Abstract The present work detailsabout the low temperature curingbehaviour of bio-benzoxazine (C-ddm) prepared using cardanol and diaminodiphenylmethane (ddm)in the presence of polyaniline (PANI). Interestingly, it was found that the curing temperature (Tp) of the benzoxazine monomer (C-ddm) has significantly reduced to 227 ºC from 271 ºC with the incorporation of 2wt% of PANI. The plausible curing mechanism of benzoxazine ring catalysed by PANI was also discussed. Further, the resulted PANI/poly(C-ddm) matrices possessa marginally improvedvalues of glass transisition temperature and char yield. Further, PANI/poly(C-ddm) coated cotton fabric was studied for its UV shielding and surface properties. Furthermore, the UV shielding and surface behaviours of PANI/poly(C-ddm) coated cotton fabrics were explored. The PANI/poly(C-ddm) coated cotton fabric delivered UPF rating as high as 50 + and water contact angle value of162°. In addition, the PANI/poly(C-ddm) coated cotton fabric wasverified for its oil-water separation behavior. It was observed that the PANI/poly(C-ddm) coated cotton fabric offered97.5 % separation efficiency with enhanced flux value of about 6450 L/m2h flux.Thus, the obtained results suggest that the PANI/poly(C-ddm) can be used some of the industrial and environmental surface protection applications.
