synthesis of acrylamide-co-(itaconic acid) superabsorbent polymers and associated silica superabsorbent polymer composites. - super absorbent polymer cost
High Water Absorption Polymer (SAPs)
And related SAP composites (SAPCs)
There has been a lot of interest since the beginning of 1970.
During this period, Finda and others.
The grafting co-polymerization of vinyl acrylic or acrylic with starch and other polysaccharides was studied, and these products can absorb several hundred to several thousand times of weight in water, and also has the absorption capacity under pressure, also known as load (AUL)
Therefore, the name "high absorbent polymer" is adopted.
The research and development of SAPs is mainly concentrated in the usually high areas.
Water absorption performance and application.
In fact, more than 80% of SAPs have found a wide range of commercial applications in personal care products such as baby diapers 
Women's hygiene and incontinence3].
Not only that, through such research and development, many new applications have been studied, leading to successful applications in the new field of SAPsin, such as enzyme fixation [4, 5],bio-
Preparation of adsorption agents in chromatography 
Materials for agricultural film and fertilizer [7, 8]
Matrix used to control the release device 
Bioactive scaffold for bone engineering11], bio-separation 
Water retention in soil [13,14]
SAPCs as sealing material15]
Debris flow control, artificial snow [16, 17]
, Gel actuator 
And fire .
The design of the super absorbent is characterized by high expansion capacity, high expansion capacity and greater strength of the expanded gel.
Most of the super-absorbed bodies only include the first mentioned feature, I . E. e.
However, few studies have focused on the improvement of absorption rate and gel strength.
Absorption particles are usually reinforced by surface cross-linking .
Traditionally, inorganic components are used as filling materials to improve material performance and reduce product costs.
Addition of inorganic powder (usually
