Abstract

Partially phosphorylated polyvinyl alcohol (PPVA) with aluminum phosphate (ALPO4) composites was synthesized by solution casting technique to produce (PPVA)100−y − (ALPO4)y (y = 0, 1, and 2). The surface structure and thermal properties of the films were characterized using Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA). The results showed that the films have higher thermal stability with strong bonding between PPVA and ALPO4.

Highlights

The development of new polymer-inorganic composite materials has garnered much interest over the years due to their unique microstructures and physical and chemical properties, which are markedly different from other materials
The Fourier transform infrared (FTIR) results reveal that the maximum bonding between Polyvinyl alcohol (PVA) and phosphoric acids (PA) occurs in the F3 film
The phosphorylated poly(vinyl alcohol) (PPVA)-ALPO4 composite film exhibits enhanced thermal properties compared to PPVA and PVA films

Summary

Introduction

The development of new polymer-inorganic composite materials has garnered much interest over the years due to their unique microstructures and physical and chemical properties, which are markedly different from other materials. The phosphorylation of PVA with phosphoric acid (PA) in producing partially phosphorylated poly(vinyl alcohol) (PPVA) has attracted considerable interest in the applications such as fire-retardant materials [3,4,5,6,7,8], electrolyte [2, 9,10,11,12], membranes [13,14,15], metal chelating [16,17,18], paper making [19], sensors [20,21,22,23], synthetic bones/teeth [17, 24], and nanoparticle/nanocomposite [25,26,27,28]. The synthesis of PPVA-ALPO4 composite films is described and their surface structures are examined. The thermal decomposition behaviour of PPVA-ALPO4 composites films is investigated and compared with the decomposition characteristics of pure PVA
