Superabsorbent Polymers and Superabsorbent Polymer Composites
This article briefly describes the general aspects and cross-linking polymerization of superabsorbent polymers (SAPs) and superabsorbent polymer composites (SAPCs). Research and development of SAPs has become very active after the Northern Region Laboratory of the United States Department of Agriculture invented the first SAP, used as a soil conditioner. Based on the advancements in organic/ino...
متن کاملEffect of Superabsorbent Polymer on the Properties of Concrete
Incorporating superabsorbent polymer (SAP), which has the abilities of absorption and desorption in concrete can achieve the effect of internal curing. The influences of the volume, particle size and ways of entrained water of SAP on the workability, compressive strength, shrinkage, carbonation resistance and chloride penetration resistance of concrete were analyzed through the macroscopic and ...
متن کاملA superabsorbent polymer-containing wound dressing efficiently sequesters MMPs and inhibits collagenase activity in vitro
Superabsorbent polymer (SAP)-containing wound dressings present a valuable and unique category of wound management products. An in vitro approach was used to assess the effects of a new SAP dressing in treatment of non-healing wounds. It was shown that the SAP dressing possesses a significant binding capacity for MMP-2 and MMP-9 in vitro (P\0.001). The inclusion of the bound proteases was so st...
متن کاملPreparation of Biodegradable Flax Shive Cellulose-based Superabsorbent Polymer under Microwave Irradiation
Superabsorbent polymer was prepared by graft polymerization of acrylic acid onto the chain of cellulose from flax shive by using potassium persulfate (KPS) as an initiator and N,N-methylenebisacrylamide (MBA) as a crosslinker under microwave irradiation. SEM photographs were also studied for more information about the shive, cellulose from shive, and the superabsorbent polymer. The structure of...
متن کاملMultilayering of superabsorbent polymer dressings has no place in wound care.
This article is reprinted from the British Journal of Community Nursing, Vol 20, No 9, Community Wound Care September 2015 Dear Editor, In spite of many years of research and teaching, I have come to realise that some clinical practices are difficult to eradicate. One particular practice is the use of multilayered combinations of wound dressings often made up of components with very different f...
