In a method for preparing ultra-thin films of carbon-containing materials, particularly thin films of polymer materials. Films with a thickness of 0.5 νm or less are formed by deposition of the materials from a liquid phase onto a solid surface. The deposition takes place in an enclosure where the materials also are subjected to a post-deposition processing. The total humidity content in the enclosure shall be maintained at a level corresponding to a relative humidity of less than 50% in a volume of air equal to the volume of enclosure by excluding and/or removing water and water vapour from the materials and/or the atmosphere in the enclosure.

The present invention discloses a generic method for producing void and gas occlusion free materials, as well as apparatuses (30) for batch and continuous production of same. This generic method can be utilized in the production of a wide variety of polymeric compounds and composites and specifically encompasses the two ends of the polymeric spectrum, that is, polymer concretes on the one hand, and fiber-reinforced polymer composites on the other. The composite materials of the present invention are characterized by visual count as being void and gas occlusion free to the level of 1 micron at 1250x magnification. Concomitantly, the invention produces useful polymer concrete materials which exhibit substantially improved integrity for easy machining at high speeds and high dielectric and mechanical strength, as compared with composite materials produced by conventional methods. Thus, one particular application for the materials of the present invention is the class of high voltage electrical insulating materials and insulators (80) where presence of voids, or gas occlusion flaws, may have deleterious effects, leading to their early failure.

In a process for manufacturing a three-dimensional object, the object is manufactured layer after layer. Each layer made of an electromagnetic radiation-hardenable material is applied, then radiation-hardened at spots corresponding to the object. Because of long heating and cooling times in the device used for manufacturing such objects, this manufacturing process is strongly delayed. In order to solve this problem, an area of the material which surrounds the object in each layer is irradiated, thus hardened, forming a containment wall (26) for the material (21).

摘要:
The purpose is to provide a method for producing an acicular body that enables filling of a material liquid to the tip ends of protrusions, and a device for producing the same. There is provided a method for producing an acicular body having a support base, and acicular protrusions on a surface of the support base. The method is characterized in that the method includes a supplying step of supplying an acicular body-forming liquid, in which an acicular body-forming material is dissolved or dispersed in a solvent, to an intaglio plate having recesses corresponding to the respective protrusions, a drying step of drying the acicular body-forming liquid in the intaglio plate to form an acicular body, and a peeling step of peeling the acicular body from the intaglio plate. The method is also characterized in that the supplying step is performed under a pressure environment of not more than 0.05 MPa, and the drying step is performed under a pressure environment higher than the pressure environment at the supplying step.
