PVA based hydrogel was synthesised using, as crosslinking agent, trisodium trimetaphosphate (STMP) and its morphology was modified inducing a microporous structure to obtain potential substitutes for cartilage tissue. The hydrogel was characterised by Infrared Spectroscopy combined with Time of flight mass spectrometry (ToF‐SIMS) that confirmed the successful occurrence of crosslinking reaction, the...
To overcome opacification and absence of accommodation of human lens substitutes a new poly(vinyl alcohol) (PVA)/poly(N‐vinyl‐2‐ pyrrolidinone) (PVP) based hydrogel (PPS31075) was realised. The Infrared Spectroscopy and the mechanical spectra confirmed the successful occurrence of crosslinking reaction. The rheological analysis pointed out a behavior comparable with that of young human lens in terms...
