ABSTRAK Shape Memory Polyurethane (SMPU) telah disintesis dari penambahan polyethylene glycol (PEG-6000) sebagai segmen lunak dan 4,4'-Methylenebis (Cyclohexyl isocyanate) (HMDI) sebagai segmen keras serta 1,1,1-Trimethylol propane (TMP) sebagai chain extender. SMPU lalu ditambahkan nanopartikel Fe3O4 berukuran 20-50 nm untuk meningkatkan sifat kemagnetan. Untuk mengkonfimasi bentuk ikatan antarmuka komposit SMPU digunakan FTIR (Fourier Transform Infrared Spectroscopy). FE-SEM digunakan untuk mengetahui interface dari filler dan matriks SMPU. Konfirmasi nilai kemagnetan menggunakan VSM (vibrating sampel magnetometer) dan pengujian tarik menggunakan microtensile menunjukkan bahwa penambahan Fe3O4 dengan persentase 11 wt% menghasilkan nilai kemagnetan dan sifat mekanik tertinggi. ABSTRACT Shape Memory Polyurethane (SMPU) has been synthesized by reacting polyethylene glycol (PEG-6000) as softsegment, 4,4'-Methylenebis (Cyclohexyl isocyanate) (HMDI) as hardsegment and 1,1,1-Trimethylol propane (TMP) as chain extender. SMPU was added by Fe3O4 as filler to provide magnetical property. Magnetite which had confirmed by Scanning Elctron Magnetic (SEM) have size 20-50 nm. Functional group was investigated by FTIR (Fourier Transform Infrared Spectroscopy). The magnetic behavior of the nanocomposites was observed by vibrating sample margnetometer (VSM). FE-SEM is used to acknowledge interface between filler and Shape Memory Polyurethane (SMPU) matrix. Mechanical properties tested by microtensile testing showed adding 11% Fe3O4 obtaining magnetic and nanocomposites SMPU resulted in improved materials with higher magnetical and mechanical properties. |
