Enhancing the material performance of chloroprene rubber (CR) by strategic incorporation of zirconia

Abstract

Chloroprene rubber (CR) composites, embedded with a well dispersed zirconia, within it’s matrix are produced that combine superior reinforcement of zirconia with the other useful composite properties. The in-situ incorporated...

Surface modification of zirconia by various modifiers to investigate its reinforcing efficiency toward nitrile rubber

“…The well-dispersed zirconia particles in the NBR matrix (presented in the later section) are believed to act as an efficient heat absorber and impose a barrier against the degradation of the polymer chains, delaying the degradation of the NBR matrix.

“…[18][19][20] A plenty of reports are available on surface modification of zirconia that has been studied from different viewpoints. This includes a variety of surface modifier, namely, Organosilane: bis(triethoxysilylpropyl) tetrasulfide (TESPT), [19] methacryloxypropyltrimethoxysilane (MPS), [21,22] 3-(amino propyl) trimethoxysilane (APTES) [23,24] ; Surfactants: sodium dodecyl sulphate (SDS), [25,26] cetyltrimethyl ammonium bromide (CTAB), [27,28] lauryl amine hydrochloride [29] ; organic additives: 2-hydroxyethyl methacrylate (HEMA), [30] ethyl 3,4-dihydroxy cinnamate (EDHC), allylmalonic acid (AMA), trimethylolpropane trimethacrylate (TMPMA), [31] carboxylic acid, [32] bis-phosphonic acid, [33] glucose and fructose. [34,35] However, high cost, processing complexity and elevated processing temperature, needed for efficient surface modification, are some major drawbacks to limit their practical applicability in large scale.…”

“…Very recently, we reported efficacy of TESPT and APTES silanes to improve rubber-filler (zirconia) interaction and improved material properties for nitrile rubber (NBR) and chloroprene rubber (CR), respectively. [19,23] To have a deep insight on this issue, the present study has been extended to chemically modify the zirconia surface by three different kinds of chosen modifiers that have never been attempted for the reinforcement of elastomeric composites so far. One is sodium dodecyl sulfate (SDS), a surfactant that has been well used for surface modification of metal oxide particles.…”

“…Such approach has been found to be very efficient and fruitful in the earlier studies. [19,23] This is followed by an in-depth property evaluation of the composites that includes mechanical, thermal, swelling, morphological, dielectric, and rheological studies. The data are analyzed meticulously and interpreted in a comparative manner to assess the effect of three different types of surface modifiers on the surface property of in-situ zirconia in enhancing the material performance of NBR composites.…”
