[ 1 ] - Microwave-Assisted Synthesis of kappa-Carrageenan Beads Containing Silver Nanoparticles with Dye Adsorption and Antibacterial Properties
In this work, we used a simple and totally green method for synthesizing silver nanoparticles using kappa-carrageenan as reducing and stabilizing agent. The beads were prepared in aqueous medium by microwave heating, and then followed by cross-linking with K+ cations without using any additional toxic and expensive chemical agents. The preparation method of the carrageenan-based beads is easy, ...
[ 2 ] - Preparation and Characterization of a Cotton-Based Nanocomposite Hydrogel
In this work, hydrogel nanocomposites were synthesized by solution polymerization of acrylic acid (AA) and itaconic acid (IA) in the presence of cotton fabric. Ammonium persulfate (APS) was used as the polymerization initiator in the presence of a crosslinker, methylene bisacrylamide (MBA). Insertion of Ag followed by reduction of Ag+ cations results in a hydrogel nanocomposite. The ...
[ 3 ] - 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 ...
[ 4 ] - Magnetic/pH-sensitive nanocomposite hydrogel based carboxymethyl cellulose –g- polyacrylamide/montmorillonite for colon targeted drug delivery
Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide (MBA) as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and magnetic montmorillonite ( mMT) nanoclay as nano-...
[ 5 ] - تهیه، شناسایی ساختار و ویژگی ضدباکتری نانوچندسازه‌های پلی(آنترانیلیک اسید)/نقره
نانوچندسازه‌ها نیز به‌عنوان یکی از شاخه‌های این فناوری، اهمیت بسیاری یافته‌اند. در پژوهش حاضر، نانوچندسازه‌های پلی(آنترانیلیک اسید)/نانوذره‌های نقره با روش بسپارش اکسایشی درجا با ویژگی ضدباکتری تهیه شد. ساختار نانوچندسازه‌های تهیه‌شده با روش‌های طیف‌سنجی فروسرخ تبدیل فوریه (FTIR)، طیف‌سنجی تفکیک انرژی (EDS)، پراش پرتو ایکس (XRD)، میکروسکوپی الکترونی روبشی (SEM)، میکروسکوپی الکترونی عبوری (TEM) ...
