Glass bubbles etched with tunable sizes of through-holes, also known as porous glass microspheres, are innovative materials with a range of potential applications. These structures are typically created through a process called sol-gel synthesis followed by selective etching. Here’s a breakdown of the concept and its applications:


  1. Sol-Gel Synthesis: The process begins with the creation of a sol-gel material, where a precursor solution containing metal alkoxides is polymerized to form a gel-like substance. This gel can then be shaped into microspheres using techniques like droplet formation.
  2. Selective Etching: After forming the microspheres, a selective etching process is applied to remove certain components from the gel structure. In the case of glass microspheres, the aim is to create through-holes or pores within the microspheres. This is achieved by carefully controlling the etching conditions, such as the type and concentration of etchant used, and the duration of etching.

1. Repair composite materials (resin putty)
The typical application of composite materials for repair is to add hollow glass microspheres into the resin to replace some fillers such as calcium carbonate and talc powder to make various types of putty. It has the advantages of light weight, strong adhesion, easy foaming, low shrinkage, and particularly significantly improved processing performance such as sanding and polishing. For hollow microspheres, dust is a problem. Interestingly, during post-processing, such as polishing, the damage to the hollow microspheres results in dust with the same density as glass, so that it does not float in the air and easily land on the ground. This will greatly reduce the disadvantage of high dust content in the air. This type of putty is widely used in repair operations of fiberglass products, automobiles, ships, machine tools, etc. It should be noted that the diameter of hollow glass microspheres should not be too large to prevent excessive pinholes after polishing, and a more ideal grading should be selected.

When the foam density is 0.66g/cm3, the static pressure strength is 1136kg/cm2. When manufacturing lightweight GRP core materials, it is precisely the use of hollow glass microspheres that solves the technical problem. Compared with conventional fiberglass, the use of this core material greatly improves the stiffness of the product and reduces weight. The thickness of the core material is selected based on the stiffness. The density of the core material is 0.57g/cm3~0.67g/cm3, and the compressive strength is 284kg/cm2~426kg/cm2. Widely used in various industrial products, such as sandwich composite panels for vehicles, ships, buildings, sports equipment, models, deep water floats, etc.
3. Polyester furniture
Polyester furniture is another application field of hollow glass microspheres, mainly aimed at reducing their density. For example, it can achieve a density of 0.9g/cm3 for mixtures, 1.09g/cm3 for perlite and 1.46g/cm3 for calcium carbonate. At the same time, it also improves processing performance such as sanding and polishing, saving around 50% of working hours. As the proportion of hollow glass microspheres increases, their stiffness also significantly increases.

The epoxy/glass bead synthetic foam has been successfully applied to the rudder in the United States. The foam plastic block is used as the core material of the rudder and the surface layer is glass fiber reinforced plastic. Compared with polyester, epoxy can significantly increase its strength while reducing weight. The data measured in the laboratory indicates that the ship rudder made of this material can withstand a bending load of up to 2500kg, which is three times the strength of engineering plastic ABS. In Germany, foam plastic blocks composed of polyimide resin and hollow glass beads are also used to make rudder, which is used on a 12.5m long, 55kg sailboat.
