High water vapor permeabilityA paper-based packaging material with improved air barrier and water vapor permeability (WVP) properties was synthesized based on layer-by-layer assembly consisted of poly(ethylenimine) (PEI)/graphene oxide (GO) on a filter paper substrate. The effect of the pH of ...
Clays and water-soluble polymeric materials, such as xanthan gum, carboxymethyl cellulose, and modified starch, are often added to WBDFs. Wherever the rheology and filtration properties at high-temperature conditions are needed, polymer-based drilling fluids are frequently preferred. The dispersion of ...
These include adhesives made from various biopolymers, such as cellulose, starch, and latex7. However, such adhesives remain highly flawed substitutes for traditional adhesives, as studies on such adhesives have reported poor bonding strength, poor water resistance, longer production times, and a ...
Suspension-based LDMs as antimicrobial agents An effective and common method of utilising the antimicrobial properties of LDMs are as suspension-based approaches. LDMs can be suspended within a range of liquid medium and allow for the free movement of LDMs along with providing a possible environment...
Cellulose-Derived Carbon Dots for Inner Filter Effect-Based Selective Sensing of Ofloxacin Antibiotics A two-step viable synthetic approach for quick and energy-efficient acid-based charring is described here to fabricate self-passivated fluorescent water-so...

New chemical-physical properties of water after iterative procedure using hydrophilic polymers: The case of paper filter It is taken for granted that paper filters (inert cellulose filters) do not affect water. However, our experiments show that after such filters repeatedly ... Elia, VittorioNapoli...
CHARACTERIZATION AND OPTICAL STUDIES OF ION BEAM-IRRADIATED CA/PANI COMPOSITE MATERIALS In the present research, cellulose acetate (CA) and polyaniline (PANI) were combined to form CA/PANI films using the solution-casting method. This research... HAIFA A. AL-YOUSEF,B. M. ALOTAIBI,A. ATTA,....
Hydroxypropylmethylcellulose HPMC is white or almost white fibrous or granular powder, which is an odorless and environmentally friendly material. HPMC is almost insoluble in absolute ethanol, ether and acetone. It disperses and dissolves quickly in cold water. The aqueous ...
Water used as a continuous phase and defoamer to inhibit the form of foams. Sodium carbonate function is to keep the calcium concentration within the acceptable range, and Xanthan gum polymer (XC-polymer) used as a viscosifier. Starch (i.e., potato type) and polyanionic cellulose (PAC) ...
All of these applications depend on controlling rates of ion and water transport across polymer membranes. Practical membrane-based desalination became possible with the development of asymmetric cellulose acetate (CA) membranes produced via nonsolvent-induced phase separation [63], [64]. While cellulose...
