Abstract

In this article, the effect of different boron compounds additives on the thermal properties of wet spun polyacrylonitrile-co-vinyl acetate P(AN-VAc) fibers was investigated. Different boron compounds (boric acid (BA), borax (B), zinc borate (ZB) and their binary mixtures) were added to fiber spinning solutions in order to improve the thermal characteristics of P(AN-VAc) fibers. For all boron-added P(AN-VAc) fibers except the reference fiber sample, the proportions of (P(AN-VAc)) and boron compounds were kept constant at 90% and 10%, respectively. Boron-free fiber produced from 100% P(AN-VAc) was used as the reference fiber sample. While characteristic peaks of P(AN-VAc) were observed in the Fourier Transform Infra-Red (FTIR) spectra of all fibers produced with or without boron additives, peaks belonging to boron compounds were also observed in the FTIR spectra of boron-added fibers. The results obtained from the measurements of thermogravimetric analysis (TGA) and differential scanning calorimeter (DSC) indicated that there were significant improvements in the thermal resistance of boron-added P(AN-VAc) fibers compared to boron-free P(AN-VAc) fiber. As a result, it was determined that the most effective boron compounds on the thermal resistance of the P(AN-VAc) fibers were ZB, BA and B, respectively.

Özet

Bu makalede, farklı bor bileşikleri katkısının yaş çekim yöntemiyle üretilen poliakrilonitril-ko-vinil asetat P(AN-VAc) liflerinin termal özelliklerine etkisi araştırılmıştır. P(AN-VAc) liflerinin termal özelliklerini geliştirmek amacıyla, lif çekim çözeltilerine farklı bor bileşikleri (borik asit (BA), boraks (B), çinko borat (ZB) ve bunların ikili karışımları) ilave edilmiştir. Referans lif numunesi dışındaki tüm bor katkılı P(AN-VAc) lifleri için (P(AN-VAc)) ve bor bileşiklerinin katkı oranları sırasıyla %90 ve %10 olacak şekilde sabit tutulmuştur. %100 P(AN-VAc)'dan üretilen bor katkısız lifler referans lif numunesi olarak kullanılmıştır. Bor katkılı ve katkısız üretilen tüm liflerin Fourier Dönüşümlü İnfra-Red (FTIR) spektrumlarında P(AN-VAc)'a ait karakteristik pikler gözlemlenirken, bor bileşiği ilave edilen liflerin FTIR spektrumlarında ise ayrıca bor bileşiklerine ait pikler de gözlemlenmiştir. Termogravimetrik analiz (TGA) ve diferansiyel taramalı kalorimetre (DSC) ölçümlerinden elde edilen sonuçlar, bor katkılı P(AN-VAc) liflerinin ısıl direncinde bor katkısız P(AN-VAc) liflerine kıyasla önemli derecede iyileşmeler olduğunu göstermiştir. Sonuçta, P(AN-VAc) liflerinin ısıl direncine en etkili bor bileşiklerinin sırasıyla ZB, BA ve B olduğu tespit edilmiştir.
