding. Mechanical properties and microstructure
of samples before and after annealing at different temperatures (60, 80, 100 C) were analyzed.
Tensile test indicates that toughness has been enhanced at least 7 times after being annealed in parallel
with significant increase of tensile strength. Microstructure characterizations, including di...
