ABSTRAK

Penambahan kandungan pengisi polimer komposit dapat meningkatkan kekonduksian elektrik dan terma yang baik, serta mempunyai kekuatan tegangan dan modulus yang tinggi telah memperluaskan aplikasi dalam industri peranti elektronik. Walau bagaimanapun, penambahan kandungan pengisi yang kurang daripada 20 bt.% akan mengakibatkan ketidaksempurnaan dalam penyebaran serta terdapat gumpalan pengisi ke dalam komposit. Ulasan kajian ini adalah untuk mengenal pasti pengaruh penambahan kandungan pengisi bagi bahan konduktif polimer komposit menggunakan percetakan 3D terhadap sifat elektrik, terma dan mekanikal. Ulasan ini merangkumi penggunaan bahan konduktif polimer komposit yang dibentuk melalui kaedah Pemodelan Pemendapan Bersatu (FDM) yang merupakan salah satu daripada percetakan 3D. Proses percetakan 3D yang dilapisi oleh lapisan demi lapisan akan menghasilkan struktur objek yang kompleks serta proses pembuatan yang cepat telah memberi sumbangan kepada penghasilan konduktif polimer komposit. Kekonduksian elektrik dapat ditingkatkan dengan penambahan kandungan pengisi sehingga 50 bt.%. Selain itu, penambahan kandungan pengisi yang dapat menawarkan permukaan yang lebih berkesan antara permukaan pengisi dan matriks telah meningkatkan suhu penghabluran (T_c) dan suhu puncak penghabluran (T_p) dalam sifat terma serta nilai kekuatan tegangan dan modulus dalam sifat mekanik. Penambahan kandungan pengisi polimer komposit sehingga 50 bt.% dapat meningkatkan kesesuaian bahan untuk digunakan pada peranti elektronik.

Kata kunci: Polimer komposit; pemodelan pemendapan bersepadu; sifat mekanikal; sifat terma

ABSTRACT

The addition of filler content into polymer composite can improve electrical and thermal conductivity, while the resulting high tensile strength and modulus values have expanded its application in the electronic device industry. However, the addition of a filler less than 20 wt.% resulted in imperfections in the dispersion and agglomeration of filler within the composite. The aim of this study was to identify the influence of the addition of filler content into composite polymer conductive materials using 3D printing to determine the electrical, thermal, and mechanical properties. The scope of this study covers the use of composite polymer materials using Fused Deposition Modeling (FDM) method in 3D printing. The layer-by-layer element of the 3D printing process produces complex object structures and its rapid manufacturing processes contributes significantly to the production of conductive polymer composite. The study found that electrical conductivity can be improved with the addition of filler content. In addition, the addition of filler content offers a more effective surface between the filler surface and the matrix increased the crystallisation temperature (T_c) and crystallisation peak temperature (T_p) in terms of the thermal properties, as well as the tensile strength and modulus values ​​in terms of the mechanical properties. The approach provided in this review study was that the addition of filler content of up to 50 wt.% in polymer composite can improve the suitability of the material to be used in electronic devices.

Keywords: Conductive polymer composites; filler content; 3D printing
