“…The decrease in the film transparency as a consequence of the addition of inorganic filler has also been reported with other base polymers. Such an effect of an inorganic filler on the optical properties was explained as being not only due to the types of polymer matrix but also to the compatibility between the polymer matrix and the filler . Hong and Rhim reported that a polyethylene film without clay filler was more transparent than those with clay filler .…”

Poly(L-lactic acid) (PLA) is now a very attractive polymer for food packaging applications. In this study, PLA/poly(trimethylene carbonate) (PTMC)/talc composite films were prepared by solvent casting. The influence of the talc loading (0, 1, 2, and 3 wt %) on the phase morphology of the PLA/PTMC/talc composites and the improvement in the resulting properties are reported in this article. The scanning electron microscopy images of the composite films demonstrated good compatibility between the PLA and PTMC, whereas talc was not thoroughly distributed in the PLA matrix at talc contents exceeding 3 wt %. The tensile strength and elongation at break of the composite films significantly improved (p < 0.05). On the contrary, the water vapor permeability and oxygen properties of the composite films decreased by 24.7 and 39.2%, respectively, at the 2 wt % talc loading. Differential scanning calorimetry showed that the crystallinity of the PLA phase increased with the presence of talc filler in the PLA/PTMC/talc composites. V C 2013 Wiley Periodicals, Inc. J. Appl.

“…The use of natural talc is well known in literature. This filler has been used in the production of composites with different polymeric matrix, such as poly(vinyl alcohol), LLDPE/MWCNT, thermoplastic polyurethane, thermoplastic polyurethane/polypropylene blends, poly(L‐Lactide), polypropylene, poly(lactic acid), among others. Yousfi et al described the use of new synthetic talc as nanofillers reinforcement for polypropylene and polyamide 6 systems and polypropylene/polyamide 6 blends …”

New synthetic Ni-talc was used as filler in the synthesis of polyurethane (PU) nanocomposites by in situ polymerization and to emphasize the contribution of the new material compared with natural talc. Good dispersion of Ni-talc was supported by homogeneous green coloration observed in the polymer matrix. X-ray diffraction (XRD) analyses indicate the intercalation of polymeric matrix into the filler layers by the increase in d 001 -spacing value of the Ni-talc for the nanocomposites when compared to the pristine filler. The nanocomposites obtained with synthetic talc showed an improvement in the crystallization temperature and in thermal stability when compared to pure PU and the composite obtained with natural talc. The young modulus of PU/talc materials containing both Ni-talc and natural talc were slight higher than pure PU. As shown by scanning electron microscope (SEM), Ni-talc fillers were well dispersed into the polymeric matrix probably due to the good compatibility of both phases filler/polymer mainly achieved by the filler OH interaction with the urethane group of the polymeric chain.

“…A large number of researches have been carried out for talc particles pretreatment by using surface active agents such as silane coupling agents, stearate, isocyanate, and so on , which can be chemically grafted onto the talc surface. Nevertheless, the in situ grafting modification during the blending process is a facile and efficient method.…”

Effect of in situ reaction on thermal and mechanical properties of polylactide/talc composites

The biodegradable composites with low cost and excellent mechanical property, namely PLA/talc blends, have been successfully prepared by using epoxidized soybean oil (ESO) as a reactive compatibilizer with the presence of peroxides to accelerate the in situ grafting between talc and other components. The surface treatment of talc powder was performed through the in situ reactions of its rich hydroxyl groups with the epoxide ring of ESO and scission radical of PLA during the blending process. Both FTIR and the extracting experiment results verified that surface modification mechanisms. Such a facile and efficient one‐step process can bring a dramatic improvement on both miscibility and mechanical properties of the PLA/talc composites. POLYM.
