Title

THE RELATIONSHIP BETWEEN SWELLING AND SALT SENSITIVITY FACTOR OF HYDROGELS AND IMPROVEMENT WITH NANOCOMPOSITE

Pages

  -

Abstract

 NANOBENTONITE HYDROGELS WERE INVESTIGATED VERSUS CONVENTIONAL HYDROGELS FOR THE PURPOSE OF HIGH AMOUNT OF EQUILIBRIUM SWELLING RATIO AND LOW AMOUNT OF SALT SENSITIVITY FACTOR OF THE GELS USING CENTRAL COMPOSITE DESIGN METHOD. HYDROGELS WERE PREPARED BY CROSSLINKING OF AQUEOUS SOLUTIONS OF SULFONATED POLYACRYLAMIDE WITH CR (OAC)3. THE RESULTS SHOWED HIGH RATIO OF CR (OAC)3/POLYMER (0.5) AND HIGH CONCENTRATIONS OF POLYMER (>27, 000 PPM) WERE SUITABLE AREA FOR CONVENTIONAL HYDROGELS BECAUSE OF MINIMUM SALT SENSITIVITY FACTOR BUT LOW ABILITY OF GEL SWELLING IN BOTH DISTILLED AND FORMATION WATER WAS STILL A PROBLEM. THE RESULTS OF NANOBENTONITE HYDROGELS SHOWED THAT THEY CAN USE AS THE BEST SOLUTION WITH COMPOSITION OF POLYMER CONCENTRATIONS LESS THAN 6500 PPM AND CR (OAC)3/POLYMER RATIOS OF 0.07 TO 0.16 WHILE A SIGNIFICANTLY HIGH AMOUNT OF SWELLING AND LOW AMOUNT OF SALT SENSITIVITY FACTOR CAN BE OBSERVED INDICATING A SUITABLE CONDITION FOR FIELD OPERATION.
