This study investigates methods for improving the heat resistance of polyvinyl alcohol/alkali lignin foam material (PLFM). Tetraethoxysilane (TEOS) was used as a precursor to prepare PLCFM by a sol-gel method. The PLCFM, prepared with different levels of TEOS, was characterized by Fourier Transform Infrared spectrometry (FTIR), Differential Scanning Calorimetry (DSC), and Thermogravimetric Anal...

The significant effect of the addition very small proportions nanofibres and nano-particulates on physical mechanical properties solid materials has been long observed described. electrospun fibres liquid not so widely examined. In this paper, polyvinyl alcohol (PVOH), zein nanofibers in sunflower (Helianthus annuus) oil its viscosity was quantified. For a given amount material, trend increasin...

The possibility to arrange and embed magnetic micro- nanoparticles in thin polymer film systems using flat magnetically patterned substrate templates is investigated. In contrast self-organized particle rows forming by applying a homogeneous field, particles adapt the field landscape of substrate's pattern prior crosslinking. Crosslinking then fixes positions polymer. process tested for composi...
