All the bio-mimicked PMMA sheets show high optical haze ratio (up to 80%), while the transmittance varies depending on the morphologies.
The experimental results of transmittance and optical haze ratio are well consistent with the expectation.
Most bionic PMMA sheets have enhanced optical haze ratio ranging from 55-85%, while the hydrophobic properties are of great difference (see Fig.
Other fascinating properties of CNFs paper are ultrahigh transparency and adjustable optical haze. The regular paper is nontransparent, but the CNFs paper can be transparent when it is fabricated with nanofibers.
The optical haze and transmittance of transparent paper can be tuned by the porosity and the size of CNFs.
The maximum transparency of regular substrates is high about 90%, but its optical haze is very low (<20%), while CNFs paper has not only ultrahigh optical transparency (-96%), but also ultrahigh optical haze (-60%).
We blended various SEBS or SEPS together with Topas to vary the effective styrene content and the optical haze was measured.
The initial results with no compatibilizer showed that it is possible to obtain a Notched Izod of 80 J/m with an associated optical haze of 22% in a standard thickness of 3.2 mm (1/8 in).
It is also found that the addition of an index matched styrene-ethylene-butylene-styrene (SEBS) copolymer as a compatibilizer to the SBS elastomer is beneficial in increasing the toughness and lowering the optical haze. Finally, light scattering calculations are presented based on the Rayleigh Debye model to calculate the optical haze and transmission of these blends.
As can be seen, the TCO film slightly reduces the optical haze of the structure (by ~10%) and leads to the emergence of interference fringes.
The scattering properties of a number of differently textured surfaces have been studied in the literature, and the optical haze value has been widely used as a parameter to evaluate the scattering of light within thin-film structures [3, 7, 8].
Richter's Strip paintings allow for just such a self-reflexive opening up because their static optical haze
locates the viewer perpetually at the moment just before spectacle--rendered as the optical bombardment that we expect to ensue, but which the paintings always hold at bay--closes down our subjectivity.
