Abstract

Komposit resin berbasis polimer merupakan salah satu material potensial untuk aplikasi wearable device karena sifat mekanik dan kemampuannya dicetak secara presisi menggunakan metode Digital Light Processing (DLP). Namun, tantangan utama dalam formulasi resin adalah ketidaksesuaian antara matriks dan filler yang dapat menyebabkan aglomerasi serta penurunan performa mekanik. Penelitian ini bertujuan untuk mengkaji pengaruh variasi konsentrasi filler Barium Titanate (BaTiO₃) dan dispersan BYK-111 terhadap sifat morfologi dan mekanik komposit tBA/BaTiO₃/CNT. Komposisi filler BaTiO₃ yang digunakan sebesar 20%, 25%, dan 30% berat, sedangkan konsentrasi BYK-111 divariasikan menjadi 10% dan 15% berat dari total resin. Pengujian yang dilakukan meliputi karakterisasi FTIR, SEM-EDX, uji sedimentasi, XRD, dan uji tarik sesuai standar ASTM D882. Hasil pengujian menunjukkan bahwa penambahan BYK-111 meningkatkan kestabilan dispersi partikel dengan mengurangi aglomerasi, ditunjukkan oleh penurunan nilai sedimentasi dan distribusi partikel yang lebih merata pada citra SEM. Namun, pada komposisi BaTiO₃ tinggi, kinerja BYK-111 menjadi kurang optimal karena adanya kompetisi ikatan antara dispersan dengan permukaan BaTiO₃ dan resin, sehingga tidak semua partikel terdispersi dengan baik. Nilai Young’s Modulus tertinggi sebesar 0,53854 GPa dicapai pada komposisi 20% BaTiO₃ dan 15% BYK-111, sedangkan UTS dan elongation at break terbaik juga diperoleh pada kondisi yang sama. Hasil ini menunjukkan bahwa pemilihan rasio BaTiO₃ dan BYK-111 yang tepat berperan penting dalam mengoptimalkan performa mekanik dan kestabilan morfologi resin komposit untuk aplikasi perangkat elektronik fleksibel

Polymer-based resin composites are promising materials for wearable device applications due to their mechanical properties and capability for precise fabrication using Digital Light Processing (DLP). However, a major challenge in resin formulation is the incompatibility between the matrix and filler, which can lead to agglomeration and decreased mechanical performance. This study aims to investigate the effect of varying concentrations of Barium Titanate (BaTiO₃) filler and BYK-111 dispersant on the morphological and mechanical properties of tBA/BaTiO₃/CNT composites. BaTiO₃ filler was used at 20%, 25%, and 30% by weight, while BYK-111 concentrations were varied at 10% and 15% by weight of the total resin. Characterizations conducted included FTIR, SEM-EDX, sedimentation tests, XRD, and tensile tests according to ASTM D882 standards. The results show that the addition of BYK-111 improves particle dispersion stability by reducing agglomeration, as evidenced by lower sedimentation values and more uniform particle distribution in SEM images. However, at higher BaTiO₃ concentrations, the effectiveness of BYK-111 decreases due to competitive bonding between the dispersant, BaTiO₃ surface, and the resin, resulting in less effective particle dispersion. The highest Young’s Modulus value of 0.53854 GPa was achieved with a composition of 20% BaTiO₃ and 15% BYK-111, which also yielded the best Ultimate Tensile Strength (UTS) and elongation at break. These findings highlight the importance of optimizing the BaTiO₃ and BYK-111 ratio to enhance the mechanical performance and morphological stability of resin composites for flexible electronic device applications.
