Several microfabrication methods for polymer-based CD microfluidic platforms are presented in this paper. For prototyping, both traditional CNC-machining and photolithography techniques were used. For mass production, mold inserts were made by CNC-machining of tool steel and LIGA-like processes such as UV photolithography, photolithography/electroplating, and photolithography/deep reactive ion etching...
Most conventional drug delivery systems are based on polymers or lipid vesicles. These chemically synthesized materials can be designed to be biocompatible and have good functionality, but they often lack well-defined properties, due to an inherent size and structure distribution resulting from chemical synthesis. On the other hand, micro-fabrication technology developed for microelectronic applications...
The rheological and morphological changes of a low shrink unsaturated polyester resin during thickening and curing were investigated. The behaviour of low profile additive (LPA) could be modified by adding a thermo-breakable functional group to its molecule. The thickening reaction of the modified LPA with MDI was much faster than that of LPA with MgO, and the viscosity was stable for 3 months....
Thermally breakable functional groups based on diketogulonic acid and salt formation between amine and carboxy groups were grafted onto the chains of unsaturated polyester (UP) molecules. These functional groups are stable at room temperature but can be broken at elevated temperatures. They can also react with isocyanates. The modified UP resin showed a fast viscosity rise during thickening and...
