Gels derived from single networks of natural polymers (biopolymers) typically exhibit limited physical properties and thus have seen constrained applications in areas like food medicine. In contrast, gels founded on a synergy multiple biopolymers, specifically polysaccharides proteins, with intricate interpenetrating polymer network (IPN) structures, represent promising avenue for the creation novel gel materials significantly enhanced combined advantages. This review begins scrutiny newly devised IPN formed through medley and/or alongside an introduction their practical realm food, medicine, environmentally friendly solutions. Finally, based fact that gelation process mechanism are driven by different inducing factors entwined diverse amalgamation our survey underscores potency physical, chemical, enzymatic triggers orchestrating construction crosslinked within these biomacromolecules. mixed systems, each specific inducer aligns distinct culminating generation semi-IPN or fully-IPN interpenetration between chains two networks, respectively. The resultant stand as paragons excellence, characterized homogeneity, dense superior textural (e.g., hardness, elasticity, adhesion, cohesion, chewability), outstanding water-holding capacity, heightened thermal stability, along guaranteed biosafety nontoxicity biocompatibility) biodegradability. Therefore, judicious selection combinations allows development customized functional properties, adept at meeting precise application requirements.

Characterization Methods to Determine Interpenetrating Polymer Network (IPN) in Hydrogels

Polymers, Journal Year: 2024, Volume and Issue: 16(14), P. 2050 - 2050

Published: July 18, 2024

Significant developments have been achieved with the invention of hydrogels. They are effective in many fields such as wastewater treatment, food, agriculture, pharmaceutical applications, and drug delivery. Although hydrogels used successfully these areas, there is a need to make them better for future applications. Interpenetrating polymer networks (IPNs) can be created more adjustable suitable specific purpose. IPN formation an innovative approach polymeric systems. It brings two or together entanglements. The properties IPNs controlled by its chemistry, crosslinking density, morphology. Therefore, it necessary understand characterization methods order detect structure develop In recent studies, has determined via chemical, physical, mechanical Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, scanning electron microscopy (SEM), field emission (FESEM), differential calorimetry (DSC), dynamic analysis (DMA), X-ray diffraction (XRD), rheology methods. this paper, will explained, studies scrutinized, effectiveness confirm evaluated.

Sodium-alginate/poly (acrylamide co-acrylic acid) semi-interpenetrating hydrogels for removal of heavy metals from aqueous solutions

Journal of Polymer Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: April 4, 2025

Abstract Water contamination by heavy metals is a serious ecological problem due to their toxicity humans, animals and plants. The synthesis of new low-cost adsorbents used in the treatment polluted water therefore generating growing interest. In this work, semi-interpenetrating network (SIPN) hydrogels in-situ free radical polymerization was carried out. Materials based on poly(acrylamide-co- acrylic acid) different ratios sodium alginate (Alg-Na) have been prepared examine potential use wastewater treatment. swelling capabilities these materials were evaluated observing general trend low acidic pH solutions more significant with above 5. structure morphology investigated using X-ray diffraction, Fourier transform infrared spectroscopy scanning electron microscopy. adsorption capacity for metal ions Pb 2+ , Cd Cr 3+ studied aqueous media containing concentrations (25–100 ppm). results showed that great removal from concluding also addition Alg-Na enhances uptake.
