CAS 160185-24-0 | Methacryl POSS Cage Mixture

Introduction and application of CAS 160185-24-0 | Methacryl POSS cage mixture

Specification:

Introduce:

Polyhedral oligomeric silsesquioxane (POS) is a new type of organic-inorganic hybrid material developed in recent years. POSS is a type of silane compound with the simplified structural formula (RSiO1.5)n. It is composed of an internal inorganic silicon oxygen core and a peripheral (covalently bonded) organic group. It is a true organic-inorganic hybrid structure. of nanomaterials. Its structure can also be freely controlled. When n is equal to 8, 10 and 12, the POSS molecular structures formed are different; it can be synthesized by hydrolysis polycondensation method, corner capping method, functional group derivatization method and other methods.

Features:

(1) Intramolecular hybrid structure

The POSS molecule itself is an organic-inorganic intramolecular hybrid system at the molecular level. This structure not only combines the respective advantages of organic and inorganic components, but also

The synergistic effect of the two produces new performance.

(2) Nano size effect.

POSS itself is a compound with nanometer dimensions. In its hexahedral structure, it can obtain small size effects and exhibit special thermal, optical, magnetic and acoustic properties.

quality.

(3) Structural designability

The Si atoms located at the top corners can be equipped with various reactive or non-reactive groups through chemical reactions to impart reactivity and functionality, thereby forming the required differences.

A capable POSS monomer.

(4)Good solubility

In general, most POSS monomers are soluble in common organic solvents, such as tetrahydrofuran, toluene and chloroform, and some are soluble in aqueous solutions.

(5) High thermal stability and structural stability

POSS has good thermal stability. The structure of its inorganic silicon-oxygen skeleton makes it still stable at high temperatures.

Use:

POSS's special cage structure and organic-inorganic hybrid system are mainly used for chemical modification/doping modification of other materials to improve raw material properties, such as improving heat resistance, improving mechanical strength, enhancing breathability, etc., and can also be used for multiple functions change.

(1)Heat-resistant and flame-retardant materials

POSS can be used alone as a flame retardant additive to modify composite materials to improve the flame retardant properties of the material, but it is more commonly used in combination with other flame retardants to achieve better flame retardant effects.

(2)Coating additives

Used as additives and cross-linking agents in coatings and coatings to improve the abrasion resistance, flame retardancy, mechanical properties, HDT value and air permeability of the material, and reduce the viscosity and conductivity of the material;

(3)Hydrophobic materials

One is to use the active sites of POSS itself and different monomers to synthesize low surface energy polymers containing POSS, and achieve hydrophobic modification of the surface by spraying; the other is to directly anchor POSS molecules on the polymer through thiol-ene click reactions. The surface of the substrate is used to improve the roughness of the surface and give it hydrophobic properties.

(4) Leather tanning agent

Introducing POSS into the leather nanocomposite tanning agent can not only effectively avoid the agglomeration of nanoparticles, but also the multi-side chain structure is conducive to forming multi-point combinations with collagen fibers, thereby achieving good tanning properties.

(5)Functional materials

Shape memory material: POSS is grafted and modified into a polyurethane main chain in a "hanging" manner to create a POSS modified polyurethane material, which has a shape memory function.

Catalyst: Utilizing the molecular sieve-like nanopore structure of POSS and combining it with different organic groups, it has important application value in gas adsorption and catalysis.

Classification:

Alpha's POSS products can be divided into powder and liquid:

Powders include trisilanol phenyl POSS, trisilanol isobutyl POSS, etc.;

Liquids include glycidyl POSS, epoxycyclohexyl POSS and other products.

POSS can also be searched by group: The following are the group types of POSS, which can be queried as needed:

Reactivity: hydroxyl, carboxyl, epoxy, styryl, vinyl, amino, olefinic, allyl, silane, silanol, etc.

Inert: cyclopentyl, cyclohexyl, isobutyl, ethyl, etc.

Hydrophilicity: hydroxyl group, carboxylic acid group, aldehyde group, sulfonic acid group, sulfate group, phosphate group, amino group, etc. Lipophilicity: alkyl, phenyl, cycloalkyl, hydrocarbyl, etc.
