Polistiren(Ps) merupakan bahan polimer yang banyak digunakan untuk aplikasi sensor karena sifat viskoelastiknya. Permukaan lapisan Ps yang bersifat hidrofilik sangat diperlukan dalam aplikasi sensor untuk cairan. Permukaan yang bersifat hidrofilik dapat diperoleh dengan memodifikasi permukaan lapisan Ps menggunakan paparan sinar UV. Pada penelitian ini, waktu penyinaran UV yang digunakan adalah selama 30 menit, 60 menit, 90 menit, dan 120 menit. Variasi waktu penyinaran UV bertujuan untuk mengetahui perubahan sifat permukaan Ps. Hidrofilisitas polimer terkait dengan berat molekul dan polaritas polimer. Hal ini dapat dianalisis dengan menggunakan karakterisasi nilai sudut kontak lapisan Ps. Karakterisasi lapisan Ps setelah dipapari sinar UV dilakukan dengan menganalisis perubahan nilai sudut kontak. Berdasarkan percobaan yang telah dilakukan didapatkan bahwa semakin lama penyinaran UV menyebabkan semakin rendahnya nilai sudut kontak lapisan Ps. Nilai sudut kontak paling rendah yang dihasilkan adalah sebesar 55,801o ±0,0563o setelah dipapari sinar UV selama 120 menit.References
