The article introduces the progress in research on the 1CF target materials and target fabrication technology in China Academy of Engineering Physics. It involves mainly the following aspects： the target materials, capsule fabrication technology, ICF film targets, precise micro technology, and target parameter measurement. In the aspect of target materials, the perdeuterated polystyrene （D-PS） organic materials, the micro target doped materials and the metal nano-material and nanoclusters for the laser absorption and conversion of X ray have been prepared. We have studied exploringly the new organic aerogel hydrogen storage, the theory of metal small clusters and nano intermetallic compound materials. For the fabrication technology of target, we have fulfilled the fabrication of PS monolayered, double layered and threefold layered shell plastic microspheres. Using the polymeric coat by low temperature plasma method, we have built the technology of pure CH film deposited on microsphere surface and metal doped on CH films. For the study of Are filling in glass microsphere, we have used drilling holes on it by AFM and the gas-filling by particle radiation modified technology.
