creating complex polyacrylamide hydrogel structures using 3d
raised strips of stiff polyacrylamide 300 μm in height are created by 3d printing onto a glass coverslip (a, b, grey regions). the space between raised strips is then filled in with soft polyacrylamide (a, b, blue regions). which contains 0.2 μm fluorescent beads for visualization.
a comprehensive investigation of nanocomposite polymer,moreover, the polymer viscosity was improved by 73%, 48%, and 12% for hpam-sio 2 , hpam-al 2 o 3 , and hpam-zro 2 respectively under the investigation range of salinity. nanocomposites are also found to be a remarkable agent for reducing interfacial tension and changing the contact angle.

nonion, anionic polymer flocculant. effective for sedimentation of suspended substances in various types of wastewater (water, paper, pulp, metal, civil engineering, mining, ceramics, chemicals, food, and other industries), pressure flotation, etc. nonion：suitable for drainage in the acidic to neutral range.
polyelectrolyte in philippines anionic flocculant in,a flocculant is essentially a solid liquid separating agent while a deflocculant is a dispersing agent. high molecular weight flocculants are capable of promoting flocculation by neutralizing the superficial electric charges of sludge particles in the water and destabilising each individual particle.

- Which cationic polymer has the best flocculation efficiency?
- The PAmPTAC polymer had an optimal dose at 252 mg/g dry biomass. The difference in flocculation efficiency between two polymers is likely due to the differences in molecular weight. In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation.
- Can cationic polymer flocculants be developed by photo-polymerization?
- In this study, we utilized recent developments in the photo-polymerization technique to develop two cationic polymer flocculants by polymerizing two types of monomers for harvesting Chlorella vulgaris ( C. vulgaris) and Porphyridium purpureum ( P. purpureum ), which are freshwater and marine microalgae species, respectively.
- How do cationic polymers cause flocculation?
- In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation. High molecular weight polymer (i.e. very long chain of monomers) bridges destabilised microalgae flocs , , .
- What are the advantages of cationic polymer flocculants?
- The observed flocs stability is a major advantage of cationic polymer flocculants. Inorganic flocculants formed a foamy and powdery layer of flocculated biomass on the bottom of the flask in the experiment .
