Polyelectrolyte complex (PEC) hydrogels composed of chitosan as a cationic polyelectrolyte and poly (γ‐glutamic acid) (γ‐PGA) as an anionic polyelectrolyte were prepared from PEC dispersions based on a chitosan solution to which different amounts of γ‐PGA solutions were added to charge equivalency.

Hydrogels formed by polyelectrolyte complexation (PEC) of oppositely charged biopolymers, free of any chemical additives, are promising biomaterials. In this work, the mechanical behavior of hydrogels consisting of positively charged chitosan and negatively charged sodium hyaluronate (HA) at balanced charge composition is investigated. These hydrogels exhibit strong tensile strain and strain

Recent Advances in Nanocellulose Composites with Polymers
2.1. Cellulose Nanocrystal (CNC) From the 1940s to the 1950s, Nickerson and Habrle first observed the degradation of cellulosic fibers in boiling acidic solutions [] and, subsequently, Ranby performed the controlled sulfuric acid hydrolysis of cellulosic fibers, finally obtaining the colloidal suspension of cellulosic crystals [24,25].The transmission electron microscopic (TEM) observation of ...
The invention relates to living cells encapsulated in a membrane. The membrane is a complex formed by the cohesion of two polymer layers. An inner layer comprises a substrate biopolymer and an outer layer comprises a synthetic polyelectrolyte having an electrolytic charge opposite that of the substr.....

- What is anionic polyacrylamide (Apam)?
- 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- What is the active ingredient of Pam?
- Anionic PAM is the active ingredient. Only products using water soluble anionic PAM as the active polymer ingredient should be used. Products containing a synthetic cationic polymer or chitosan should not be used due to their higher toxicity to aquatic organisms. Site Specific Performance Testing.
- Is Apam a uniform polymer?
- The polyacrylamide is a uniform and unitary polymer. PAM has a neat smooth surface as its SEM images unfold at 2500x and 4000x. However, the surface of APAM was much rougher. Hills and valleys could be observed in its SEM images due to the interaction of chemical groups between AM and SAS.
