    Ultrathin AAO templates have self-organized honeycomb-like nanopores, and they are usually from several ten nanometers to several hundred nanometers in thickness.Ultrathin AAO templates have been widely used for fabrication of large-scale ordered arrays of surface nanostructures such as nanodots and nanoholes on the surface of substrates. Pores of ultrathin AAO template are uniform in diameter and highly ordered in a short-range. In addition, the material (Al2O3) is transparent in the near-infrared and visible spectrum, and is electrically insulated. Compared to other technology for making ord...

    AAO on Al substrate has honeycomb-like structure (shown in Fig. 1), composed with hexagon column of Al2O3, with a circular pore in the center. At the end of the pore, there is a half-sphere shape barrier layer oxide layer in contact with aluminum. The porous oxide film contains mutually parallel cylindrical pores extending from the barrier oxide layer to the film surface. AAO on Al substrate is the simplest product in AAO family, which can be fabricated into large area with a high success rate. Fig. 2 shows a typical picture of the AAO template.Fig. 1. Schematic of AAO on Al substrate.  F...

    Isotropic AAO templates, often referring to thicker AAO to be different from ultrathin AAO membrane, are widely used for a number of different fields. Topmembranes technology is specialized to make high quality isotropic AAO templates, with highly uniform and regular pore on both sides of the surfaces. The pores are arranged hexagonally within the single grains of the aluminum. The translucent nature of AAO is appealing to applications in biomedical field.Fig. 1. The structure diagram of isotropic AAO templates.Fig. 2. Typical SEM images of both sides of isotropic AAO template. Fig. 3. Ty...

Organic Membrane Product description


The ideal filter membrane should have uniform pore size, which can achieve precise control of the key processes, such as filtration, separation, purification and material preparation, so that it can be widely applied in the fields of high fine chemical industry, medical treatment, biopharmaceuticals, quality detection and water treatment. However, the existing membrane preparation technology, such as the processing method to track etched on behalf of and for the phase transformation and interfacial polymerization method for chemical synthesis technology, has disadvantages of complex technology, complex process, difficult to control, and can not achieve precise control of the pore size of the membrane, which directly affects the existing in the application inefficient or even invalid.  

The design of our membrane technology has achieved the controllable processing of the membrane. Based on the characteristics of micro and nano technology, the advanced microfiltration process developed by us is a very original micro nano processing technology, which truly realizes the precise control of the size, distribution and porosity of the filter membrane. The membrane materials of this technology to produce the aperture coefficient of standard deviation is less than 0.1% (excellent foreign brand aperture in general 15%-20% standard deviation), high porosity (effective porosity of up to 80%), and the vertical hole wall is smooth, can greatly improve the filtration efficiency, reduce maintenance cost. This innovative high - end filter membrane preparation technology is simple (only once), easy to produce in large scale, and is more green. Not only can substantially increase the efficiency in high fine chemical, medical, pharmaceutical, food, beverage, environmental monitoring and water treatment in the field of filtration, separation, purification and preparation of materials, and the various parameters and process control of these processes is more precise and predictable. It plays an important role in the preparation of nanomaterials. Compared with other membrane products at home and abroad, many key indicators of this product, such as pore size uniformity, porosity, through-hole rate, water flux, rejection rate, chemical physical stability, mechanical strength and so on, surpassed similar products.          

At present, the membrane technology based on modified micro and nano processing is mainly used for the development and application of customized products and technologies. Its applications include flexible electronic technology, ultracapacitor and other applications based on organic materials.
