Abstract

Epoksi berliang geronggang (PHE) telah dihasilkan melalui kaedah berasaskan air dan digunakan sebagai pengisi di dalam polimer bagi meningkatkan “sifat-sifat bersama” pengisi dalam komposit. PHE telah dihasilkan dengan membenarkan ketidaklengkapan cantuman titisan kecil epoksi dalam emulsi, yang mana disediakan melalui penghomogenan campuran epoksi, poliamida dan kalsium karbonat dalam air. Partikel epoksi ini selepas dimatangkan adalah poros, berongga dan berbentuk seperti sfera. Lubang pada partikel epoksi boleh diisi dengan matrik polimer untuk membentuk pengikatan antara partikel epoksi dan polimer. Pengikatan ini menjamin interaksi yang lebih baik dan pengigi ini berpontensi untuk digunakan sebagai pengisi penguat. Mekanisma pengikatan ini adalah suatu konsep yang baru dan “novel”. Porous hollow epoxy - PHE was produced by water based method and used as filler in polymer in order to improve the “collaborative properties” of filler in composites. The PHE was produced by allowing the incomplete coalescence of epoxy tiny droplets in emulsion, which was prepared by homogenizing the mixture of epoxy, polyamide and calcium carbonate in water medium. These epoxy particles after cured are porous, hollow and spherical. The holes on epoxy particle could be filled by the polymer matrix to form interlocking between epoxy particle and polymer. The interlocking should be promising better interaction and has potential to be used as reinforcing fillers. This interlocking mechanism is a new and novel concept.
