We developed a method for in situ fabrication of f unctional material s in side the fiber by microwave selective heating . Th e method has three steps First, the raw material solution is absorbed to the fiber. Second , the fiber is immersed and pressurized in immiscible liqu ids with the raw material solution. Finally, the functional materials are in situ fabricated inside of the fiber by the microwave selective heating. As a model reaction, we fabricated silver nanoparticle in duced cotton fiber. The elemental silver was distributed inside of the fiber in a cross sectional distribution as confirmed by SEM EDS. The silver induced cotton has ability of the a nti bacterial functions an d launderability W e also fabricated zeolite particles inside porous PTFE fibers as another demonstration.
