Production of a lightweight, flame retardant, sound absorption composition in the form of a phenol-aldehyde/polyurethane hybrid polymer foam of open cell structure and interconnected continuous porous architecture, by reacting 100 parts by weight phenolic resin, such as a resole resin of an aldehyde and a phenol, e.g. formaldehyde and phenol, having an aldehyde to phenol mole ratio greater than about 1:1; about 50-300 parts by weight aromatic or aliphatic polyisocyanate; about 0-100 parts by weight aliphatic group containing polyol, e.g. a polyether, polyester, polycaprolactone or polybutadiene polyol; and about 0-100 parts by weight filler; in the presence of a catalyst, e.g. a basic and/or metal salt catalyst in an amount of about 0.01-2 parts by weight, and a blowing agent, especially with all reactants but the polyisocyanate being premixed and then combined with the polyisocyanate for reaction in an open mold, e.g. with the resole resin having a pH of about 4.5-9.5, a solid content of about 50-98%, and a viscosity of not greater than about 100,000 cps at 25.degree. C., and optionally with a surfactant being included in the premixed reactants.
摘要:
A carbon nanocapsule-layered silicate hybrid is provided. Layered silicates (platelet-shaped) as a dispersant are mixed with carbon nanocapsules (sphere-shaped) by a physical process. The physically mixed hybrid exhibits a homogeneous dispersion phase due to the geometric shape inhomogeneity factor. Aggregation of carbon nanocapsules is thus avoided. The hybrid can be dispersed in a polar or non-polar solvent with a solid content of about 0.01-30 wt %.

An optical film with low or zero birefringence and a method for fabricating the same are provided. The optical film with low or zero birefringence includes a plurality of birefringence films, and the plurality of birefringence films is overlapped with the long axes perpendicular to each other. A sum of the refractive indices of the overlapped birefringence films in an x direction is equal to that in a y direction. The placement of the birefringence films in the optical film with low or zero birefringence can solve the problem that optical polymer cannot be applied to optical parts due to the birefringence of optical polymer.
