WebFeb 1, 2024 · As depicted in Table 3, raw PBT films have a quite high surface energy (38.7 mN/m), which is in agreement with the literature [17]. Conversely, PBT/OTESi samples surfaces possess much lower surface energy, even at low concentration of n-octyltriethoxysilane. For films with 1 wt. % of OTESi, γ s is equal to 24 mN/m.

WebMar 19, 2012 · Surface tension, a measurement of surface energy, is expressed in “dynes/cm” (or mN/m SI units). The higher the surface energy of the solid substrate relative to the surface tension of a liquid (water, printing inks, adhesives/encapsulation, coatings, etc.), the better will be its “wettability,” and the smaller will be the contact angle. Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries. It is a thermoplastic (semi-)crystalline polymer, and a type of polyester.
