Strategic Study of CAE 2002, Volume 4, Issue 6,   Pages 71-76

Abstract:

More than 80% of crude produced in China are those crudes with poor flowability, either waxy crudesoil, which accounts for about one third of total crude oil production in China.For heavy crude oil pipelining, it is believed that the oil-in-water emulsion technology will find moreapplication, and exploitation of offshore heavy crude oil fields in the Bohai Sea of China urgentlyrequires that study on this technology be aimed at pipelines concurrently transporting heavy crude oil

Effect of polyethylene glycol on the crystallization, rheology and foamability of poly(lactic acid) containing

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 12,   Pages 2074-2087 doi: 10.1007/s11705-023-2342-8

Abstract: In this study, the rheological properties, crystallization and foaming behavior of poly(lactic acid) with polyamide 6 nanofibrils were examined with polyethylene glycol as a compatibilizer. Polyamide 6 particles were deformed into nanofibrils during drawing. For the 10% polyamide 6 case, polyethylene glycol addition reduced the polyamide 6 fibril diameter from 365.53 to 254.63 nm, owing to the smaller polyamide 6 particle size and enhanced interface adhesion. Rheological experiments revealed that the viscosity and storage modulus of the composites were increased, which was associated with the three-dimensional entangled network of polyamide 6 nanofibrils. The presence of higher aspect ratio polyamide 6 nanofibrils substantially enhanced the melt strength of the composites. The isothermal crystallization kinetics results suggested that the polyamide 6 nanofibrils and polyethylene glycol had a synergistic effect on accelerating poly(lactic acid) crystallization. With the polyethylene glycol, the crystallization half-time reduced from 103.6 to 62.2 s. Batch foaming results indicated that owing to higher cell nucleation efficiency, the existence of polyamide 6 nanofibrils led to a higher cell density and lower expansion ratio. Furthermore, the poly(lactic acid)/polyamide 6 foams exhibited a higher cell density and expansion ratio than that of the foams without polyethylene glycol.
