So macromole is easily formed intermolecular and intramolecular hydrogen bond when being blended, and when being used for making membrane material, can make the formation of intermingling material
Membrane structure more stable.Gamma-polyglutamic acid-(γ-PGA) is the homopolymer of glutamic acid, is a kind of water soluble polymer, by D-
Glutamic acid or Pidolidone form, by alpha-amido and γ-carboxyl, the anionic polymer that γ-amido link is combined into, and have
The feature features such as good biocompatibility, good water solubility, degradable, edible, film property, as the life of a kind of new green environment protection
Thing material receives much concern, but readily soluble because meeting water, and certain degree limits its application.Micro-nano bubble refers to that diameter is between micron
Bubble (bubble of a diameter of 10-50um in water body) and nano bubble (a diameter of bubble less than 200nm in water body) it
Between bubble, have big specific surface area, can in water body the time of staying long, and micro-nano bubble is when shrinking, it is possible to
Producing substantial amounts of hydroxyl radical free radical, these substantial amounts of hydroxyl radical free radicals can attract the hydrogen in arghan element to a certain extent
Key, plays equivalent acidifying alkalization and destroys the effect that hydrogen bond is identical, the nanorize promoting arghan is improved its chemical reaction
Activity has certain facilitation.
The fibrous membrane that arghan based on modified gamma-polyglutamic acid-and high chemical reactivity combines is to improving Fructus Ananadis comosi
Comprehensive utilization and the abundant packaging film kind of leaf are significant.
