The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.

An interface structure for detachably interfacing a surgical robot arm to a surgical instrument, the interface structure comprising a main body; and a drive transfer element comprising a first portion and a second portion, the first portion being releasably engageable with a portion of the surgical robot arm and the second portion being releasably engageable with a portion of the surgical instrument; the drive transfer element being movable relative to the main body so as to enable transfer of drive between the surgical robot arm and the surgical instrument.

Surgical drapes reliably maintain sterility in the operating room and enable easy and efficient installation on and removal from a surgical instrument, such as a surgical instrument at the end of a robotic surgical arm. The surgical drape comprises a transitional sheath such that in a deployed configuration a second end of the sheath is spaced relatively away from a first end of the sheath, and in an un-deployed configuration the second end of the sheath is spaced relatively close to the first end of the sheath. The sheath may further include a stiffening member secured to the second end, a pull member coupled to the stiffening member, and at least one access port formed in the first end of the sheath, such that each access port is adapted for the passage of surgical instruments therethrough.
