Improvement of Flame Retardancy of Polyurethane Foam Using DOPO-Immobilized Silica Aerogel
نویسندگان
چکیده
In this work, silica aerogel was modified by 9,10-dihydro-9-oxa-10-phosphaphenanthrene-1-oxide (DOPO). Then DOPO-immobilized nanoparticles were used as a flame retardant to prepare flame-retardant polyurethane foams. Microscale combustion calorimeter and cone tests employed evaluate the retardancy of It found that both heat release rate total composites reduced with incorporation DOPO immobilized aerogel. is speculated can inhibit degradation catalyze formation carbonaceous carbon on surface.

Optimization of Biodiesel Production Using Immobilized Candida Rugosa Lipase on Magnetic Fe3O4-Silica Aerogel
Hydrophobic magnetic silica aerogel was used as a support to immobilize Candida rugosa lipase by adsorption method. Physical and chemical properties of the support and immobilized lipase were determined by Field Emission Scanning Electron Microscope (FESEM), Brunauer–Emmett–Teller (BET) analysis and Fourier Transform InfraRed (FT-IR) spectroscopy and the results showed that the lipase was s...

Degradation of dimethylphthalate by cells of Bacillus sp. immobilized in calcium alginate and polyurethane foam.
A Bacillus sp. which is capable of degrading dimethylphthalate (DMP) was immobilized in calcium alginate and polyurethane foam for efficient and long term degradation of DMP. Freely suspended cells (10(12) cfu ml-1) degraded a maximum of 20 mM DMP. Whereas, alginate-(10(12)cfu g-1 beads) and polyurethane foam-entrapped (0.34 x 10(6-9) cfu g-1 foam cubes) cells degraded a maximum of 40 mM DMP wi...
