Dyeing of Polymers Using Supercritical Fluid

Supercritical Fluid Processing of Polymers

We have applied in situ FTIR, ATR-IR and photoacoustic spectroscopy to identify for the first time specific molecular interactions between CO2 and polymers that may be responsible for the plasticization of glassy polymers. The changes in IR spectra of CO2 incorporated into various polymers indicate a specific interaction between CO2 and polymer functional groups. Increased polymer segmental mob...

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Development of Molecularly Imprinted Polymers for Drug Delivery Applications Using Supercritical Fluid Technology

Molecular imprinting is an emerging field that produces precise chemical and physical architectures that can bind analytes. The technique uses the functionality of the target molecule (template) to assemble a molecular recognition site by forming specific interactions with the matrix. We have recently proposed supercritical fluid technology to replace hazardous organic solvents in the synthesis...

Supercritical Fluid Extraction+supercritical Fluid Chromatography

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...

economic evaluation of soil remediation using supercritical fluid

supercritical fluid extraction (scfe) is a soil remediation technology. at present, only a few companies are using from this method, all of which are technical based on conventional methods of extraction such as soilex solvent extraction. because of the hard enforcement of environmental conservation law, using green technology seems imperative. this paper endeavors to carry out the feasibility ...
