Against the backdrop of global advocacy for green and low-carbon development, bio based materials have gradually become an important direction to replace traditional petrochemical materials. In recent years, glyceryl monostearate (GMS) has made new breakthroughs in the research and development of biobased materials due to its unique molecular structure and multifunctional properties, and is becoming an important raw material for promoting innovation in multifunctional materials.

Unique molecular structure endows multifunctional properties

Monostearic acid glycerides are monoester compounds formed by glycerol and stearic acid, possessing both hydrophilic and lipophilic structures, thus exhibiting significant amphiphilicity in materials science. This characteristic enables it to demonstrate the following advantages in different systems:

·Emulsification and dispersibility: GMS can improve the compatibility between components, enhance the uniformity and stability of materials in composite material formulation.

·Plasticization and Flexibility Adjustment: By regulating intermolecular forces, GMS can improve the flexibility and processability of biobased polymers.

·Renewable and environmentally friendly: GMS derived from vegetable oils has good renewability and conforms to the concepts of green chemistry and circular economy.

These characteristics make GMS not only a traditional emulsifier and food additive, but also an important support for the development of functional biobased materials.

Technological breakthroughs bring about application expansion

In the past, glycerol monostearate was mainly used in industry for food, cosmetics, and pharmaceutical excipients, with relatively limited application scope. With the advancement of materials science and processing technology, its potential in the field of biobased materials is gradually being released:

·Efficient compatibilization modification: Researchers have demonstrated excellent compatibilization effects of GMS in biodegradable polymers such as starch based and PLA through molecular design and interface regulation, improving mechanical properties and processing stability.

·Self assembling functional structure: By utilizing the amphiphilicity of GMS, self-assembled structures can be achieved at the nanoscale, providing ideas for the development of new membrane materials, drug delivery carriers, and multifunctional packaging materials.

·Green composite system: When combined with natural polymers such as chitosan and cellulose, GMS not only improves dispersibility, but also endows the material with moisturizing, antibacterial and other functions, expanding its application boundaries.

These breakthroughs provide solid technical support for the application of GMS in high-performance biobased materials.

New impetus for the research and development of multifunctional materials

Driven by sustainable development, the application of monoglycerides has moved from a single additive function to a multifunctional composite direction. For example:

1. Bio based packaging materials: By introducing GMS, packaging films have been significantly improved in flexibility, barrier properties, and antibacterial properties, providing better solutions for food preservation and safety.

2. Agricultural Degradable Film: Adding GMS to the formula of starch based film can improve the toughness and service life of the film material, while ensuring its biodegradability in the natural environment.

3. Medical and functional materials: In tissue engineering scaffolds or drug delivery materials, the biocompatibility and controllability of GMS provide a new path for the development of multifunctional composite materials.
