Abstract

Abstract This journal discusses the distribution of nanoparticles on the surface of the sample cloth and its crystal structure based on XRD results. This study consists of experiments and analysis of results using XRD, SEM, and FTIR. The results of this study concluded that the distribution of nanoparticles was less than optimal, which might be due to not using surfactants to modify the surface of the fabric, making it difficult for the nanoparticle clumps to spread and stick more evenly. Then it can be concluded that the nanoparticles formed are copper oxide (Cu2O) nanoparticles and have a crystal lattice type of a Primitive Cubic or simple cubic crystal lattice type overall, and sizes in the range of 25-130 nm. Keywords: Characterization, Copper Nanoparticles, Polypropylene Fabric

Abstract

Abstract In this research has conducted on the analysis of the material BSHF, the result of mixing BHF substitution with Sr on the composition of 7: 3 of material notation (B7S3)HF. The manufacturing process is done by wet milling with alkhohol mixed for 40 hours, followed by heating temperature 1200oC for 2 hours. During the milling process with an interval of 10 hours, the powder take off to measuring the diameter of the particle with PSA. Material that have been in the form of crystals and re-milling for 4 hours and then follow by the sonication for 6 hours to get nano size of B7S3HF material. Material in this nano size at 70 kN compaction pressure to get the bulk to be analyzed by XRD, Permagraph, and SEM. From these results identified the effect on inducted for the magnetic properties of the material B7S3HF. Keywords:, Mechanical Alloying, sonication, magnetic induction ,hysteresis

Abstract

Telah berhasil dilakukan sintesis nanopartikel perak yang dilapisi pada kain katun. Metode yang digunakan pada penelitian ini adalah metode reduksi kimia dengan menggunakan perak nitrat sebagai prekursor dan asam askorbat sebagai reduktor. Sampel hasil sintesis kemudian dikarakterisasi menggunakan X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) dan Scanning Electron Microscope (SEM). Tujuan penelitian ini untuk mengetahui struktur kristal yang terbentuk, ukuran partikel, morfologi permukaan kain katun, mengidentifikasi senyawa, dan daya serap adsorpsi nanopartikel perak terhadap kain katun. Berdasarkan hasil penelitian yang dilakukan, diperoleh hasil karakteristik struktur kristal berbentuk kubik, diperoleh hasil analisis ukuran partikel bervariasi dari 42.79 sampai 127.2 nm, hasil Fourier Transform Infrared (FTIR) menunjukkan bahwa nanopartikel Ag yang ada pada kain katun memiliki spektrum bilangan gelombang 798.2 cmˉ¹, 847.5 cmˉ¹, 1722.5 cmˉ¹, dan 1756.8 cmˉ¹. Hasil Scanning Electron Microscope (SEM) menunjukkan bahwa pada kain katun terdapat unsur perak (Ag) sebesar 75.53% Kata Kunci : Nanopartikel perak, katun, perendaman.
