A novel naturally superoleophilic coconut oil-based foam with inherent hydrophobic properties for oil and grease sorption

open access: yesScientific Reports
Absorption methods using polyurethane foams (PUFs) have recently gained popularity in treating oil spills. However, conventional petroleum-based PUFs lack selectivity and are commonly surface-modified using complicated processes that require toxic and ...

From Commodity Polymers to Functional Polymers [PDF]

open access: yesScientific Reports, 2014
Functional polymers bear specified chemical groups, and have specified physical, chemical, biological, pharmacological, or other uses. To adjust the properties while keeping material usage low, a method for direct synthesis of functional polymers is indispensable.

Value-Added Products Derived from Poly(ethylene terephthalate) Glycolysis

open access: yesMolecules
Among polymer wastes, poly(ethylene terephthalate) (PET) is the most important commercial thermoplastic polyester. Less than 30% of total PET production is recycled into new products. Therefore, large amounts of waste PET need to be recycled. We describe

Ignition mechanisms in polymers and polymer nanocomposites [PDF]

open access: yesPolymers for Advanced Technologies, 2011
This paper addresses the behavior of thermoplastic polymers and polymer nanocomposites prior to ignition, under irradiation in a cone calorimeter. Insights into the physical evolution of material controlling ignition are obtained from the measurement of the condensed phase surface temperature and by the observation of specimen residues obtained from ...
