“…Nowadays, photopolymerization of composites is used for different applications such as the curing of dental cements 32,33 and others. 34,35 The principal shortcoming of the photopolymerization process applied to composite formulations is the limited light penetration strongly reducing the potential depth of cure. However, the main advantages of composites are their high strength and relatively low weight.…”

“…As can be seen, CNTs have light absorption in UV region. To overcome this drawback, one can use higher UV light intensities and longer irradiation times [7,76]. Another approach to dominate this effect of CNTs.…”

This chapter covers the preparation and properties of ultraviolet (UV)-curable nanocomposite containing carbon nanotubes as fillers. UV-curing technology is of particular interest due to its unique properties such as rapid curing process and solvent-free formulation. Alongside with the advantages of utilizing this curing method, carbon nanotubes undergo benefits including high aspect ratio, high transparency, and good mechanical properties. Carbon nanotubes (CNTs) are hollow cylindrical shaped configuration; consist of one, two, or more walls with an interlayer of non-covalent van der Waals force acting among the carbon atoms of various walls. Besides influencing the UV curing process, the CNTs loaded UV-curable nanocomposites sustain modified surface, thermal, mechanical, physical, and conductive properties which are discussed in this chapter. The health and safety concerns of using these classes of nanocomposite are further discussed.

“…Nowadays, acrylic materials are widely present in various application fields and many commercial resins are available on the market. If these acrylic resins are currently used to elaborate photocured materials, they can also be mixed with (in)organic fillers to obtain composite materials for dental applications [1][2][3][4], paints [5,6], ceramics [7][8][9][10]. The main shortcoming of the photopolymerization process applied to composite formulations is the low depth of cure due to the limited light penetration resulting from scattering by fillers and filler-matrix interface.…”

A set of commercial (meth)acrylic resins was photopolymerized under identical irradiation conditions and evolution of their refractive index was monitored as a function of double bond conversion. Initial refractive index values ranged from 1.4445 to 1.5454 and then linearly increased with conversion as long as the material was not in the glassy state. This increase was related to an increase of the material density arising during polymerization. Final refractive index values ranged from 1.4804 to 1.5632. The knowledge of the refractive index and of its evolution during the photocuring is indispensable, in particularly to elaborate composite materials (polymer matrix + filler) with well controlled optical properties.
