The Matrix

High-density polyethylene (HDPE) was used as the matrix material for a carbon nanotube (CNT) polymer composites. Multi-wall carbon nanotube composite films were fabricated using the melt processing method. Composite samples with 0%, 1%, 3% and 5% nanotube content by weight were tested. The mechanical properties of the films were measured by the small punch test and wear resistance was measured with a block-on-ring wear tester. Results show increases in the stiffness, peak load, work-to-failure and wear resistance with increasing nanotube content.

And Function

AbstractPolymers derived from lactic and glycolic acid have achieved success in many medical applications and have been investigated as possible materials for degradable scaffolds required in tissue transplantation. Previous investigators have found significant differences in the behavior of cells cultured on chemically similar polyesters of this family but the mechanisms for these differences have remained unclear.In this study, we fabricated polylactic acid, polylactic-co-glycolic acid, and blend films by melt-processing. The bulk and surface properties of these films were characterized by GPC, DSC, WAXS, SEM, and contact angle. All films were smooth and amorphous and differed only in chemical composition. The films were assessed for their ability to sustain or promote hepatocyte attachment, growth, and function. Cells adhered to and exhibited similar morphology on all substrates. Cells decreased in number to 50–60% of the initial cell number but exhibited high retention of differentiated function on all of the polymer substrates over five days. Cell response was not statistically different on the different substrates indicating that chemical composition, in our range of polymer formulations, does not affect cell behavior.

A series of polypropylene/ethylene-propylene-diene monomer / calcium silicate (PP/EPDM/CaS) composites with different contents was prepared by melt processing using a twin-screw extruder. The composites were characterized. The results showed the particle shape of calcium silicate is honeycomb structure . The heat deflection temperature of PP/EPDM/CaS composite increased with increasing CaS content. The composites had highest tensile strength and the lowest when CaS content was 9.5 phr and 35 phr respectively.
