Abstract

Telah dilakukan penelitian dalam pembuatan lapisan tipis struktur tiga lapis dengan bahan Polystyrene 3% dan PMMA 2% pada substrat microscop slides dengan metode Spin Coating. Metode Spin Coating merupakan metode yang relatif mudah dilakukan dan mampu menghasilkan lapisan yang bagus. Proses Spin Coating tersebut dilakukan dengan variasi kecepatan pemutaran yaitu 1000 rpm. 1500 rpm dan 2000 rpm serta variasi waktu pemutaran yaitu 30 detik dan 60 detik. Hasil dari pelapisan dilakukan proses pemanasan menggunakan Hot Plate pada temperatur 90°C selama 10 menit. Pengaruh kecepatan putar berdampak pada ketebalan lapisan. Kecepatan 2000 rpm menghasilkan ketebalan yang lebih tipis dari kecepatan 1000 rpm dan 1500 rpm, karena semakin besar kecepatannya maka semakin banyak larutan yang terpencar keluar substrat sehingga ketebalannya menjadi lebih tipis. Lapisan tipis diamati dengan menggunakan mikroskop. Ketebalan lapisan tipis menurun seiring dengan bertambahnya kecepatan putar.

Observation for fabricating thin film multilayer using materials polymer Polystyrene 3 % and PMMA 2% into microscope slides substrate using Spin Coating method had been done. This method is easy and the result of thin film is good. The spin Coating process was done with rotary speed variation about 1000 rpm, 1500 rpm and 2000 rpm and the rotary time are 30 second and 60 second. Then the result of Coating is heated on Hot Plate, with temperature 90°C for 10 minute. The influence of speed is making an impact on the thickness of material. On 2000 rpm the thickness of Coating is thinner than 1500 rpm and 1000 rpm, because the quicker the rotary speed, the more solution is dispersed hence, the Coating is getting thinner. The thickness of thin film is observed by microscope. The thickness of thin film is dropping along with the raising of rotary speed.
