| Abstract:Collagen fibers (CF) were extracted from domestic animal skins, which were the novel microwaves absorbent after chemical modification. The microwaves shielding paper was prepared using collagen fiber microwaves absorbent blended with plant fibers (KP bamboo pulp). The effect of dosage of collagen fiber microwaves absorbent on the shielding efficiency (SE) and strength of the shielding paper was investigated. Experimental results indicated that the shielding efficiency of plant fiber paper could be obviously improved after collagen fiber microwaves absorbent was added, and its SE values could be increased with the increase of the dosage of the absorbent. In the paper with basis weight of 90 g/m2, the SE reached at 35 dB when 60% （mass basis）of absorbent was added. Further investigation indicated that the strength of plant fiber paper was enhanced when the content of absorbent was not higher than 55%. Therefore, the collagen fiber can be used to produce shielding paper. |
