Shape memory response behaviour of Neat SMP and SMP with grafted filler
The in-house developed Bio Year of Development : 2017-2018
compatible shape memory polymer
(SMP) made of tBA – PEGDMA matrix Application

+30 wt% PEGDMA: polyethylene
glycol dimethacrylate) with addition devices, orthopedic slab, artificial

when compared to acrylate based ble to skin and bone, Tg = 35°
neat SMP and SMP composites. to 55°C
The addition of grafted HAp filler
has increased the tensile strength Level/Scale of Development :
by 40% and shape recovery rate by TRL-6, Industry standard
185% when compared to the neat
SMP. It also exhibits a higher cell Intellectural Property Rights (IPR) :
viability compared to the neat SMP Indigenously developed in the country
making it better for bio-medical
applications. Major Plant Equipment and
