Molecularly Imprinted Polymer sufficiently dissolves；Then the solution of conducting high polymers object is uniformly divided into two parts；
2. the portion in the conducting high polymers object solution for taking step (1) to prepare, diamond is added thereto, is surpassed
Sound mixing, supersonic frequency 20KHz guarantee that diamond is dispersed in solution；
3. using coaxial electrostatic spinning equipment, the conducting high polymers object solution 1. prepared using step is molten as cored structure
Then liquid carries out electrostatic spinning using the mixture of the diamond of step 2. and conducting high polymers object as shell structure solution, if
Determining spinning voltage is 18~22kV, and spinning distance is 5~15cm, and after spinning, obtained spinning is put into Muffle furnace, into
Row 180 DEG C of heat treatment in 2 hours, and then obtain diamond/fiber flexibility rubbing down tool of core shell structure.
The fiber that conduction high polymer is constituted is internal cored structure, is the flexible substrate of rubbing down tool, is microcosmic presentation three
Tie up the supporter of reticular structure；The diamond of half embedment is shell structure, plays the role of rubbing down to device, has Buddha's warrior attendant flexible
Stone/fiber can form being bonded for adaptivity with complex-curved, can become the polishing and grinding head of automation rubbing down machine, can also use
In the polishing of optics, electronic component.
The invention has the following advantages over the prior art:
(1) coaxial electrostatic spinning technology is used, diamond need to only be added to shell solution, save diamond dosage, simultaneously
Internal cored structure supports three-dimensional structure, maintains the flexibility of material.
(2) diamond/fiber flexible can form being bonded for adaptivity with complex-curved, can become automation rubbing down
The polishing and grinding head of machine, it is applied widely.
(3) preparation method is simple, and diamond has been fixed in rubbing down tool, reduces loss, has saved polishing cost.
