Montmorillonite Nanocomposite Hydrogel Based on Poly(acrylicacid-co-acrylamide): Polymer Carrier for Controlled Release Systems
In this paper, the synthesis of new montmorillonite nanocomposite hydrogel (MMTNH) based on poly (acrylic acid-co-acrylamide) grafted onto starch, is described. Montmorillonite (MMT) as nanometer base, acrylic acid (AA) and acrylamide (AAm) as monomers, ammonium persulfate (APS) as an initiator, N,N-methylenebisacrylamide (MBA) as a crosslinker and starch as a biocompatible polymer were pre...
متن کاملComposite Hydrogels of Bacterial Cellulose - carboxymethyl Cellulose for Drug Release
Bacterial cellulose (BC) is a suitable material for biomedical applications due to its remarkable proprieties, such us: biodegradability, biocompatibility and ready availability. In this paper the swelling and drug release profiles from bacterial cellulosecarboxymethyl cellulose (BC-CMC) composite hydrogels were investigated, in the aim to use such systems in controlled drug delivery field. Ibu...
متن کاملPreparation of Micro-Crystalline Cellulose-Reinforced Polyacrylic Acid Hydrogel and its Application in Paper/Polyacrylic Acid Composites
Paper/polyacrylic acid (PAA) composites were prepared using a microcrystalline cellulose (MCC)-reinforced PAA hydrogel. The MCC-reinforced PAA hydrogel was prepared by in-situ UV light-induced polymerization of acrylic acid in the presence of MCC. The experimental results showed that the presence of MCC improved the water absorption capacity of the resulting PAA hydrogel. The addition of 1 wt% ...
متن کاملControlled - Release Fertilizers : Advances and Challenges
Controlledrelease fertilizers (CRFs) offer an excellent option to improve nutrients uptake by plants and reduce the environmental hazards due to excess release of chemicals. Polymer-coated fertilizers, compared to the other types of CRF, are by far the most intensively researched topic because of their great characteristics. Polymercoated fertilizers, which are less sensitive to the soil and en...
متن کاملNovel High Capacity Swelling Superabsorbent Composite and Its Potential for Controlled Release of Fertilizers
A hydrophilic macromolecular network is prepared by performing graft copolymerization of poly (sodium acrylate) chains onto salep and silica gel. The reaction parameters affecting the water absorbency of the superabsorbent composite were optimized using Taguchi method. FT-IR spectroscopy and Thermo Gravimetric Analysis (TGA) were used for confirming the s...
