Oct 23, 2018 · Hydrophobically associating polyampholytes can be applied to enhance the viscosity in high-salinity media by combining polyampholyte properties with hydrophobicity [212, 213]. Low charge quenched polyampholytes containing acrylamide (90 mol%), AMPSNa (3–7 mol%), MADQUAT (3–7 mol%), and N,N-dihexylacrylamide or N-(4-ethylphenyl)acrylamide (0 ...

Besides their high stability and long-lasting hydrophilicity in ambient and aq. environments for 60 days, the nanometric layers (48 ± 3 nm) of HA-MKM NPs on PDMS showed no adsorption of BSA and lysozyme and substantially lower adsorption of fibrinogen as revealed by a quartz crystal microbalance with dissipation (QCM-D).

Feb 01, 2022 · To reduce the impact of biofouling, antifouling coatings have been developed and applied to marine vessels since ancient times. Traditional antifouling coatings consist of chemically active compounds, such as silver , copper and tributyltin (TBT) .These coatings lack specificity, exhibit high toxicity to both fouling organisms and nontarget marine life, and lead to …

Mar 10, 2019 · The prosthesis was performed using PLACTIVE TM (1% antibacterial nanoparticles additive, Copper 3D, Santiago-Chile), which is a high-quality polylactic acid polymer. The main result of this research was to prove that the antibacterial 3D oriented filament can be effectively used for prostheses, and that their antibacterial properties after ...

Jan 21, 2019 · Zwitterionic hydrogels, as highly hydrated and soft materials, have been considered as promising materials for wound dressing, due to their unique antifouling and mechanical properties. While the viscoelasticity and softness of zwitterionic hydrogels are hypothetically essential for creating adaptive cellular niches, the underlying mechanically …

Procedure: A. Intrinsic viscosity determination by Ubbelhode viscometer: 1. Keep ready the solvent for this experiment: 0.05 M NaNO3 and 0.02% NaN3.Use previously prepared PAM solutions (Co = 4%, 8% or 12%) to form diluted solutions of concentration Ci such that C1 = 0.0010 g/cm3 C2 = 0.0015 g/cm3 C3 = 0.0020 g/cm3 C4 = 0.0025 g/cm3 The values of Ci need not be …

This was achieved by using a low-cost microvacuum pump and a single potential supply at a constant voltage. Both 12% linear polyacrylamide (LPA) with a high viscosity of 15000 cP and 2% hydroxyethylcellulose (HEC) with a low viscosity of 102 cP were chosen as the sieving materials to study the behavior and the versatility of the proposed method.

Polyacrylamide grafted starch (St-g-PAM) was made by a novel method of synthesis, involving combination of microwave radiation and a chemical free radical initiator (ceric ammonium nitrate) to initiate grafting reaction. This method (microwave assisted synthesis) is …

Apr 08, 2021 · Polyacrylamide gel can be used as a non-thrombin progranulation agent, raw materials for surgery, contact lenses, outer coating of microcapsules, and used to manufacture high-quality hemostatic plugs, sanitary napkins and diapers for children, etc. Polyacrylamide with a particle size of several hundred microns to several tens of microns can be ...

Because zwitterionic polyacrylamide contains cationic groups and anionic groups in the molecule, it has the characteristics of general cationic flocculants and exhibits more excellent performance. This type of flocculant can be used in a wide range of PH values, with higher water filtration and lower cake water content, and can also be used for ...
