본 발명은 LBL 멀티레이어링 기술을 이용한 전도성 펄프섬유의 제조 방법 및 이를 이용한 전도성 종이에 관한 것이다. 본 발명은 반응조 내의 펄프섬유를 증류수로 희석하는 단계, 반응조 내의 염농도를 2∼15 mM로 조절하고 pH를 6∼10으로 조절한 후 양이온성 고분자 물질을 투입하여 펄프섬유의 표면에 양이온성 고분자 물질을 정전기적 흡착시키는 단계, 반응조 내의 증류수와 미흡착된 양이온성 고분자 물질을 배출시키고 증류수를 재투입하여 펄프섬유를 세척하는 단계, 반응조 내의 염농도를 2∼15 mM로 조절하고 pH를 2∼6으로 조절한 후 음이온성 전도성 고분자 물질을 투입하여 양이온성 고분자 물질의 표면에 음이온성 전도성 고분자 물질을 정전기적 흡착시키는 단계 및 반응조 내의 증류수와 미흡착된 음이온성 전도성 고분자 물질을 배출시키고 증류수를 재투입하여 펄프섬유를 세척하는 단계를 포함하는 LBL 멀티레이어링 기술을 이용한 전도성 펄프섬유의 제조방법을 제공한다. 상기 LBL 멀티레이어링 기술을 이용한 전도성 펄프섬유의 제조 방법 및 이를 이용하여 제조된 전도성 종이에 따르면, LbL 멀티레이어링 기술을 적용하여 음이온성을 띠는 펄프섬유 상에 양이온성 물질인 PEI와 음이온성 물질인 PEDOT-PSS 복합물을 번갈아 다층 흡착하는 것에 의해 상기 펄프섬유 상에 높은 전기전도도를 부여함과 동시에 기계적 성질인 인장 강도 또한 증가시킬 수 있는 이점이 있다.
