- Synthesize several superabsorbent polymers derived from synthetic and natural polymers. 
- Develop a liquid gel fire-extinguishing material from superabsorbent polymers. 
- Create a liquid gel fire-extinguishing material from a mixture of silica sol/cellulose hydrogel/phosphorus-containing compounds. 
- Establish a pilot-scale technology process for producing fire-extinguishing gel formulations.

-    Theoretical results:
• The project has successfully synthesized flame-retardant substances such as TiO2, Mg(OH)2, bentonite, APP, and nano-silica. These materials are cost-effective, with simple production methods that can be scaled up to pilot production.
• The project has systematically studied SAP materials derived from natural sources such as cellulose, alginate, and starch and has developed specific formulations for gels formed from these SAPs as follows:
• SAPNB has been synthesized by graft polymerization of acrylic acid and the crosslinker N, N'-methylene-bisacrylamide (MBA) combined with nano silica, nano bentonite, and nano Mg(OH)2. This material produces a gel formulation with excellent adhesion to material surfaces, impeding combustion. The SAPHP01 additive, with 30% SAPNB content, possesses a high hydrophilic-lipophilic balance (HLB=10), allowing rapid water absorption to form gel01 (comprising 5% SAPHP01 and 95% water), which is used as a material to prevent and extinguish fires. Experimental results indicate that gel01 can effectively extinguish Class I fires in under 300s , with fire resistance ranging from 1000 to 1300°C for 40s when applied in a 2 mm layer.
• The TS-AA-AMPS/APP material was synthesized from modified starch, AA, and AMPS, incorporating 3% APP by weight. The SAPHP02 additive, used to formulate gel02 containing 32% TS-AA-AMPS/APP, has an HLB value of 4.3, offering excellent water absorption and retention. Gel02, prepared from 3.5% SAPHP02 and 96.5% water, demonstrates exceptional adhesion to wooden surfaces (99%). Testing of the gel02 system shows a Class I fire extinguishment time of less than 300 seconds (262 seconds) and fire resistance of up to 45 seconds with a 2 mm gel coating.
• The fire-extinguishing gel can be supplied in either powder or viscous gel form and is easily deployable using standard firefighting equipment. The VH-GEL01 and VH-GEL02 systems have undergone systematic testing, from laboratory research to field trials at authorized firefighting agencies. These gels have proven effective in preventing and suppressing fires on wood, tarpaulins, and straw. Based on field experiments, the project developed and issued a technical specification (TCCS) for VH-GEL01 for fire prevention and suppression, serving as a foundation for establishing a national standard (TCVN) and enabling future research comparisons.
• The gels produced by this project are cost-effective, environmentally friendly, and utilize safe production methods, with scalability to large-scale manufacturing.
• The project enhances the scientific and technological capabilities of participating organizations, especially in the field of firefighting materials. It also contributes to research and development of new products using locally available, eco-friendly materials in Vietnam for fire prevention and national security purposes.
-    Applied results:
• New products have been developed with effective fire extinguishing capabilities that meet Vietnamese standards and are of comparable quality to international products, eliminating the need for imports and ensuring human and social safety. The resulting products are more cost-effective than imports and can be researched and produced domestically.
• The products are technically optimized, competitively priced (approximately 150,000 VND/liter), safe to produce, easily scalable, and completely non-toxic. They represent an economical and environmentally friendly solution with the potential to compete with international brands. This breakthrough lays the foundation for establishing TCVN standards in firefighting and opens up broader application and research opportunities in the future.

• Researched and developed core formulations to create two new-generation, environmentally friendly fire prevention/extinguishing gel systems to meet the needs of firefighting forces, households, agencies, and businesses.
•  The fire prevention/extinguishing gels developed in this project incorporate certain flame retardants and nanocomposites with high fire resistance, which are biodegradable and environmentally friendly. 
•  A new product (SAPHP01 and SAPHPP02) containing over 30% SAP has been successfully produced, which can be easily stored and formulated into a fire prevention/extinguishing gel, facilitating its use in firefighting operations. 
• The production line has been upgraded from a manual laboratory-scale process with low capacity to a pilot-scale gel formulation process with a capacity of 40 litres per batch, significantly exceeding the initial target of 15 litres per batch.a
