ABSTRACT = {Increasing usage of foams in various industry sectors had causing serious
disposal problems once it reaches the end of its life-cycle. Herein, PVA-MFC foam
was prepared by freeze-drying using polyvinyl alcohol (PVA) and microfibrillated
cellulose (MFC) as a reinforced material from sugarcane bagasse (SCB). In this
study, the PVA-MFC foam was chemically silylated with Y-methacryloxypropyltrimethoxysilane (MPS) and tetraethoxysilane (TEOS). The wetting ability and
mechanical strength of the silylated <sub>2,20</sub>PVA-MFC foam was greatly enhanced compared with unmodified <sub>2,20</sub>PVA-MFC foam. The silane chemicals (MPS and TEOS)
had been confirmed grafted on <sub>2,20</sub>PVA-MFC foam due to the presence of Si-C and
Si-O-C stretching vibration as showed in Fourier Transform Infrared (FTIR) spectra
and cloud-like coating of porous pore was observed in scanning electron microscopy (SEM) images. The silylated <sub>2,20</sub>PVA-MFC foam (MPS and TEOS) exhibited
a series of desirable properties such as lower swelling ratio and high absorption
capacity of solvents and oils but had low thermal stability in thermogravimetric
(TGA) analysis. The characterization of <sub>2,20</sub>PVA-MFC foam using TEOS was
further investigated. A significant difference in morphology was clearly observed
between the unmodified and silylated <sub>2,20</sub>PVA-MFC-TEOS foam through field
emission scanning electron microscopy (FESEM) images. The X-ray photoelectron
(XPS) analysis of silylated <sub>2,20</sub>PVA-MFC-TEOS foam confirmed the presence of C,
O and trace amount of Si elements. These synthesized <sub>2,20</sub>PVA-MFC foam could be
a promising material for broad range of polymer foam applications.},
