Název v původním jazyce

Preparation of CaCO3-based biomineralized polyvinylpyrrolidone-carboxymethylcellulose hydrogels and their viscoelastic behavior

Popis výsledku v původním jazyce

In the blend of natural and synthetic polymer based biomaterial of polyvinylpyrrolidone (PVP) and carboxymethylcellulose (CMC), fabrication of CaCO3 was successfully accomplished using Simple Liquid Diffusion technique. The present study emphasizes on the biomimetic mineralization in PVP-CMC hydrogel, and several properties of this regenerated and functionalized hydrogel membrane were investigated. The physical properties were studied and confirmed the presence of CaCO3 mineral in hydrogel by Fourier transform infrared spectroscopy and Scanning electron microscopy. Moreover, the absorptivity of water and mineral by PVP-CMC hydrogel was studied to know its absorption capacity. Further, the viscoelastic properties (storage modulus, loss modulus and complex viscosity) of mineralized and swelled samples (time: 5-150 min) were measured against angular frequency. It is interesting to know the increase of elastic nature of mineralized hydrogel filled with CaCO3 maintaining the correlation bet
