Dynamics of Competitive Polymer Adsorption onto Planar Surfaces in Good
The adsorption involves an initially independent adsorption of the two polymer types followed by competitive adsorption. The competitive adsorption is characterized by a maximum of the adsorbed amount and a desorption of the polymer with the smallest surface affinity and a continued, but reduced, growth of the adsorbed amount of the polymer with the largest surface affinity.
Insights into the p-nitrophenol adsorption by amidoxime-modified poly
Due to its notable thermal stability and significant levels of mechanical strength, polyacrylonitrile (PAN) is employed in the adsorption process. 22 The PAN-based polymer was employed as an adsorbent due to the presence of the reactive cyano group along the adsorbent chains that can be chemically modified into active amidoxime groups to capture
COMPETITIVE ADSORPTION OF POLYMER AND PLASTICIZER INTO
'It is difficult to quantify the amount of plasticizer and biopolymer that resides itr or outside the clay gallery, but their quantification is very important as the polymer-plasticizer...
Impact of alternative materials to plasticized PVC infusion
Medical tubings in plasticized polyvinylchloride (PVC) are widely used for the infusion of medications but are known in some cases to cause content-container interactions (drug sorption and
Development of a Highly Efficient Environmentally Friendly Plasticizer
The new environmentally friendly plasticizer has good compatibility with PVC and high thermal stability. The effectiveness of the plasticizing action of adipate based on the glass-transition...
- Can MPs release toxic additives under different environmental conditions?
- Compared with single adsorption, the competitive adsorption of three PAEs increased the adsorption capacity of DEHP and decreased the adsorption capacity of dibutyl phthalate (DBP) and diisobutyl phthalate (DIBP). These findings help predict the potential of MPs to release toxic additives under different environmental conditions.
- What is Sciences Malaysian Polymer Journal?
- 1. Sciences Malaysian Polymer Journal is an open access journal published in English under the auspices of the Plastics Rubber Institute of Malaysia (PRIM). It presents up-to-date results of scientific research and new information in the field of polymer science and technology.
- Does competitive adsorption increase PAE capacity in MPs?
- Additionally, considering the total adsorption of ΣPAEs, competitive adsorption led to an increase the adsorption capacity of PAEs in MPs.
- Which polymer has the least water absorption?
- PE-S showed the least amount of water absorption, resulting in the least amount of microcracks in the polymer matrix due to PE swelling due to the strong adhesion between fibers and matrix (Gupta, 2018). Incorporating 30% glycerol into PE-S as a plasticizer proved but disturbed the film’s mechanical performance.
- Which polymer has the highest water absorption?
- PE-S-30AVgel displays the highest percentage of water absorption with 54.53%, followed by PE-S-30G (19.0%), PE-S-30G-1AVpow (3.08%), and PE-S (2.69%). PE-S-30AVgel has the highest water absorption because of micro gaps in the polymer matrix that allow water molecules to infiltrate until saturation.
- How to reduce adsorption of PCE in clays?
- Reduction in the number of active sites of clays by the addition of small molecular polymers as sacrificial agents can decrease the physical and chemical adsorption of PCEs. Introduction of functional groups into PCE can restrain its intercalation by clays. Apparently, more clays robust PCE superplasticizers can be achieved via molecular design.
