Poly(vinylidene fluoride-co-tetrafluoroethylene) (PVDF-TFE) is confined between alternating layers of poly(ethylene terephthalate) (PET) utilizing a unique multilayer processing technology, in which PVDF-TFE and PET are melt-processed in a continuous fashion. Postprocessing techniques including biaxial orientation and melt recrystallization were used to tune the crystal orientation of the PVDF-...

in this research, the influence of chemical composition of slags and the melting rate on the impurity of commercial grade iron in esr processing has been investigated.the chemical composition and microstructure studies were evaluated, using spectrophotometer,omand edx analyses attached to sem.the results show that esr process has successfully reduced the amount and size of inclusions. in some c...

High-performance polymers that have improved processing characteristics, and a method of making them, have been invented. One of the improved characteristics is low (relative to corresponding prior polymers) melt viscosities at given temperatures. This characteristic makes it possible to utilize such processes as resin-transfer molding and resin-film infusion and to perform autoclave processing...

An advanced SiO2–lignin hybrid material was obtained and tested as a novel poly(vinyl chloride) (PVC) filler. The processing of compounds of poly(vinyl chloride) in the form of a dry blend with silica–lignin hybrid material and, separately, with the two components from which that material was prepared, was performed in a Brabender mixing chamber. An analysis was made of processing (mass melt fl...

Focusing on the challenge of non-biodegradable plastics replacement, we propose a design for peroxide-initiated crosslinking biodegradable poly(ε-caprolactone) (PCL) and renewable cellulose nanocrystals (CNCs) bionanocomposites. An industrially scalable water-assisted reactive melt-processing (REx) is studied to explore hypothesis synergy between simultaneous effects water improving CNC dispers...

Reactive processing combines melt mixing process and chemical reaction simultaneously. TPVs are produced by such reactive processing. Polymer modification with high energy electrons is based on generation of excited atoms or molecules and ions for subsequent molecular changes via radical induced chemical reactions. In the present study, electron induced reactive processing is used for the devel...

The application of melt spinning processes for the production of cellulosic fibres would be a significant sign of progress for economic and environmental reasons. A process for melt spinning of trimethyl-silycellulose (TMSC) was developed. Bis(trimethyl-)silylcarbamate (BSC) was found to be excellent for the silylation of cellulose due to good swelling and penetration into cellulose. The synthe...

Bi-2212rAg tapes with a thickness of 30 mm were melt-grown in elevated magnetic fields following two different thermal sequences. The transport critical current density, J dependence on the maximum processing temperature, cooling c rate, holding time and magnetic field was studied systematically. The quantity of impurity phase was decreased by reducing the holding time above the melting point o...
