“…In general, the surface treatment of filler particles is beneficial to improve the uniformity of the inclusions in the matrix; in this case, the crystallization property of the matrix resin could be improved owing to the effect of heterogeneous nucleation of the inorganic particles in the matrix. More recently, the authors studied the crystallization properties and thermal stability of polypropylene composites filled with wollastonite, and found that the degree of crystallinity of composite system S3 increased with increasing the CaSiO 3 weight fraction, especially in the case of higher filler concentration. Consequently, the stiffness and strength of the composites could also be enhanced (see Fig.…”

The effects of filler surface treatment and content on the impact fracture toughness and flexural properties of polypropylene (PP) composites filled with wollastonite (CaSiO 3 ) were investigated. The results showed that the introduction of the filler could toughen and reinforce the PP; the influences of the filler surface treatment on the toughness and strength were significant; the values of the Izod V-notched impact strength and the Charpy V-notched impact strength of the composites increased with increasing the filler weight fractions; the values of flexural modulus increased with increasing the filler weight fractions; the flexural strength increased when the filler weight fraction was lower than 10% and then varied slightly. This toughening effect should be attributed to the stress concentration because of strip shape of the filler and to block the development of the notched cracks in the matrix, improving the notched sensitivity to the impact fracture of the PP composites. This study should be helpful to understand the mechanisms of CaSiO 3 reinforcing and toughening PP resin. POLYM. COMPOS., 00:000-000, 2016.

“…DSC is usually used to obtain thermal behavior information, such as the crystallization temperature ( T c ) and melting temperature ( T m ), and to some extent, changes that can be used to indirectly show interactions between the components in polymer blends . In this study, T c and T m were obtained to evaluate the thermal properties of the lignin on PCL in the blend.…”

Maleated lignosulfonate (MLS) produced by esterification with maleic anhydride and unmodified lignosulfonate [in the form of lignosulfonic acid (LS)] were incorporated into poly(e-caprolactone) (PCL) via melt-blending. The obtained MLS/PCL composites and LS/PCL composites were characterized by Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), thermogravimetric (TG) analysis, and electronic universal testing. The FTIR and DSC results show that the interactions between MLS and PCL were stronger than those between LS and PCL, whereas the TG analysis indicated that the LS/PCL composite was more thermally stable than the MLS/PCL composite. The tensile strength of the MLS/PCL blends remained at about 18 MPa when the MLS content reached 50 wt %; this was about 1.7 times larger than that of the LS/PCL blend. The Young's modulus was also enhanced; this indicated an improvement in the mechanical properties. The results show that the maleation of lignosulfonate was beneficial for enhancing the mechanical properties of these blends.

“…Their particle shapes were appreciably different as well. SiO2, which possesses porous particles of a large, specific surface area, exerts a greater effect on the surface of the polymeric coatings; moreover, a layer of PANI is deposited in a stronger and more porous layer owing to the suitable properties of the pigment [28,29]. The film surface produced could also be rougher and more complex.…”

Functionality of polymeric coating, especially in terms of anti-corrosive properties and stability, can be negatively influenced by formation of either bacterial and/or fungal biofilm on its surface. Inhibition of biofilm formation together with improved anti-corrosive properties can be achieved by modification of pigments. Herein, the commercial epoxy-ester resin based polymeric coating was filled with various pigments (natural silicon dioxide diatomite, natural wollastonite, tungstate and molybdate). Pigments was modified by conducting polymers (polyaniline phosphate, polypyrrole phosphate, poly(pphenylenediamine) phosphate and ZnFe2O4). Impact of modified pigments on the surface energy and formation of bacterial and fungal biofilm were tested. The use of various biofilm forming species of both the bacteria and fungi leads to the filling of knowledge gap about their behavior on polymeric coatings.
