Özet:

 


In
this study, a series of gelatin coated sodium
alginate (Na-Alg) hydrogels were prepared. Firstly, three types
of hydrogels in bead form were obtained
by using the classical ionic crosslinking method of Na-Alg with calcium chloride (CaCl2). Second group was a series of Na-Alg
hydrogel beads coated with gelatin. The immersing method was used to get the
coated beads. The hydrogel samples were diversified by changing the
concentrations of gelatin and CaCl2 solutions. The percentages of
Na-Alg solution was kept constant at 10%. Swelling tests of all hydrogel beads
were gravimetrically carried out in buffer solution at pH=7.0 and swelling
percentages were calculated.  It is found
that swelling value is decreased by increasing of CaCl2 from 5% to
30%. In general, the hydrogels prepared using 5% of crosslinker were unstable.
Coating conditions of Na-Alg hydrogel were varied by changing gelatin
concentrations from 10% to 20%. The increasing amount of gelatin in coated part
causes the decreasing in swelling values of hydrogel beads.
