The present work focused on the design of drug delivery system (DDS) based on a pH-,saltand temperature sensitive superabsorbent hydrogel.The novel biopolymer-based superabsorbent hydrogels were prepared by grafting crosslinked poly(AA-co-BuMC) chains onto CMC backbones through a free radical polymerization method. the hydrogel,s structure was confirmed using FTIR spectroscopy. Results from sca...

Disposable hygienic products are classified as technical textile and used intensively in the field of medical textiles. As a product, sanitary napkin consists top sheet, an inner layer (Acquisition Distribution Layer (ADL) core Pulp/Superabsorbent mixture), back sheet. Nonwovens commonly production these components. The most important factors to consider new product design rapid absorption mens...

Gellan Gum (GG) was modified with N-vinyl Formamide (NVF) through PDP/Ag + redox system initiated graft copolymerization in a thermostatic water bath at 35°C under nitrogen atmosphere. The highest percentage of grafting (186%) and the lowest homopolymer content (22.2%) were achieved through a systematic optimization of the polymerization variables, including reaction time, temperature, and conc...

introduction water super absorbents are water absorbing natural or synthetic polymers (they may contain over 99% water). they have been defined as polymeric materials which exhibit the ability of swelling in water and retaining a significant fraction (> 20%) of water within their structure, without dissolving in water content. the applications of hydrogels are grown extensively. these materials...

in order to study the effect of irrigation interval, n fertilizer and superabsorbent on yield and qualitative traits of sesame (sesamum indicum l.), a split-split-plot experiment was coducted in a farm in khusf of birjand, iran in 2009 on the basis of a randomized complete block design. the main plot was devoted to irrigation interval at three levels of 6, 12 and 18 days, the sub-plot was devot...

Self-compacting concrete (SCC) is an innovative type of that does not require vibration for compaction; however, it needs attention in relation to the control thermally generated cracks, due hydration heat mainly during curing process pieces with large volume. In this study we investigated addition Superabsorbent Polymers (SAP) as internal elements self-compacting mortar (SCM), well its thermal...
