NOVELTY - Preparation of charged protective coating involves mixing conductive nanomaterial and aniline hydrochloride, adding three anti-paint diluent as organic phase additive solvent to prepare conductive nanomaterial mixed solution, and mixing existing spacecraft circuit board with three-proof paint diluents. USE - Preparation of charged protective coating in spacecraft circuit board (claimed). ADVANTAGE - The coating uses conductive nanomaterial, which plays a main role in discharging charge, and aniline hydrochloride conductive polymer material is a bond between conductive nanoparticle charge transfer discharge, which greatly increases the radiation induced conductivity of the coating. The low mass fraction can obtain transparent inner charged protective coating. According to the control requirement of conductive nanomaterial and aniline hydrochloric acid content ratio satisfy charged coating conductivity, the conductive nanomaterial is main conductive material, and aniline hydrochloric acid is additive conductive material. The coating is directly coated on the surface of the circuit board to obtain coating, can adjust the controllable resistance of the charged protective coating in the spacecraft circuit board, so that the charged protective coating in the spacecraft circuit board satisfy different from the electrostatic protection level requirement, adjusting the mass fraction of the conductive nanomaterial, the conductivity is increased along with the mass fraction of the conductive nanomaterial, which is increase the charge generation, composite and flow, and effectively reducing the charging field strength of the polymer material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for charged protective coating in spacecraft circuit board, which involves coating the charged protective coating on the spacecraft circuit board directly, or coating existing spacecraft circuit board on the spacecraft circuit board as layer (L1), and coating conductive nanomaterial mixed solution on the spacecraft circuit board as layer (L2).
