Abstract

Komposit PMMA/n-Z dengan variasi komposisi pengisi serbuk zirkon nanometrik (n-Z) telah berhasil disintesis. Pengisi n-Z disintesis dari pasir zirkon yang berasal dari pasir puya Kalimantan dengan metode wet milling. Serbuk zirkon murni didapatkan dari proses separasi magnetik, penggilingan, perendaman dengan HCl, dan pereaksian dengan NaOH. Serbuk zirkon murni kemudian digiling menggunakan planetary wet milling selama 15 jam dilanjutkan dengan anil sehingga diperoleh serbuk zirkon berukuran nanometrik (n-Z). Hasil analisis kualitatif XRD dan SEM menunjukkan terbentuknya pola difraksi fasa tunggal yang sesuai dengan referensi [No. CIF 90-0084]. Analisis kuantitatif XRD menunjukkan nilai parameter kisi n-Z semakin mengecil seiring proses penggilingan. Serbuk n-Z kemudian dicampurkan dengan PMMA sebagai pengisi komposit PMMA/n-Z dengan variasi komposisi 1 wt.%, 2,5 wt.%, dan 5 wt.%. Komposit PMMA/n-Z selanjutnya dianalisis menggunakan XRD, FTIR, SEM, DMA, dan UV-vis. Hasil karakterisasi XRD dan FTIR mengonfirmasi keberhasilan pembentukan komposit. Analisis kualitatif SEM menunjukkan bahwa komposit semakin kompak dengan bertambahnya jumlah pengisi. Analisis kuantitatif SEM-EDX menunjukkan tingkat kehomogenan komposit meningkat seiring penambahan pengisi. Pengujian DMA menunjukkan bahwa peningkatan komposisi pengisi menyebabkan peningkatan nilai modulus tarik komposit PMMA/n-Z. Berdasarkan hasil analisis UV-vis, komposit PMMA/n-Z berpotensi diaplikasikan dalam bidang proteksi material terhadap paparan sinar UV-B.

Poly(methyl methacrylate) (PMMA)-based composites with varying compositions of nanometric zircon (ZrSiO4) powder (n-Z) were successfully synthesized and their tensile moduli were analyzed. The n-Z filler was synthesized from zircon sand originating from Kalimantan using a wet milling method. Pure zircon powder was obtained through magnetic separation, milling, HCl soaking, and reaction with NaOH. The pure zircon powder was subsequently milled using planetary wet milling for 15 hours followed by annealing to obtain nanometric-sized zircon powder (n-Z). XRD and SEM qualitative analyses confirmed the formation of a single-phase diffraction pattern corresponding to reference [No. CIF 90-0084]. Quantitative XRD analysis showed that the lattice parameter of n-Z decreased with increasing milling duration. The n-Z powder was then mixed with PMMA to produce PMMA/n-Z composites containing 1 wt.%, 2.5 wt.%, and 5 wt.% filler. The composites were characterized using XRD, FTIR, SEM, DMA, and UV-vis spectroscopy. XRD and FTIR results confirmed the successful formation of the composites. Qualitative SEM observations indicated that the composites became more compact as the filler content increased. Quantitative SEM-EDX analysis showed improved composite homogeneity with increasing filler content, reflected by the decrease in filler dispersion index from 0.33 to 0.26 for the 1 wt.% and 5 wt.% composites, respectively. DMA analysis revealed that higher filler compositions resulted in higher tensile modulus values of the PMMA/n-Z composites. UV-vis characterization indicated that these composites have potential applications in protecting materials against UV-B light exposure.
