1-decanoic acid와 tri-n-octylphosphine을 분산 안정제로서 사용하고, $NaBH_4$를 환원제로 사용하여 화학적 환원법으로 $AgNO_3$ 수용액으로부터 페이스트용 은 나노입자를 제조하였다. 은 나노입자의 생성, 은 나노입자의 형상 및 크기를 XRD, UV-vis, TEM 및 SEM으로 조사하였다. 합성된 은 나노입자로 페이스트를 제조하여 점도를 측정하였으며, PET 막에 코팅하여 제조된 은 박막의 표면저항을 조사하였다. $NaBH_4/AgNO_3$의 몰비는 1 : 5가 최적으로 나타났고, 최적의 몰비에서 10-200 nm의 잘 분산된 구형에 가까운 은 나노입자를 얻을 수 있었다. 최적의 조건에서 얻은 은 나노입자로 PET 막에 코팅하여 제조한 은 박막의 표면저항은 $41{\mu}{\Omega}/cm^2$의 낮은 값을 나타내었다.
