Biodegradable sodium alginate and lignosulphonic acid blends: characterization and swelling studies

Mass Transfer Characteristics of Sodium Alginate (SA) and Lignosulphonic acid (LS) Blends

Diffusion and sorption of Biodegradable blends of sodium alginate (SA) and lignosulphonic acid (LS) has been studied at room temperature by conventional weight gain experiments. The sorption studies of SA/LS blends are carried in pH medium of 7.4. The sorption data are used to evaluate the mass transfer coefficients such as intrinsic diffusion coefficient and permeation coefficient. It was obse...

Biodegradable Nanocomposite Films Based on Sodium Alginate and Cellulose Nanofibrils

Biodegradable nanocomposite films were prepared by incorporation of cellulose nanofibrils (CNF) into alginate biopolymer using the solution casting method. The effects of CNF content (2.5, 5, 7.5, 10 and 15 wt %) on mechanical, biodegradability and swelling behavior of the nanocomposite films were determined. The results showed that the tensile modulus value of the nanocomposite films increased...

A new biodegradable blends prepared from polylactide and hyaluronic acid

In this article, the biodegradable polylactide/hyaluronic acid (PLA/HA) composites were prepared by a melt blending method. In addition, the acrylic acid grafted polylactide (PLA-g-AA) was studied as an alternative to PLA. The samples were characterized by a fourier transform infrared (FTIR) spectroscopy, a nuclear magnetic resonance (NMR), a differential scanning calorimetry (DSC), an Instron ...

Biodegradable Polymers: Blends of Starch and Poly(lactic) Acid

Synthesis, characterization and swelling behavior investigation of gelatin-g-Poly(Acrylic Acid-co-Itaconic Acid)

A novel pH-responsive superabsorbent hydrogel based on gelatin was prepared through crosslinking copolymerization of poly (acrylic acid) and poly (itaconic acid). The copolymerization conditions including monomers, initiator, gelatin and crosslinker concentration, reaction temperature, and neutralization percent were systematically optimized to achieve a hydrogel with swelling capacity as high ...
