  1. Sodium polyacrylate is a chemical polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water. When dissolved in water, it forms a thick and transparent solution due to the ionic interactions of the molecules. Sodium polyacrylate has many favorable mechanical properties.

  2. Superabsorbent polymers are now commonly made from the polymerization of acrylic acid blended with sodium hydroxide in the presence of an initiator to form a poly-acrylic acid sodium salt (sometimes referred to as sodium polyacrylate). This polymer is the most common type of SAP made in the world today.

  3. L'aimantation d'un ferrofluide à saturation est égale, à la dilution près, à celle des matériaux qui le compose. Par exemple, un ferrofluide à base de magnétite, concentré à 15 %, possède une aimantation de 52,5 kA/m (kiloampères par mètre, 10 3 A/m) à saturation [5], [3].

  4. 聚丙烯酸鈉(英文:Sodium polyacrylate 或 acrylic sodium salt polymer),簡稱ASAP,又稱super-slurper(因為該物可以吸收質量比200到300倍的水分),是一種分子式為[-CH 2-CH(COONa)-]反覆的聚合物,經常用在消費者產品之中。丙烯酸聚合物通常都帶有陰性電荷。雖然這類高分子 ...
