i should disperse dextran particles in PLA solution. i used DCM: methanol (70:30 and 80: 20) but fiber was not fabricated. which solvents can be used?
thanks.( i can not use DMF as co-solvent because solubility of dextran)
Tetrahydrofuran (THF) and Dextran in methyl sulfide, formamide, ethylene glycol, and glycerol
Tetramethylsilane(TMS)
TRY FOR HFIP AND TIFE
thanks for help,
dear helen, i can not use DMF , it dissolves dextran.
unfortunately i could not open your pdf file.
also HFIP is especial and very expensive. are there another general and lower price solvents?
best regards.
