Properties Of Composites

Shape memory composites of trans-1,4-polyisoprene (TPI) and low-density polyethylene (LDPE) with easily achievable transition temperatures were prepared by a simple physical blending method. Carbon black (CB) was introduced to improve the mechanical properties of the TPI/LDPE composites. The mechanical, cure, thermal and shape memory properties of the TPI/LDPE/CB composites were investigated in this study. In these composites, the crosslinked network generated in both the TPI and LDPE portions acted as a fixed domain, while the crystalline regions of the TPI and LDPE portions acted as a reversible domain in shape memory behavior. We found the mechanical properties of composites were promoted significantly with an increase of CB content, accompanied with the deterioration of shape memory properties of composites. When CB dosage was 5 parts per hundred of rubber composites (phr), best shape memory property of composites was obtained with a shape fixity ratio of 95.1% and a shape recovery ratio of 95.0%.

The aim of this research was to probe the potential application of nano-titanium dioxide (TiO2)/basic magnesium hypochlorite (BMH)-containing linear low-density polyethylene (LLDPE) composite film in grape fresh-keeping. Mechanical properties, transparency, barrier performance and antibacterial activity of the nano-composite membrane were measured, and results showed that the antibacterial zone diameter of TiO2/BMH on pathogen-Aspergillus niger was 31.4 mm, with mixing ratio of BMH/TiO2 to 2:1. It was clearly shown that the synthesized nano-composite films decreased mechanical properties and transparency of the membrane, and also had a significant impact on sensory score, mass loss rate, decay rate, ascorbic acid (Vc) content and titratable acid content compared with LLDPE films. Moreover, the results revealed that the LLDPE antibacterial film can be effectively used for storing grapes, preserving the flavor of grapes and had an obviously effect in prolonging grapes’ shelf life.
