Amphibious fluorescent carbon dots: one-step green synthesis and application for light-emitting polymer nanocomposites
A facile and green approach for the synthesis of amphibious fluorescent carbon dots (CDs) from natural polysaccharide is reported. Lightemitting polymer nanocomposites with excellent optical performance can be easily prepared by incorporation of the amphibious CDs into the polymer matrix.

Synthesis of cerium N-morpholinomethylphonic acid and its flame retardant application in high density polyethylene
Cerium N-morpholinomethylphonic acid (MMPA-Ce) with fibrous structure was synthesized via hydrothermal reaction between cerium nitrate hexahydrate and N-morpholinomethylphonic acid. The flame retardancy of high density polyethylene (HDPE) containing various amount of MMPA-Ce was investigated by cone calorimeter. The peak value of heat release rate (PHRR) of HDPE obviously decreased when adding MMP...

121. Synthesis of a novel ionic liquid containing phosphorus and its application in intumescent flame retardant polypropylene system
A novel ionic liquid containing phosphorus ([PCMIM]Cl) was synthesized and characterized by FTIR, 1H NMR, 13C NMR and 31P NMR. Moreover, a new intumescent flame retardant (IFR) system, which was composed of [PCMIM]Cl and ammonium polyphosphate (APP), was used to impart flame retardancy and dripping resistance to polypropylene (PP). The flammability and thermal behaviors of intumescent flame-retard...

Synthesis and characterization of a pentaerythritol-based amphiphilic starblock copolymer and its application in controlled drug release
A star-like amphiphilic copolymer was synthesized via RAFT polymerization by using a pentaerythritolbased
compound (PTDBA) as a chain transfer agent with Styrene and DMAEMA as monomers. The polymer
structure was characterized by FTIR, 1H NMR, 13C NMR and SEC/MALLS. After the retardation period,
the molecular weight of PS-CTA and PMMA-CTA increased linearly with monomer conversion. The
amphiphi...

Synthesis of Macroporous Polymer through Heterogeneous Polymerization by Redox Initiator and Application as Scaffold for Pd Nanoparticles
Heterogeneous polymerization of the binary hydrophilic/hydrophobic monomers initiated by the redox pair to synthesize macroporous amphiphilic copolymers is reported. This strategy employs the initiator of the hydrophilic/hydrophobic redox pair of K2S2O8/1-octylamine or the hydrophilic/hydrophilic redox pairs of K2S2O8/diethylamine and K2S2O8/Na2SO3 to initiate the polymerization on the O/W emulsio...

Surface modification of potassium titanate whisker and its application to thermal insulation coil coatings
Potassium titanate whiskers (PTW) were modified by silane coupling agent KH-570 before and after coating with inorganic SiO2. The influence of the PTWs modified by silane coupling agent before and after coating with SiO2 on thermal insulation performance of coil coating were compared. PTWs before and after modification were characterized by infrared (IR) spectroscopy and thermo-gravimetry (TG). Th...

Synthesis of efficient and reusable palladium catalyst supported on pH-responsive colloid and its application to Suzuki and Heck reactions in water
www.sciencedirect.com/science/article/pii/S002195170700262X
An efficient and reusable pH-responsive colloid supported palladium catalyst was synthesized by loading 3-nm Pd nanoparticles into the pH-responsive colloid of core–shell microspheres of poly[styrene-co-2-(acetoacetoxy)ethyl methacrylate-co-methyl acrylic acid] (PS-co-PAEMA-co-PMAA). The colloidal scaffold of the core–shell m...

Synthesis of gold nanoparticles stabilized with poly(N-isopropylacrylamide)-co-poly(4-vinyl pyridine) colloid and their application in responsive catalysis
www.sciencedirect.com/science/article/pii/S1381116907005870
The copolymer of poly(N-isopropylacrylamide)-co-poly(4-vinylpyridine) was synthesized by free radical copolymerization of 4-vinylpyridine and N-isopropylacrylamide. The copolymer synthesized with the feed monomer ratio of 4-vinylpyridine/N-isopropylacrylamide equal to 1/3 was associated to form thermoresponsive colloid in neutral water a...
