4.34.6.1 Sol–Gel Application Forms Sol–gel materials can be prepared in a variety of different physical forms, including monoliths, crushed particles, microspheres, nanospheres, fibers, hydrogels, thin films and composites. Silica sol–gel monoliths or crushed particles were used as implantable or ...
stable chemical properties, and high mechanical strength. Silica gel desiccant has a very fine pore network structure. These pores can absorb water and retain water through its physical attraction. As a desiccant, it is widely used in aviation parts, computer devices, electronic products, and leath...
referred to as silica sol. These particles then aggregate to form a three-dimensional structure in a gel state maintaining a low refractive index of 1.46. During this process, growth conditions affecting the primary particles (sizes 3-30nm) are controlled to modify physical properties such as sur...
