AP08956439 "Development of innovative water-saving technologies using new biopolymer moisture sorbents for arid climatic zones"
Relevance
The authors of the Project propose to develop methods for obtaining polymer composites based on natural gels and fillers, which will allow accumulating and retaining moisture for a long time, gradually giving it to plants. Polyethyleneimine, agar-agar, chitosan and others will be used as synthetic and natural polymers, and bentonite clay as a natural silicate filler. Improving the water and physical properties of the soil will increase the germination of seeds, increase the intensity of plant development, their resistance to moisture deficiency and drought, lead to an increase in yield and prevent the fertile part of the soil from being washed away and moisture seeping into deeper layers of the soil. Thus, superabsorbents will reduce the costs associated with caring for plants, increase the survival of growing crops, and also provide plants with various types of additives that stimulate their best growth and development..
Objective of the project
Development of new highly swelling network polymer-silicate composites based on biocompatible synthetic and natural polymers with water-retaining properties for structuring soils in arid climatic zones.
The expected results of the project are
1) The main building blocks for creating new polymer composites with desired properties will be identified;
2) Optimal conditions for the synthesis of new moisture sorbents will be identified;
3) EPS and polymer-silicate composites with improved physical and mechanical properties will be created;
4) The composition and structure of new polymeric materials will be established;
5) Swelling limits of new polymeric materials will be determined;
6) The stability of the moisture-retaining action of new polymeric materials for a long time with repeated use will be revealed.;
7) The effect of polymer systems on the accumulation of moisture in soil under laboratory conditions will be established.
Results achieved
New polymer composites based on natural and synthetic gels and fillers have been obtained. Polycarboxylic acids, agar-agar, chitosan were used as synthetic and natural polymers, and bentonite clay was used as a natural silicate filler. It is expected that the resulting superabsorbents will reduce plant care costs, increase the survival of growing crops, and provide plants with various types of additives..
