<div> <p>This paper examined the effect of addition of four polyolefins and mica on colorimetry of ethylene propylene diene rubber (EPDM) composites. The results illustrate that the addition of mica can turn EPDM control from lighter, redder, and yellower to darker, greener and bluer, respectively. The total color change (ΔE) of EPDM/mica composites changed with various types of polyolefins. Ethylene alpha olefin (POE) with lowest crystallinity decrease the Δa of EPDM/mica composites to the greatest extent, while EPDM/mica/Polypropylene (PP) composite, with highest crystallinity of PP, has little change of the lightness value.</p> </div>

Triple Shape Memory

The paper discusses the possibility of using in situ generated hybrid polymer-polymer nanocomposites as polymeric materials with triple shape memory, which, unlike conventional polymer blends with triple shape memory, are characterized by fully separated phase transition temperatures and strongest bonding between the polymer blends phase interfaces which are critical to the shape fixing and recovery. This was demonstrated using the three-component system polylactide/polybutylene adipateterephthalate/cellulose nanofibers (PLA/PBAT/CNFs). The role of in situ generated PBAT nanofibers and CNFs in the formation of efficient physical crosslinks at PLA-PBAT, PLA-CNF and PBAT-CNF interfaces and the effect of CNFs on the PBAT fibrillation and crystallization processes were elucidated. The in situ generated composites showed drastically higher values of strain recovery ratios, strain fixity ratios, faster recovery rate and better mechanical properties compared to the blend.
