First report on preparation of poly (nitro-carbonate) thermoset polymers for nuclear track detection

Poly(triallyl phosphate) and its copolymers with allyl diglycol carbonate as solid state nuclear track detectors.

“…Preliminary testing of the same was carried out for track detection studies. Initially, time required for development of alpha and fission fragments' tracks in the prepared polymeric films was determined and alpha sensitivity [16] of the films was calculated and is given in Table 2.…”

“…[13][14][15][16][17][18] Interestingly, no polymeric nuclear track detectors containing phosphate functionality are reported so far. We, now report for the first time such phosphate and phosphate-carbonate containing polymeric detectors for nuclear track detection.…”

“…We, now report for the first time such phosphate and phosphate-carbonate containing polymeric detectors for nuclear track detection. We have earlier studied the use of branched monomers like Poly-[N-allyloxycarbonyl diethanolamine-bis(allylcarbonate)] (NADAC), [13] Tris-(2,4-dioxa-3-oxohept-6-en-1-yl)nitromethane, (TDONM), [16] pentaerythritol tetrakis(allyl carbonate) (PETAC) [17] and observed that the polymers derived from them tend to show better radiation sensitivity mainly owing to formation of a denser cross-linked network. We, therefore, decided to use a hexafunctional branched monomer like triallyl phosphate in our present study.…”

In vitro biocompatiblity of modified polycarbonate as a biomaterial

“…Figure S2(B) shows the 1 H-NMR spectrum of the NO 2 -PC. Presence of the nitro group results in a distinct and significant shift of the hydrogen signals of polycarbonate at 7.0, 7.5, and 8.0 ppm [22]. After the nitration process, the proton signal appears downfield, due to the electron withdrawing effect of the nitro group.…”

“…Though there are some reports available on nitration and amination, none of them investigated the anti adhesive characteristic of nitrated and aminated polycarbonate [10]. Hydrophilic materials in addition to their lubricity and biocompatibility, resists microbial adherence thereby preventing the initial stages in the formation of biofilm [11,12].…”
