Styrene-acrylonitrile (SAN) layered silicate nanocomposites prepared by melt compounding

Fire and Gas Barrier Properties of Poly(styrene-co-acrylonitrile) Nanocomposites Using Polycaprolactone/Clay Nanohybrid Based-Masterbatch

“…A number of studies on nanocomposites based on an SAN matrix have been published. These studies have been mainly focused on the organomodified clay effect [8,10,18,19], acrylonitrile (AN) content effect [19][20][21], or the use of compatibilizing agent like PCL [22,23] introduced by melt blending. Whatever the techniques used in these different works, only intercalated structures were evidenced by both WAXD and TEM analysis and thermal and flame retardancy properties have more or less been improved as a function of parameters studied.…”

Synthetic, layered nanoparticles for polymeric nanocomposites (PNCs)

“…Comparative work was carried out by Chu et al 129 The authors prepared PNC based on SAN with MMT or FM pre-intercalated with either 2M2HTA, methyl tallow di-hydroxy ethyl ammonium chloride (MT2EtOHA), tri- phenyl n-hexadecyl phosphonium (3PHDP), or 2MHDI. PNCs were prepared by melt compounding SAN with ca.5 wt% organoclay at 210 o C. All compositions were intercalated with d 001 ranging from 2.85 to 3.51 nm.…”

Negative values of the slope, n ¼ @ ln h à =@ ln v, for four PS-based PNC containing 1 or 2.5 wt% of mineral clay of the MMT or FM type.…”

“…Judging by the values of n, there is no serious difference in behavior for PNC with MMT or FM, although the former clay showed higher yield stress than the latter. Since the original aspect ratio of FM is higher than that of MMT, the information may suggest that FM is more fragile that MMT, and easier breaks down during sonication.Comparative work was carried out by Chu et al 129 The authors prepared PNC based on SAN with MMT or FM pre-intercalated with either 2M2HTA, methyl tallow di-hydroxy ethyl ammonium chloride (MT2EtOHA), tri- phenyl n-hexadecyl phosphonium (3PHDP), or 2MHDI.

Effect of synthetic mica on the thermal properties of poly(lactic acid)

“…However, little attention has been given to the use of synthetic mica/fluoromica, which is characterized by its high ion exchange capacity and high aspect ratio [6] . In the literature, we have found few studies using synthetic mica nanocomposites [7][8][9] . We have investigated the preparation of PLA/synthetic micas nanocomposites by melt blending [10][11][12][13][14] .…”
